Ryanair has been hit by the sudden removal of flights from online booking websites, as the low-cost carrier warned of the impact on passenger numbers.
It marks an escalation in the row between Ryanair and online travel agents, as the airline said platforms such as Booking.com, Kiwi and Kayak pulled its flights without warning.
In an update to investors on Wednesday, the Irish carrier said the move would reduce short-term passenger numbers by up to 2pc in January.
Ticket revenues may also be affected as Ryanair said it would respond by lowering fares for passengers booking directly through its own website.
Shares in the company fell 2.6pc in early trading on Wednesday, despite bosses insisting the change would not “materially affect” its full-year traffic or profit guidance.
Ryanair has been in a long-running battle with what it calls “pirate” travel agency websites, as it has accused platforms of overcharging and providing fake contact information.
The airline launched legal action in the US against Booking.com owner Booking Holdings and its subsidiaries including Kayak, Agoda and Priceline.
Booking.com has rejected Ryanair’s claims and has previously accused boss Michael O’Leary of making “false and misleading” statements about its business.
Ryanair said it was not clear what the reason was behind its removal from the sites, but said it could be down to a recent Irish High Court that ruled screen scraper Flightbox could not “unlawfully” scrape Ryanair’s online content for bookings sites.
