Unfortunately, there isnt any silver bullet, best-time-to-buy, that you can mark in your calendar and not have to worry about. We constantly tell would-be flyers to search for flights early and often. As soon as you know you might be taking a trip, start checking fares. This doesnt necessarily mean to buy early in fact, most of the time we suggest waiting. But you want to become familiar with the market on your exact travel dates so you know whats a good fare, whats not, and whats realistic. If you check back frequently, you will likely catch fares that are both on the high side and the low side, and youll have the right perspective to know which is which. Be ready, though. When you do see a good deal, youll want to grab it, as great fares dont typically last for very long.
