What is the best window for booking flights?

The best time to book a flight is one to three months before your departure for domestic airline tickets and two to eight months prior for international flights. ?We call these the 'Goldilocks windows,'? Scott Keyes, founder of Going.com, tells AFAR. ?Not too early, not too late?just right in the middle.?



For 2026 travel, the "sweet spot" for booking domestic flights in the U.S. is generally one to two months (28 to 60 days) before departure. For international trips, the window is much earlier, typically three to five months in advance. Data from early 2026 suggests that 43 days before departure is the statistically cheapest day to book a domestic flight on average. However, if you are traveling during "peak" periods like Spring Break or major holidays like Thanksgiving and Christmas, you should aim to book as early as possible—ideally by mid-October for the winter holidays. While the old myth that "booking on a Tuesday" saves money has been largely debunked by dynamic AI pricing, flying midweek (especially on Wednesdays) remains the most reliable way to save approximately 13% compared to weekend travel. Using tools like Google Flights to set price alerts is highly recommended, as it allows you to catch "flash sales" and temporary price drops that occur outside the standard booking windows.
