When is the best time to book my flight?

When is the best time to book my flight? Prices on last minute airfare can be highly volatile so try to book in advance. At the last minute, airlines know you?re desperate and are willing to pay more. However, occasionally the airlines are desperate to fill seats, so prices might decrease. For travel during popular holidays (i.e. Christmas, New Years, Thanksgiving) and internationally try book at least three months in advance. Most travel sites recommend booking 7, 14 or 21 days in advance, but in my experience the cheapest tickets usually get bought up long before then. So, even for domestic flights I start looking several months in advance.
