In July 2025, Fairlyne, a Paris-based startup, launched a white-label Resale-as-a-Service platform for Transavia France, which is now live across the airline's digital channels. Passengers with a non-refundable fare who can no longer travel can initiate a resale request, with the airline deciding whether and when to recover the seat and compensate the original buyer, typically via voucher or loyalty currency.

This is the sixth edition of T2RL's report on the market shares for airline revenue management (RM) systems. Published in May 2025, it gives an insight into the current challenges and opportunities faced by airlines and vendors within the domain of revenue management and pricing optimisation. Market share information is based on 2024 annual passenger volumes adjusted to include current migrations and implementations as of 31st March 2025.

T2RL measures the market for RM systems on the assumption that the value of that market is proportional to the total number of passengers carried. It was in the region of 4.8 billion passengers in 2024, up from 4.3 billion in 2023 and 3.3 billion in 2022. For the first time annual airline passenger numbers have exceeded those in 2019, before the Covid pandemic.

This 29 page report presents the detail and complexity of the current global situation.

The transformation of airline commercial processes and technologies to an environment based on Orders rather than PNRs and tickets is now under way. Historically many airlines have acquired their central commercial systems from a single provider in the form of a Passenger Services System (PSS). This includes the core functions of inventory, reservations, ticketing and check-in. They may add other systems such as revenue management or internet booking engines which access the database of the PSS and augment its functions.

In the world of Offer Order Settle Deliver, which is also referred to as Modern Airline Retailing, some airlines will continue to buy a comprehensive service from a single vendor. However there is an expectation, not least from the standards-setting body, IATA, that it will be open to airlines to acquire technology in a modular manner and combine components from multiple vendors to create a unique commercial stack.

The purpose of this document is to identify where in the OOSD environment familiar functionality will be located. In many cases there will not be a simple one-to-one correlation between the old and the new.

This report marks the start of T2RL's coverage of the market for revenue management and dynamic pricing of ancillary products. This market is beginning to emerge as more airlines see ancillary revenue increasing in importance. It is now possible to justify the investment required to optimise the revenue derived from non-flight products. Most of the vendors associated with revenue management of flights have launched initiatives to bring ancillary revenue into their scope but it is too soon to draw any conclusions about which of them will be most successful in this new field.
