How far out to book flights for lowest price?

Timing plays an important part. Specifically, plane tickets usually don't get cheaper closer to the departure date. Instead, flights tend to be the most inexpensive when you book between four months and three weeks before your departure date.



In 2026, the "sweet spot" for booking the lowest flight prices remains approximately 1 to 3 months in advance for domestic flights and 2 to 8 months for international travel. The old myth of "booking on a Tuesday" is largely obsolete; modern airline algorithms use real-time demand and "dynamic pricing," meaning prices can change every hour. For domestic trips, data suggests that booking roughly 28 to 45 days before departure yields the best results. For major international holidays or peak summer travel, you should look closer to the 6-month mark. A critical strategy in 2026 is using "Price Tracking" tools like Google Flights or Hopper; these allow you to set an alert and wait for a "price drop" rather than guessing. Booking too early (more than 10 months out) can actually be more expensive, as airlines often set high "baseline" prices before they begin adjusting them based on actual sales data.
