Over at BootsnAll, Roger Wade asks a question of great interest to travelers: “Which airfare site is the cheapest?” Comparing five traditional airfare sites along with two aggregators– Kayak and Sidestep— Wade comes up with six different “test itineraries” and makes some rather surprising findings.
For the most part, the sites’ prices were pretty close together, but Priceline tied for the cheapest fare four of the six times and found the cheapest fare outright the other two. It was followed closely behind by the aggregators, Sidestep and Kayak.
I’ve always trusted Kayak in the past for finding the cheapest fares, and I especially like to play with the site’s “Buzz” feature, which allows you to look at other users’ searches and see the best fares they’ve discovered. Kayak’s straightforward design and functionality ensure that I’ll still rely on it for finding fares, but in the future, I’m not going to book a flight without first looking at Priceline too.
