GDS to NDC migration services
Airlines are shifting from legacy PNRs and fare codes to dynamic offers and custom bundles. The problem is that you’ll have to run both systems side-by-side for years while existing GDS tickets run their course.GDS to NDC migration services at COAX Software help your platform become bilingual. NDC arrives airline by airline, old bookings keep being serviced, and agents and travelers barely notice the change.
Industry leaders we work with

What our GDS to NDC migration services include
Content gap analysis by airline
We compare what each of your key airlines offers through the GDS versus NDC: fares, bundles, extras, and price differences. You see where staying on legacy content is costing you sales or margin.
Shopping across both channels
GDS and NDC results merge into one list, with duplicates removed and fare families lined up. Travelers see the best option without needing to know where it came from.
One booking model for PNRs and orders
Behind the scenes, a single internal model handles both ticketed PNRs and NDC orders. Your back office, reports, and customer accounts work the same way regardless of channel.
Servicing two worlds at once
Changes, refunds, and schedule disruptions follow the right path for each booking type. A ticket issued last year and an order booked today can both be changed from the same screen.
Agent tools for the new world
Agents used to cryptic GDS commands get clear screens for offers, orders, and servicing. Training runs alongside each rollout stage, so the desk keeps moving.
Reporting and accounting adjustments
Commissions, settlement, and revenue reporting change shape with NDC. Mid- and back-office exports are updated so finance keeps getting numbers it can trust.
Airline-by-airline cutover
Carriers move to NDC in planned waves. If an NDC connection misbehaves, traffic can fall back to the GDS path while the issue gets fixed.
Modernizing the old air booking code
Legacy booking modules get wrapped and gradually replaced with cleaner services. Each piece can then be tested, scaled, and changed without touching the rest.

Why air sellers trust COAX Software with GDS to NDC migration services
Used to running two systems at once
We’ve swapped core pieces of live platforms while they kept selling, including Re:Plan’s payment engine, which moved without a single interruption. Parallel running is how we work by default.
Agents trained alongside every stage
Each rollout comes with screens, guides, and short sessions for your desk. Productivity holds steady while habits change.
Every airline gets its own cutover
Carriers move one at a time, with a fallback path ready. One difficult NDC connection never holds the rest of your air business hostage.
Commercial homework done early
NDC access depends on airline, aggregator, or GDS agreements. We map those requirements at the start, so technical work never waits on a contract nobody requested.
FAQ
COAX Software does. For air sellers, that often means GDS to NDC migration services: a shared booking model, dual-channel shopping, airline-by-airline cutover, and modernized booking code underneath. We also modernize booking marketplaces, back offices, and payment systems.
The strongest partners change systems while the business keeps earning, keep old and new data reconciled, and train your people along the way. COAX Software works this way, backed by ISO/IEC 27001 and ISO 9001 certification and a 4.9/5 Clutch rating.
Not overnight. Experienced agents can keep their familiar tools for GDS bookings while new screens handle NDC offers and orders. Over time, most teams shift to the new screens because servicing gets easier there.
COAX Software offers them for agencies, OTAs, operators, and marketplaces. Each project starts by recording how the old system behaves, then replaces it in stages with tests and fallbacks at every step.
COAX specializes in it, with 16 years of engineering and travel as a core industry. Our long-running client partnerships, including more than five years with Re:Plan, show we stay around for the full journey.
Not anytime soon. Most air sellers run both for years, since some fares, airlines, and existing tickets stay in the GDS world. A good migration makes that dual setup comfortable to live with.
Start with carriers that bring the most volume, add the most surcharges on GDS bookings, or offer content you can’t get otherwise. The content gap report ranks your airlines on exactly those factors.
