A full guide to developing travel booking engines

Online booking takes up approximately 70% of the $640 billion global travel market, according to Statista. Such a prevalence is massively impacted by the rapid development and expansion of online travel booking engines. No wonder: they offer the convenience and direct engagement that 68% of tourists expect from the booking processes. And in the travel industry, it’s always a choice: be flexible to your clients’ needs — or stay behind.

In this article, we will grasp the components and workflows of booking engines, find their most critical features, and make a choice between a tailored and a ready-made one once and for all.

‍

What is a booking engine?

Let’s start with the booking engine definition. A booking engine functions as an interface and middleman for travelers and suppliers. It processes requests from customers through a user interface and then connects the traveler's request to travel suppliers (hotel, airline, car rental, etc.) and also connects them to their provider's inventory. A booking engine allows suppliers to present their offerings, and travelers to view real-time inventory and book their trips. 

Cantoni's research states that booking engines signify possibilities for conversion without intermediation fees for hoteliers, which makes booking engines a crucial system for the hospitality industry’s main representatives. This study also explains that more hotel website visitors are associated with an increase in bookings through B2B booking engines, which demonstrates the función of booking engines as conversion tools.

Key components of booking engines

When describing the inner workings of travel booking engines, we will focus on the most demanded type. As online travel agencies take up 63.17% of the leisure travel booking market and are absolute leaders in online trip reservations, we will demonstrate what an OTA booking engine consists of. 

Content delivery network (CDN) and load balancer

CDNs leverage a distributed network of replica servers placed in strategic geographic locations to optimize performance and availability. For better content placement, updating, and routing, CDNs use specialized mechanisms. As part of the CDN architecture, when a user requests content, replica selection mechanisms work with cooperative access routers to find the closest and most accessible replica server. Active measurement mechanisms also monitor real-time traffic in the network so that routing is faster.

CDNs host different types of content — static web content, dynamic applications, and streaming media — through distinct processing approaches at the network edge. Load balancers further distribute incoming requests to servers within the CDN to ensure that no single server is overwhelmed, and if a server experiences issues, failovers occur automatically.

Content management system (CMS)

According to Wilson, a content management system is a software application offering users the chance to create, edit, and store digital content with minimal technical expertise. Often, travel companies underestimate how many content updates can be required for a hotel booking process through the engine, or simply assume their developers will occasionally make changes for text, images, and promos. However, when it comes to taking full advantage of marketing campaigns and time-sensitive updates, you may find yourself stuck if there’s a necessity for a last-minute change or your dev team is unavailable.

Specifically, a headless CMS is a type of content management system that allows management from the backend only (through APIs). This facilitates design through a frontend (or multiple if your environment supports it) while allowing any tweaks to the content without altering the core of the booking engine. It's a very flexible tool with lots of options to integrate.

Firewall

A firewall can be a hardware device, software system, or a mix that allows or denies the transmission of network traffic based on defined security policies. It consists of two network interfaces, where an external IP address can be denied access to internal resources. 

Firewalls that control traffic at the networking layer use the packet filtering methodology, where they inspect key information of the packet (source/destination IP address, the type of protocol, TCP or UDP port, and TCP flags) to approve/disallow the response. 

There are also modern systems implementing stateful packet filtering. Stateful packet filtering uses the app connection state information and has dynamic filtering capabilities, where it pings back the source IP to confirm data integrity. Overall, traffic should only enter the internal network of the booking engine system through the firewall's main ingress point.

Relational database and Redis Cache

Relational databases provide a means to store structured data across multiple relational tables. This brings efficiency in search, retrieval, and updating, as well as managing the interrelated data (user profile with booking history, individual inventory, and payment records).

Redis Cache functions as an in-memory data store that retains the frequently accessed data in RAM, resulting in low-latency lookups. Redis employs key-value storage with a unique identifier for each item, allowing for extremely quick access to data. Because Redis provides so many additional features, such as automatic expiration of data, a publish/subscribe mechanism for cache invalidations, and extraordinary throughput, it greatly improves the scalability and the overall experience for users of the internet booking engine.

ECS Fargate by AWS

ECS Fargate works as a serverless compute engine that cuts the need for the manual processes of server provisioning, lifecycle management, scaling, patching, and network configuration. The service automatically handles the management infrastructure to allocate resources and make scaling decisions. Additionally, many services can run in the same Fargate cluster at once — in the booking engine examples, these can be customer applications, APIs, content management systems, authentication services, messaging brokers, and supplier adapters with one containerized environment.

Because of the awsvpc network mode, which links tasks to elastic network interfaces, the platform requires IP target types rather than instance types and integrates with Elastic Load Balancing services that support Application Load Balancers for HTTP/HTTPS traffic and Network Load Balancers for TCP/UDP traffic.

Now that we understand what the key components of a travel booking engine software are, let’s move on to understanding why they are so important. 

Why travel businesses need booking engines

The travel industry isn’t a homogeneous sector. There are many different types of businesses operating within it, and for each, a booking engine system brings unique benefits. Let’s go through the main players and how they enhance their business with this technology.

• Booking engines are great for hotels to receive direct, commission-free reservations, which boosts revenue by cutting third-party platform fees. Another great pro they get is offering guests instant confirmation and round-the-clock booking capabilities, ultimately avoiding overbookings. Also, by decreasing manual data entry and minimizing errors, booking engines for hotels optimize operations. Finally, hotels can make strategic decisions by using advanced analytics from booking data.
• OTA booking engines’ importance can’t be overstated — they help agencies remain efficient and give clients one-click access to a wide range of travel options at competitive prices. Agents can process more bookings thanks to the system's price searches and calculations across multiple suppliers, which drives loyalty and higher revenues. Besides, real-time availability is ensured by integration with supplier inventory systems, which lowers the risk of cancellation expenses that can harm customer relations. Fraud risks are also reduced by the engine's automated payment processing.
• Cruise lines and passenger transport companies require booking engines to make complex inventory management decisions involving cabins, routes, departure times, and ancillary services over several vessels or vehicles. Such engines greatly reduce human involvement, lowering operational costs and making processes faster and cleaner. With an inventory management system that is constantly updated and revenue management capabilities, you can see alternative deals and upsell options for passengers. Lastly, the data collected from the engine allows you to personalize offers and drive loyalty.
• Car rental companies require booking engines to manage dynamic inventory that changes based on availability of vehicles, maintenance schedules, and locations, as there could be tens of thousands of vehicles available in hundreds of locations. A B2B travel booking engine also links to an inventory database for live availability, pricing, type, and details, processing reservations and payment automatically. Advanced distribution options can automatically reassign vehicles when breakdowns occur, while still monitoring the fleet work to avoid over-committed resources at peak times.

As you see, with the needs being very diverse across these types of businesses, many different travel companies take great advantage of getting a booking engine on board. But to get one on your board, too, you should first figure out how this new crewman works.

‍

How hotel booking engines work

To understand how travel booking engines operate, we need to review several interconnected processes that form the basis of their workflows. Let’s start with the nuances of data flow.

Data flow

A booking engine's data flow starts when a guest initiates a room (or tour, transportation) search. This connects to APIs to retrieve real-time pricing, availability, and rules. After the guest selects options and fills out payment details, the system generates a confirmation and creates a booking, and then syncs the booking details to the hotel.

Yuan et al. analyzed the flow of data as it is organized within the Booking.com booking engine. Let’s review the hotel booking best practices for data flows, and how it works in this major OTA.

• Search. Users enter dates, destination, and preferences to start searching for available rooms or other travel services. In terms of Booking.com, it then collects user data (user IP address, browser type, and trends in behavior) through data collection tools.
• API queries. The booking engine connects through travel-related APIs to gain real-time pricing and availability info from hotel systems and reservation networks. Booking.com accesses real-time information from many suppliers, partners, and subsidiaries. The in-use data is assigned across the many channels by the booking channel manager, like Siteminder or Bokun.
• Showing what’s available. The booking engine displays search results in the form of available rooms, accompanying packages, and deals with pricing and amenities. For this function, Booking.com leverages direct search data with the data-driven customer profile developed with business partners to make recommendations about matching content or targeted offers.
• Checkout process. Guests select available rooms, then fill in personal information, payment information via secure forms, and complete the booking transaction. Interestingly, Booking.com obtains explicit data, such as name and payment information, while also collecting data through tracking technologies and device sensors.
• Confirmation and integration. The system sends instant confirmations and automatically imports available data into the hotel PMS and associated systems. For instance, Booking.com  shares reservation data with trip providers (flights, corporate events, car rentals, etc.), payment systems, and technology companies to use the reservation systems for operational and pricing purposes.
• Analytics and follow-up. After guests have booked their lodging or package, the data flows into the analytics systems so that hotels can better understand booking patterns related to guest behavior. For example, Booking.com uses the information to decide market research activities and personalized marketing while adhering to the legal aspects of data collection. 

As you see, the collection and usage of data is one of the most obvious advantages of an online hotel booking system. But to use this advantage, you also need to grasp how this plays out with the way the user journeys are organized within such solutions.

User journey

For an internet booking engine for hotels, the successful completion of the user journey at every stage requires interfaces that are easy to use, intuitive to navigate, displaying real-time information, the ability to pay seamlessly using diverse payment methods, and a strong brand identity differentiating you from your competitors.

Since we already used Booking.com as an example of how it’s generally done, let’s refer to it again. Yunxuangu’s research on Booking.com examined user experiences of journeys shared from college student travelers with this OTA booking engine. Let’s both break down how user journeys are created theoretically, and also throw in the application of this company.

• Users first discover the booking platform through recommendations or search results. Once on the accommodation booking platform, users enter their travel information to begin the accommodation booking search. Booking.com users discover this booking platform through Google search results and referrals. Their site features a straightforward homepage that highlights an accessible search bar.
• Users explore offers for accommodation, comparing costs and features. Then, they sift through the different options using filters. Booking.com, for instance, has improved its filter layout. The initial vertical "Filter by" design was destroying the UX because users were forced to constantly scroll.
• Users use configurable steps to the checkout process, complete with an indicator of checkout progress, filling in personal details, payment info, and then reviewing the selections. Booking.com has a three-step process, with helpful briefs that update users when loading the booking reservation.
• Users receive an immediate booking confirmation via email and the platform, and an electronic summary of the reservation. Obviously, Booking.com also confirms its "Bookings" area that allows users to manage all their reservations in one location.
• After the completion, users can access pre-arrival services provided by the accommodation features, amend bookings, and explore other offerings, like discounted flights, provided by the connection with an airline ticketing system. For example, Booking.com provides trip management tools, with research suggesting that placing reservation options before lengthy property descriptions improves user engagement.

If we dig deeper under the surface of these convenient journeys, there is a complex web of connections between the different moving parts of these solutions.

Interaction between frontend, backend, inventory, and payment systems

Communication from the frontend to the backend of a booking engine system is a complex process. Customer search queries, filters, and booking choices are recorded by the frontend user interface and sent to the backend via secure API calls. In order to retrieve and display real-time information back to the frontend for smooth user interaction, the backend processes these requests, verifies user inputs, and works with multiple systems.

In order for your booking engine to display real-time pricing and availability information, you need it to integrate with an inventory management system. This connection with inventory databases also considers restrictions based on customer search criteria. When reservations are confirmed, this integration instantly updates inventory levels across all distribution channels.

The rate display module, which applies intricate pricing rules like dynamic pricing based on demand, seasonal fluctuations, and supplier changes, receives data from inventory management systems about current availability. Additionally, the system incorporates calculated margins that strike a balance between profitability and competitive pricing.

Finally, since the reservation is the central one of the booking engine features, you need to give your users a secure way to pay for it. Through API connections, the booking process integrates with several payment gateways to manage a variety of payment options and multi-currency transactions for international reservations.  Payment gateways process PCI-compliant, encrypted customer payment data and then send back transaction confirmations.

‍

Must-have features of travel booking engines

Now that we understand the key workflows and integrations, let’s move on to the key functionality of booking engines.

Mobile-responsive design

Today's booking engines must prioritize mobile-friendliness, as travelers increasingly use smartphones and tablets to book their trips. Specifically, as many as 70% of searches for destinations and accommodations are conducted on mobile devices, and 45% proceed to booking in the same manner. 

There are some requirements to make this experience spotless. A responsive design functions the same across any type of device and provides a more natural touch-based experience. Moreover, if your B2B booking engine is connected to corporate travel management apps, mobile responsiveness is essential, as business travelers have a tendency to book travel in between meetings and while in transit.

Multiple payment options

To reach a global audience, multiple payment options are needed. They generally include credit cards, debit cards, digital wallets (like PayPal, Apple Pay, and Google Pay), and payment types that are specific to the region your business operates in. Flight booking engines, specifically for travel agents, can also offer corporate types of payment options such as virtual credit cards and invoice billing.

B2B booking engines can use different payment terms like net-30 billing, while B2C booking engines primarily focus on instant payment processing with buyer protection.

Real-time availability and pricing

Real-time availability and pricing of the offerings in your booking engine rely on dynamic inventory management strategies to ensure that listing the travel inventory is based on live pricing. This helps ensure no offer is overbooked and the accurate pricing is always shown at the right time.

The hospitality and airline industry digitalization has caused connectivity that makes it happen. First, there should be seamless integration through GDS connections, so they can update live flight schedules and fare changes. This is especially important for the booking engine for travel agents — they want to know right away that the travel they booked is confirmed, and what the pricing structure will look like for their customers from a competitive standpoint. 

Advanced search and filtering

There is a grave problem with many of today’s travel booking websites. 25% don't have the on-site search functionality at all, and even if the rest do, 40% don’t offer widespread industry-specific filters. How can a hotel's web booking engine fix it?

Sophisticated search tools with multiple filters (price range, location, rating, amenities) empower travelers to find what they want. For example, a flight booking engine for travel agents needs specialized filters for departure times, airlines, stops, and cabin classes. B2B platforms often have filters to comply with corporate policies, while B2C engines offer simpler visual filters and recommendation algorithms for end users.

Multi-language and multi-currency capabilities

Multiple languages and automatic currency conversions provide global access to the platform without imposing barriers to international travelers. Surely, it gives travelers the ease of mind — reading and filling in details in the native language and not having to check the exchange rate on external sources is a big pro for you to earn a loyal customer base.

Exchange rates should be uploaded automatically, and all content should be localized to create an enhanced user experience. This feature is often more important for B2B flight booking engines that serve on international routes and administer corporate travel programs for companies with global operations.

Integration capabilities

Connecting with PMS and CRM tools helps you connect the booking engine with internal processes for clear accounting and operations. Besides, links to third-party apps fluidly form a complete ecosystem that helps you add any sources that make your offerings robust and attract a wider global audience. 

There is a differentiation in the integrations based on the type of engine we’re talking about. Flight booking engines integrate with the GDS systems, the airlines API’s, and travel management systems. The best booking engine for B2B hospitality should integrate deeper with corporate expense management tools and HR systems (and so on), while B2C platforms will connect to social media and marketing automation tools.

Analytics and reporting dashboard

Data analytics and reporting capabilities provide insight into booking patterns, revenue streams, and customer insights. There are some distinctions between the different types of engine and the KPIs they track.

• For an online booking engine for travel agents, tracking KPIs and sales commissions is key. 
• For airlines, digital solutions provide great reporting on route profitability and load factors. Additionally, B2B booking engines typically have very comprehensive corporate reporting with cost center allocations and policy compliance metrics to track and measure effectiveness. Finally, for B2C platforms, the focus is on conversion optimization analytics and user journey reporting.

With the basics defined, let’s try to build our own comprehensive strategy to build your own booking engine.

Building a custom booking engine 

Based on 15 years of experience in the travel and hospitality industry, COAX has developed a roadmap that helps create robust and efficient solutions for travel booking. Let’s go through this step-by-step guide.

• Perform market research. Thoroughly analyze your competitors to discover market gaps and understand your audience's specific needs and pain points. Conduct a comprehensive hotel booking engine comparison, analyzing their pricing and feedback to assess which solutions are missing from your chosen niche.
• Validate business idea and pick a unique selling proposition. Use frameworks (for instance, Lean Canvas) to validate your ideas by documenting the customer problems, solutions, and unique value propositions. Develop a unique competitive advantage that sets your booking engine apart from other established players in the market.
• Create app personas. Identify and document all types of users who will be using your platform, what their roles and responsibilities are, and what their specific user needs are. Develop character-like personas that will help you focus on user experience design and feature priority during development.
• Select a monetization model. Determine if you want to select between an agency model (commission-based, like Booking.com), a merchant model (bulk purchasing-deciding, like Expedia), or an ad model (ad revenue, like TripAdvisor), or consider that you may want to choose a hybrid combination of these business models to create your own unique position to maximize profitability in the marketplace.
• Select inventory sources. Figure out how you will source your bookable inventory from options such as GDS integration, reselling travel partners, or if you’re developing a multi-vendor marketplace. For flight booking engines, plan to integrate direct connections with airlines and enter into corporate rates so you can generate exclusive inventory and maximize margins for travel agents, and for the booking engine for hotels, consider connecting with the bedbanks and channel managers.
• Startup user experience prototypes. Build wireframes and interactive prototypes to depict journeys and core booking flows before development has started. Be sure to test with prospective users to ensure usability and validate areas for improvement early on.
• Create interface design. Build a full design system that has cohesive visual elements, colors, and component libraries that align with your future brand. The OTA booking engine user interface should have elements aimed at conversion to maximize completed bookings, such as trust signals, social proof, and a quick check-out process.
• Go into development. Develop the front-end user interfaces and back-end architecture, while also implementing core booking functionality, e-commerce checkout using payment gateways, and integrations with inventory sources. Create strong APIs and databases that can manage high traffic and complicated booking scenarios.
• User testing. With users, you will unfailingly want to do a thorough test to find usability issues, as well as determine where the booking flow might cause some confusion, conflicts, or abandonment. You need to look at automated testing tools to cover all the booking scenarios, as well as some manual end-to-end testing on a set of devices.
• Launch your solution. Deploy your booking engine with the appropriate monitoring solutions and be ready to get your feedback for continuous improvement and optimization. Also, expect further maintenance, business requests, feature updates, and further scalability as your user base grows and markets continually change.

Surely, such a complex development as needed for a comprehensive travel booking engine comes with some substantial pricing tag. Let’s break down what it consists of.

Cost

The cost of a booking engine will be based on a series of interconnected factors, which could potentially have a substantial impact on the final investment needed. The main cost drivers for your booking engine system are usually the following:

• Type of features (simple search and booking functionality, versus AI recommendations & dynamic pricing algorithms — in real-time — across a variety of suppliers).
• Platform coverage (web-only solution — guaranteed response times — v.s. fully responsive web, iOS, and Android apps, with admin dashboards and agent portals).
• Team structure (local/hired developers — outsourced offshore developers — or hybrid teams with a variety of experience/skillsets from junior to senior architects).
• Type of integrations (to payment gateway, GDS, channel manager, PMS, CRM, or marketing automation services).
• Design complexity (sticking to template-based UI vs. custom brand design vs. replacing an entire UX/UI with UX design, user research, user scenario, and testing).
• Backend architecture (basic booking system v.s. microservice architecture to support millions of active users, synchronized real-time across agents, providers, suppliers, and coordinated business logic).
• Compliance and security needs (SSL v.s. PCI DSS compliance, GDPR compliance, and fraud detection).

Since there are multiple moving parts to this equation, it’s not easy to precisely predict the cost on the spot. However, you can use the following formula to formulate the baseline investment:

Keep in mind that the development hours are driven by feature area scope times. However, with COAX, you get what you need the most to see the investment clearly: transparency. When we provide travel software development services for businesses, we always start with an accurate definition of the necessary team composition, stack, architecture patterns, and integrations, and break down the hourly cost precisely. 

With us, you are never surprised at the cost of your travel booking engine software development. We lay it all down for you openly, so you know exactly what to expect and can make definite plans to scale as much as your resources allow.

In some situations, the offerings of a ready solution don’t match your needs. For instance, if you own a hotel chain, some of the hotels under your umbrella might be low-cost, and some of the luxury segment, requiring different commission structures. Or, if you own a travel agency, you need other integrations other than the standard GDS and channel manager ones that most of the options offer. Or the user flows don’t match your actual operations — it happens quite often.

In this case, the travel booking engine app development services that COAX offers are a good way to use the proven expertise in travel booking engine software creation. No limitations, negotiating commissions or pricing structures — there are no structures to begin with. You own the solution completely and don’t have to eat up your earnings on endless yearly or monthly renewals. Besides, we can add any features to the solution post-launch, based on the actual user experience, not hunches that this will work after you pay for some fixed plan.

Custom/ready

The choice between ready-made and custom booking engine solutions is an important step in your business development. It’s based on a number of important factors that have the power to make or break the success of your new beginning.

Let’s start with ready-made ones. You can confidently look through our list of hotel booking engines to pick the one that fits most, if your company fits these requirements:

• Your booking process follows standard patterns. Your tourists search, then select the offerings by filtering, book a certain option, and then pay. Nothing extra.
• You want to enter the market right now. Even if there aren't many customization options and the solution appears similar to competitors, you need a working booking engine deployed in two to six weeks and want to start taking direct bookings right away.
• You have financial limitations. The initial investment is modest and will roughly just fit the first monthly fees, and you would rather have predictable recurring expenses than large upfront development costs.
• Your needed integrations are pretty typical. You might need some common PMS systems (for instance, the Opera or RoomMaster one), well-known payment gateways (PayPal, Stripe, for instance), and standard channel managers, which are already supported by the majority of ready-made solutions.
• Your technical resources are close to null. You don't have enough in-house developers or specialized IT personnel to manage custom solutions. If this is the case, off-the-shelf booking engine systems come in handy with pre-built templates, standard payment processing, basic analytics dashboards, mobile responsiveness, SSL certificates, hosting infrastructure, customer support, and vendor-managed software.

If all of these points correspond with your situation, confidently return to our hotel booking engine comparison and choose your tool. However, custom options give you the freedom, ownership, and full flexibility. These will fit your business if these are true for you:

• You offer unconventional booking experiences. Your property provides services that aren’t possible with standard platforms, such as multi-property packages, intricate group reservations, dynamically priced event spaces, or specialized lodgings (glamping, boat rentals, co-working spaces).
• You need advanced integrations. Your business requires smooth communication with third-party APIs, proprietary systems, legacy databases, custom CRM platforms, or specialized payment processors that aren't natively supported by ready-made solutions.
• You truly want to stand out. Personalized recommendation engines, or specialized features like virtual tours, AI-powered conversational booking widgets, or blockchain-based loyalty programs, are the components that will set your brand apart from the competition, and they can only be created customized.
• You need to implement complex business logic. Your pricing includes multi-tiered loyalty programs, corporate contract management, specialized commission structures for various distribution channels, and sophisticated algorithms (dynamic pricing based on weather, events, and competitor rates).
• You want to scale as much as you want. You want to make money from your booking platform by licensing it to other properties, need white-label travel booking engines for franchise partners, process thousands of bookings each month, or need total data ownership.
• Your technical capabilities are solid. You have internal expertise or reliable managed development partners to manage security updates, performance optimization, and feature development, as well as a dedicated development resource and a monthly maintenance budget.

In the end, the decision hinges on achieving a fragile balance between long-term competitive advantage and speed to market. While custom development produces distinctive value propositions that can support premium pricing and foster greater customer loyalty, ready-made solutions are excellent at getting you up and running quickly with proven functionality.

With COAX, it’s easy to adopt a hybrid approach. We can integrate any ready-made hotel booking engine or a solution for OTAs into your existing website. Also, nothing limits us from building additional API integrations from the existing connectors and documentation, to expand the capabilities of the off-the-shelf solution you choose. Custom-developed or ready tool integrated — we are always there for you to help.

FAQ 

What is a hotel engine, and how does it differ from a booking engine for OTAs?

A hotel recommender system, such as the LSTM-HOA model conducted by Garima, extracts preferences from guest booking data, reviews, and ratings. They examine behavior patterns, seasonal trends, and contextual factors, and then offer individualized hotel recommendations based on collaborative filtering and predictive analytics. In contrast, OTA booking engines also concentrate on inventory management and transactions, apart from the data-driven personalization.

What are the uses of AI in hotel booking engines?

AI's intelligent automation and personalization is of great use for hotel reservations:

• Optimizing prices dynamically according to demand trends.
• Customized suggestions utilizing cooperative filtering algorithms.
• Processing natural language for visitor inquiries.
• Inventory management using predictive analytics.
• Automated recommendations for upselling and cross-selling.
• Updates on availability in real time.

As an example, the 24/7 Conversational Booking Engine solution provides instant booking confirmations from an AI-powered chat assistant.

What are the barriers to adopting OTA booking engines?

The main obstacles are: 

• The lack of personalized service recommendations.
• Guests' preference for in-person interactions with travel agents.
• Misgivings about automated systems.  

In order to keep offerings efficient and automated and still drive those personalized guest relationships, consider implementing hybrid models that combine AI efficiency with human touch. These models include training agents to use AI-powered tools for faster service, integrating live chat support within booking engines, and developing conversational AI that can escalate to human agents when necessary.

How does COAX ensure the branded experience of the booking engine?
