KAYAK is owned by Booking Holdings (the United States, NASDAQ: BKNG), which acquired the brand on 21 May 2013.[1][2] KAYAK was founded in 2004 in Stamford, Connecticut and was independent until 2013.
KAYAK searches other travel sites rather than selling tickets itself, and was founded in 2004 by people who had built Expedia, Travelocity and Orbitz. Priceline acquired it in 2013 for about $1.8 billion, so a metasearch tool that ranks agencies is owned by one of them.
Priceline acquired KAYAK for about $1.8 billion. A metasearch site that ranks travel agencies against each other thereby became owned by one of the largest of them, which is the arrangement most of its users would be surprised by.
