That depends on where you live and the airline. Shop around for specials. Use all of the resources you can find. Expedia, travelocity, yahoo.travel, etc.
Change travel days, Tuesday & Wednesdays, are usually the best; change the length of stay to meet some of their requirements. Play with numbers, days, length of stay, etc.
