All customers booking with Booking Holdings brands, which include Booking.com, KAYAK, Priceline and Agoda, will now have access to Ryanair flights with full price transparency.

Customers who book Ryanair flights through Booking Holdings brands will also automatically have access to their myRyanair account without needing to complete Ryanair’s customer verification process.

Ryanair had previously brought US court proceedings against the online travel agent (OTA), which it accused of unlawfully accessing its website without authorisation in order to offer Ryanair flight tickets to its customers.

Dara Brady, Ryanair’s chief marketing officer, said: “This new partnership with Booking Holdings is welcome news for all customers who book or compare prices through Booking.com, KAYAK, Priceline, and Agoda, where they will be assured of full price transparency and receive all essential travel updates from Ryanair directly to their phone.

“This partnership shows how approved OTAs and Ryanair can work together to protect and benefit consumers, giving them more choice at lower fares.”

Todd Henrich, Booking Holding’s senior vice-president for corporate development, added: “We are pleased to partner with Ryanair to continue giving travellers greater choice and value when booking their journeys across our platforms.

“In bringing together access to Ryanair’s low-fare flights and network of more than 235 destinations with the innovative, intuitive technology, ease and flexibility offered by our brands, this partnership builds on our commitment to provide a trusted, seamless booking experience to customers all over the world.”
