How Transavia turned empty seats into post-booking revenue in just 12 weeks.

Context

Transavia France, Air France-KLM’s low-cost subsidiary, carries 14 million passengers per year across 120+ destinations with a fleet of 75+ aircraft. Their model relies on almost entirely non-refundable tickets — a commercial necessity, but a major structural blind spot: when a passenger can no longer travel, they have no good option. The ticket is lost, the seat flies empty, and the airline misses a revenue opportunity on a flight that could have been optimised. On high-demand flights, every seat represents real margin — and that margin was disappearing with no warning and no solution.

Achievements

Transavia partnered with Fairlyne to deploy SeatResale in just 12 weeks, with no changes to existing RM systems, fare structures or booking flows. The integration was fast, non-invasive, and required minimal lift from Transavia’s teams.

• Fully branded Transavia interface: passengers declare a no-show in just a few clicks, directly within Transavia’s own channels — a simple, transparent experience that turns frustration into loyalty
• Dedicated RM cockpit: Revenue Management teams control their own eligibility rules, recovery thresholds and compensation levels — at flight or network level, with full visibility and zero disruption
• Zero changes to fare structures, booking systems or existing RM logic
• Fairlyne managed the full implementation, from technical integration to RM onboarding, with continuous support after go-live
