As of August 2026, the best time to book Christmas flights is roughly 32 to 73 days before departure, with the lowest average fares around 51 days before departure. Mid-October through mid-November is the prime booking window for 2026. Flying on Christmas Day itself is almost always significantly cheaper than surrounding dates.
How far in advance should I book Christmas flights?
NerdWallet's August 6, 2026 report, based on four years of Google Flights data, found the lowest fares around 51 days before departure. The Points Guy's June 9, 2026 analysis puts the usual range at 32 to 73 days before the holiday. For Christmas 2026, that means mid-October through mid-November.
December is one of the most expensive months to fly. NerdWallet's same report lists August, September, and January as the cheapest months. If you're flying over the holiday, start checking before mid-October. You don't need to search every day. Watch fares from your home airport and book when your route drops.
Do flight prices go down on Christmas Day?
Yes. Most travelers want to arrive before December 25, so airlines price the holiday itself lower. The Points Guy's June 9, 2026 analysis says flying on Christmas Day and Thanksgiving Day "is almost always significantly cheaper than the surrounding days." If your schedule allows, use December 25 as a departure or return date.

Do Christmas flight prices drop in the weeks before departure?
Generally no. Christmas fares usually rise as departure approaches because cheap fare classes sell out first. Going, cited by NerdWallet on August 6, 2026, warns prices rise as the flight date nears because demand spikes. Jack's Flight Club notes occasional flash bargains two to three weeks before departure, but they're unpredictable and not a plan.
Our explainer on why flight prices change covers the mechanics behind that pattern.
Is the booking window different for international Christmas flights?
Yes. Going, cited by NerdWallet on August 6, 2026, recommends booking domestic cash fares 1–3 months ahead and international cash fares 2–8 months ahead. For Christmas 2026, international travelers should start monitoring earlier than domestic travelers and aim to book by mid-November at the latest. Exact international timing data is thinner than domestic, so err earlier and track fares from your departure airport.
FAQ: Christmas 2026 flight booking questions
Is it cheaper to fly on Christmas Eve or Christmas Day?
Christmas Day is typically cheaper than Christmas Eve because demand shifts away from the holiday itself. The Points Guy's June 9, 2026 analysis reports flying on Christmas Day is almost always significantly cheaper than surrounding days. If you can travel on December 25, do it.
How far ahead should I book international flights for Christmas 2026?
Going's general guidance, cited by NerdWallet on August 6, 2026, is 2–8 months for international cash fares, versus 1–3 months for domestic. For Christmas 2026, start monitoring by early October and aim to book before mid-November (as of August 2026).
Are there last-minute Christmas flight deals?
Rarely. Christmas fares generally climb as departure nears; the known range is 32–73 days before departure. A few flash bargains can appear 2–3 weeks before departure, but catching them requires fare alerts, not hoping for a price drop.
What is the cheapest day to fly around Christmas?
Christmas Day itself is almost always significantly cheaper than surrounding days, including Christmas Eve. If your schedule allows, departing or returning on December 25 can lower fares.
Should I book Christmas 2026 flights now or wait?
As of August 2026, the lowest prices are still ahead. The 32–73-day window starts around mid-October. Unless you see an exceptional fare, set up tracking now and plan to book in that window.
