The Priceline Group has acquired Momondo Group in a deal worth $550 million.
Momondo is a European travel meta engine that offers flights, hotels and car rentals as well as global flight comparison site Cheapflights.
It will operate under the Priceline Group’s leading travel meta brand, Kayak.
"Metasearch is appealing to consumers and we're keen to expand our global footprint," said Glenn Fogel, CEO of The Priceline Group. "Momondo and Cheapflights will be nice additions to our meta portfolio under KAYAK."
"Momondo and Cheapflights have built great products serving loyal users across Europe," said Steve Hafner, CEO, KAYAK. "We're looking forward to learning from them and sharing best practices as our brands expand globally."
Priceline’s other acquisitions include Booking.com, Rentalcars.com and Opentable.
