How Axel worksWhen to book flights: every holiday and travel period
Updated October 26, 2026 · Data: Axel · How this guide was made
Book U.S. domestic flights about 1 to 3 months ahead and international flights 2 to 6 months ahead; for holidays, book inside each holiday's window (Thanksgiving about 3 to 8 weeks out, Christmas about 5 to 10 weeks), and don't wait for the final two or three weeks, when fares climb every week. The calendar below gives the booking window for every holiday in 2026 and 2027, and each guide has the cheapest and busiest days, delays and what to do if the price drops.
