(Reuters) – Priceline.com, the online travel agency known for its name-your-own-price auctions, posted a higher-than-expected quarterly profit on Thursday, boosting shares in extended trading. Darren Huston, the former chief of Booking.com who became chief executive officer and president of Priceline.com in January, said bookings for hotel stays, airline tickets and rental cars picked up at the end of the quarter for the start of 2014. He said the Priceline brand performed well, aided by airline ticket sales and rental car reservations. Priceline, which owns Kayak.com and Agoda.com, is boosting its presence in fast-growing markets such as Asia.
