Use Airline Consolidators:
You can save hundreds using airline ticket resellers who work with major travel companies to sell tickets at reduced prices.
Here are a few:
Book in Advance:
The more seats there are, the cheaper they will be. Think 21 weeks before your departure date. That means you should be booking those summer vacations right about now.
Fly By The Seat of Your Pants:
Some airlines do offer discounts at 14 days, 7 days, and even three days before a departure date. So, if you are super last minute go ahead and fly by the seat of your bargain pants!
You can save hundreds of dollars if your travel dates are loose. Hotwire, Orbitz and Travelocity are all offering a new flexible date search. The cheapest days to fly are generally Tuesday, Wednesday and Saturday.
Book on the Right Day:
A study by FareCompare.com claims you can get the best deals early in the week-specifically Monday, Tuesday and Wednesday, when airlines post discount prices.
