Priceline, the world's largest travel booker, brought in $35.22 per share on $4.43 billion in quarterly sales, both which beat the Zacks consensus of $34.31 per share and $4.31 billion, respectively. TripAdvisor beat on the bottom line by 2 cents to 36 cents per share on a big sales miss of $439 million, well beneath the $454.3 million expected.
