Fly during the off-peak season

Certain travel destinations have especially high volume during particular seasons. For example, Europe, Hawaii and Alaska are big hits in the summer. Florida, New Orleans and Southern California are the most popular in springtime. Winter is prime for Mexico and the Caribbean, as well as ski and snowboard destinations like the Colorado Rockies. In the autumn, Northern California, the Pacific Northwest and New England draw visitors. Flying during less popular periods can mean extra money in your wallet – yes, please!
