Being the spontaneous type is a fabulous way to travel the globe, but it isn't necessarily the cleverest way to land a cheap fare. It's better to book your Washington Dulles Intl.

Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance.
