BOOK ONE-WAY FLIGHTS FOR AS LOW AS $49: The Alaska Airlines three-day winter sale has flights for as low as $49 each way. But you'll want to book quickly, since the sale ends at 11:59 p.m. PT on Feb. 6.

Travel is full of unexpected costs. Suddenly there's a resort fee, a hotel parking fee, and an eye-watering bill for airport food when the plane gets delayed. In order to compensate for those surprise fees, book flights that don't break the bank. Instead of paying full price, check out the winter sale at Alaska Airlines.
