The plane truth.

If you're planning a trip away this summer, this month's Glamour Magazine recommends three travel search engines, sidestep.com, kayak.com and mobissimo.com.

They search over 100 airline websites, bring you the best price and then link you directly to the airline's site to buy your ticket. And you avoid the user fees often levied by the search sites that book the tickets for you.

We gave them a spin, and they're all much of a muchness, with sidestep.com just ahead for speed and search flexibility.
