Accelya Achieves IATA 24.1 ARM Recognition Across End-to-End Airline Retailing

Windsor, UK – May 20, 2026

Recognition across Shop, Order, Pay and Account supports Accelya’s position as a partner for airlines seeking to modernize retailing without being locked into a single system of record or vendor-controlled stack.

Accelya, a global software provider to the airline industry, today announced that its airline retailing capabilities have been recognized under IATA’s Airline Retailing Maturity, or ARM, index for IATA 24.1 capabilities across key areas of the modern retailing journey.

Accelya’s IATA 24.1 ARM recognition spans Shop, Order, Pay and Account, reinforcing the breadth of its capabilities across the commercial, operational and financial workflows that underpin modern airline retailing.

For airlines, this matters because modern retailing cannot stop at offer creation. A richer shopping experience only creates lasting value if the resulting order can be managed, paid for, accounted for, serviced, delivered and settled with confidence. Accelya’s recognized 24.1 capabilities reflect the company’s investment in supporting the full airline retailing lifecycle, not just the digital storefront.

IATA’s ARM index provides the industry with visibility into the journey toward airline retailing maturity. Its Capabilities Verification pillar validates capabilities enabled by IATA airline retailing standards across six streams: Shop, Order, Pay, Account, Settle and Setup. IATA has stated that the ARM index supersedes the former NDC and ONE Order certification registries, creating a more comprehensive industry reference point for modern airline retailing capabilities.

“Modern airline retailing does not stop when an offer is created,” said Tim Reiz, Chief Product Technology Officer at Accelya. “The value comes when airlines can connect offers to orders, payment, servicing, accounting, delivery and settlement. Accelya’s IATA 24.1 ARM recognition reflects the breadth of our platform and our commitment to helping airlines modernize retailing as an end-to-end operating model, not a set of disconnected point solutions.”

Accelya’s FLX ONE platform is designed to help airlines modernize across Offer, Order, Settlement and Delivery through an open, modular architecture. Built for airline scale, FLX ONE supports approximately 50% of global NDC volumes, settles more than $100 billion annually, and processes 8 trillion offers per year.

This latest recognition supports Accelya’s broader strategy to help airlines modernize progressively, without being constrained by monolithic technology stacks. Accelya’s FLX ONE platform is designed around open, modular and standards-aligned capabilities that help airlines connect offer, order, payment, accounting, servicing, delivery and settlement workflows at their own pace.

Accelya continues to invest in the next phase of modern airline retailing, including AI-enabled workflows through FLX AIViator, collaboration with AWS, and engagement with IATA and member airlines on the Modular Exchange Framework. These initiatives reinforce Accelya’s position as a partner for airlines seeking to modernize across the traveler journey while retaining control of their technology strategy.
