Hafner discussed the future for Kayak, which bought rival travel search aggregator SideStep in late December. "Our goal is simple," he said. "We want to be the number-one travel site for consumer information world wide."
In terms of volume, Hafner said that the company would round out the month with about 45 million queries. "That's more than Priceline, but half the size of Orbitz," he said. "We do more searches per day than United Airlines."
He also said that the next big step would be to turn Kayak into a vertical ad network--and unset the competition in terms of eyeballs and ad dollars. "Any place that consumers go to for travel information and that advertisers spend money on is a competitor of ours," Hafner said. "Plain and simple."
