How early should you buy an international flight?

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 international flights is generally 4 to 7 months in advance. According to 2026 airfare data, booking too early (more than 10 months out) often results in paying "base" prices before airlines release competitive sales, while booking too late (less than 6 weeks out) sees prices skyrocket as business travelers fill the remaining seats. For specific regions: book Europe 5 months ahead, Asia 6 months ahead, and South America 3–4 months ahead. If you are traveling during "Peak Season" (July/August or late December), you should extend that window to 8 to 10 months to ensure seat availability. In 2026, using price-tracking tools like Google Flights or Skyscanner is essential, as airlines now use AI-driven dynamic pricing that can cause fares to fluctuate daily. A pro tip for 2026 is to book on a Sunday and aim for a Tuesday or Wednesday departure, which can save you an average of 15% compared to weekend flights, regardless of how far in advance you book.
