Airline technology retail specialist Accelya was behind over half of all global New Distribution Capability (NDC) transactions in 2024, according to latest data from consultancy T2RL.

NDC is the data scheme introduced by IATA to become the backbone of truly modern digital airline retailing.

According to the latest data from T2RL, Accelya has maintained its global market leadership for a second year, powering the majority of airline NDC sales.

Accelya said with recent research from Atmosphere Research Group showing two thirds (66%) of airlines have implemented NDC, volumes are expected to triple over the next three years from seven to account for 21% of total bookings.

NDC API volume data from T2RL revealed Accelya achieved a 53.3% share of global NDC volumes, well ahead of the next closest third-party IT provider.

Accelya said “this market leadership reflects the trust airlines place in Accelya to deliver the scale, resilience, and commercial agility required to modernise their retailing strategies”.

Sam Gilliland, chief executive of Accelya, said: “There’s a difference between offering NDC and making NDC real for customers.

“For several years, we’ve led the industry in driving real NDC adoption and bookings. With more than half of global volumes continuing to run through our platform, we’re helping airlines go beyond pilots and into scalable, revenue-generating retailing and setting a foundation for Offers & Orders.”

The Accelya cloud-native platform, built on Amazon Web Services, supports the airline industry’s transition to IATA’s vision for an Offer Order Settle Deliver future.

The platform allows carriers to reduce reliance on legacy PSS systems and unify pricing, order management, delivery, and settlement into a single retailing architecture.

Gilliland added: “We’re not just powering NDC, we’re enabling the next generation of airline commerce. From offer creation to fulfilment, our customers are unlocking new retailing models and delivering better experiences across channels.”
