Cheap Flights for December Holiday Travel 2026: 12 Tips to Save

Why December Flights Are So Expensive

December is the most expensive month of the year for flights. The reason is simple supply and demand. Everyone wants to fly home for Christmas or escape somewhere warm for the holidays. Airlines know this and price accordingly. Average December fares are 30 to 50 percent higher than October fares for the same routes.

The most expensive travel dates are December 22 to 24 (Christmas outbound) and December 26 to 27 (Christmas return). New Year’s Eve (December 31) and New Year’s Day (January 1) are also expensive. If you can avoid these specific dates, you can save 20 to 40 percent.

Cheapest Days to Fly in December

Based on 3 years of Google Flights data, here are the cheapest days to fly in December 2026:

• December 1 to 14: The cheapest two weeks of the month. Fly before the holiday rush. Fares are 30 to 40 percent lower than Christmas week.
• December 25 (Christmas Day): Nobody wants to fly on Christmas. Airports are empty. Fares drop 20 to 30 percent from December 24. If your family can celebrate Christmas on December 26, fly on the 25th.
• January 1 (New Year’s Day): Same principle. Nobody flies on January 1. Fares drop 25 to 35 percent from December 31.
• Tuesday and Wednesday: Mid-week flights are 15 to 20 percent cheaper than weekend flights throughout December.

The most expensive days: December 22, 23, 26, 27, 30, and 31. Avoid these if at all possible.

When to Book December Flights

The booking window for December flights is earlier than most months. Here is the timeline:

• September to early October: Best time to book. Fares are at their lowest. Airlines have not yet raised holiday prices.
• Mid October to mid November: Still reasonable, but fares are rising 5 to 10 percent per week.
• Late November: Prices are climbing fast. You will pay 20 to 30 percent more than September rates.
• December (last minute): Expect to pay 50 to 80 percent more. Last-minute December flights are brutal. A $250 domestic flight costs $450 to $600.

I booked my Christmas 2025 flight on September 15 for $280 round-trip. The same flight cost $520 on December 10. The lesson: book in September.

12 Tips to Save on December Flights

• 1. Book in September or October. This is the single most important tip. September rates are 30 to 50 percent lower than December rates.
• 2. Fly on December 25 or January 1. Nobody wants to fly on holidays. Airports are empty, fares drop 20 to 35 percent.
• 3. Fly on Tuesday or Wednesday. Mid-week flights are 15 to 20 percent cheaper than weekends.
• 4. Use Google Flights price tracker. Set up alerts for your route 3+ months ahead. Google emails you when the price drops.
• 5. Check nearby airports. Newark (EWR) can be $100 cheaper than JFK. BWI can be $80 cheaper than DCA.
• 6. Book one-way tickets separately. Sometimes two one-ways on different airlines are cheaper than a round-trip.
• 7. Use airline miles. December is peak season, so miles rates are high. But if you have a flexible miles program, it can still save you $300+.
• 8. Consider budget airlines. Spirit, Frontier, and Allegiant have December fares as low as $39 one-way. Just add luggage fees to the math.
• 9. Fly into secondary airports. London Stansted instead of Heathrow. Paris Beauvais instead of CDG. Smaller airports have lower landing fees and cheaper flights.
• 10. Be flexible with dates. Use Google Flights calendar view. Shifting your departure by 1 day can save $100 to $200.
• 11. Book directly with the airline. OTAs (Expedia, Priceline) sometimes have lower fares, but they make changes and cancellations much harder. Pay the extra $10 to book direct.
• 12. Use a travel credit card. Chase Sapphire Preferred, Amex Gold, and Capital One Venture cards offer travel credits and points that can offset December fares.
