Can You Get a Deal on Summer Airfare?

Summer airfare deals can be as elusive as the sun you want shining on your vacation. So what's the secret to getting the best price?

The Associated Press asked Expedia to look at historical travel data and come up with some pointers.

Expedia analyst Daniel Kissin said a lot has to do with timing, whether you should book early or wait.

Based on an analysis of ticket prices over the last four years, Expedia found that the best time to book for the Fourth of July weekend, for instance, was between one and two months in advance.
