How early should you book a flight to get the best price?

How far in advance should you book a flight to get the best deal? 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.



For the best prices in 2026, data suggests a "Goldilocks Window" of 1 to 3 months in advance for domestic flights and 2 to 8 months for international travel. Booking too early (more than 10 months out) can actually be more expensive, as airlines often set high "placeholder" prices before they begin their competitive yield management. Conversely, booking less than three weeks before departure is risky, as prices typically spike when business travelers begin booking last-minute. For peak seasons like summer or Christmas, you should aim for the earlier end of these windows (4–6 months ahead). While the old myth of "Tuesday at midnight" is largely obsolete due to modern AI-driven dynamic pricing, flying midweek (Tuesday or Wednesday) remains statistically cheaper than traveling on Sundays or Fridays. Using fare-tracking tools like Google Flights or Skyscanner to set Price Alerts is the most effective way to snag a deal in 2026, as it allows you to capitalize on "flash sales" or lower-demand periods that the algorithms create in real-time.
