The Sweet Spot for Thanksgiving Flights
According to a recent holiday travel report from Google Flights, the average price of airline tickets tends to be at its lowest for domestic Thanksgiving trips 39 days before departure. That translates roughly to mid-October for most years. Google notes that the low-price booking range for domestic Thanksgiving travel is between 23 and 51 days prior to departure.
Average prices for Thanksgiving trips tend to be lowest 35 days before departure, versus 45 days in the 2024 analysis. The window has been gradually shifting, which signals that travelers are adapting and competition for seats is intensifying earlier in the season.
The Christmas and New Year’s Booking Window
As for Christmas travel, according to Google, prices have historically been lowest 51 days before departure, meaning the ideal time frame for booking Christmas flights is in late October. The low-price booking range for Christmas travel is between 32 and 73 days before.
Average prices for Christmas and New Year’s trips tend to be lowest 51 days before departure. That gives most travelers a reasonably generous runway, though it requires acting well before the season feels urgent. The best prices can be found when you book between October through mid-November.
Why October Is the Single Most Important Month for Holiday Booking
According to Google Flights’s recent report, October is the best time to book holiday flights. This holds for both major winter holidays, which makes October a genuinely pivotal month for anyone planning end-of-year travel. For the best deal on Thanksgiving and Christmas flights, you’ll want to book by the end of October, according to data released by Google Flights in 2024.
October is also the best time to book Christmas flights. Airfare for Christmas trips averaged $406 per round-trip ticket, and those prices were expected to fall by about $80 until reaching their lowest point in October. Waiting past November dramatically reduces your options at any reasonable price point.
How Much Money the Right Window Actually Saves
Expedia’s Holiday Travel Outlook reveals that booking by specific dates saves travelers real money, with data showing booking by October 28 for Thanksgiving and December 4 for Christmas can save travelers up to $140 on flights. Those are not marginal savings on a family trip.
Hopper says it’s possible to save more than $100 off peak airfare by flying on less popular dates before and after each holiday week during Thanksgiving and Christmas. The window and the departure date together form a two-part strategy, not a single trick.
The Day You Fly Matters Almost as Much as When You Book
The cheapest days to travel are still Monday through Wednesday, about 13% cheaper than flying over the weekend, according to a 2025 Google report. For domestic routes specifically, that discount gets even more pronounced. You can save 20% by flying on a Monday, Tuesday, or Wednesday versus a weekend.
Hopper puts specific numbers on it: flying midweek saves an average of $67 per ticket on domestic routes, $166 to Europe, and $126 to Asia. Flying on the holiday itself is another underused option. Going estimates that travelers can save about 15 to 30 percent per ticket, depending on the destination, by departing on the holiday itself.
The Expedia Data on “Book-By” Dates
Expedia’s 2025 Holiday Travel Outlook introduced specific book-by dates as a practical guide. Expedia data shows booking by October 28 for Thanksgiving, and October 25 for domestic Christmas flights, can save travelers up to $60, while international Christmas bookings by November 25 can save up to $140.
The cheapest day to depart for Thanksgiving is Monday, November 24, while Christmas Eve is the cheapest departure day for Christmas travel. On the return side, the data is equally specific: Sunday, November 30 for Thanksgiving returns, and New Year’s Eve for Christmas returns, tend to offer better prices than the alternatives. Knowing these dates in advance removes a lot of the guesswork.
Travelers Are Searching Earlier Than Ever Before
New data from Going reveals that travelers are searching for Thanksgiving and Christmas airfare more than two weeks earlier than last year as they look to stretch their budgets. Going notes that Americans are searching an average of 15 days earlier this year than they did in 2024, which could skew trends of years past.
This behavioral shift matters because it creates earlier price pressure on popular routes. When more travelers compete for seats in September, fares on key corridors can firm up sooner. Starting your fare monitoring in late August or early September for Thanksgiving, and in early October for Christmas, is now a reasonable baseline rather than an overcautious move.
Why the Old “Book on a Tuesday” Rule No Longer Applies
For years, travelers operated on the belief that booking on a Tuesday afternoon unlocked hidden airline discounts. The data no longer supports that. Hopper confirms that algorithms reprice fares more than 200 times daily, which has essentially eliminated the old Tuesday booking rule.
The Hopper 2026 dataset shows the day-of-departure effect is roughly five times stronger than the day-of-purchase effect. NerdWallet and AmEx Global Business Travel both report that day-of-week booking variation is typically less than 3 percent. The big lever is the booking window, not the booking weekday. That is a meaningful shift in how travelers should think about their strategy.
How Price Prediction Tools Have Changed the Game
Google Flights, Hopper, and Kayak all use historical pricing data to predict where fares are headed. Google Flights specifically tells you whether a price is “low,” “typical,” or “high” for that route, and shows the price history for the past 60 days. These tools have made the booking process considerably more transparent than it once was.
Hopper uses historical data, proprietary algorithms, and artificial intelligence programming to make its price predictions, which it claims are 95% accurate for flights up to a year in advance. Hopper goes a step further and predicts whether to buy now or wait. Used alongside Google Flights’ route price history, these tools take a lot of the anxiety out of a genuinely complex decision.
What the Data Says About Flexibility and Off-Peak Travel
On average, travelers saved 32%, or about $100 per ticket, off airfare when traveling in the first two months of the year instead of in March and April, peak spring break travel months. Domestic travelers also saved 40%, or an average of $150 off airfare, by shifting trips from peak summer months to September or October. Holiday pricing follows similar logic: even a one-day shift can matter.
If you have the flexibility to work remotely or take time off around the holidays, it could save you $100 or more to fly on lower-demand days. Many U.S. airlines offer different levels of award pricing based on demand, so you might be able to spend fewer points if you fly on the cheaper days. For points travelers, the departure date strategy applies just as much as it does for those paying cash.
A Practical Timeline That Puts It All Together
Working backward from the data, a clear seasonal calendar emerges. For Thanksgiving, start monitoring fares in late August or early September. Prices for Thanksgiving flights generally rise in mid-October, making early September an ideal time to start watching fares and lock in a deal. For Christmas, the monitoring window opens in late September, with the ideal purchase landing in mid to late October.
For Thanksgiving, the best booking window is around 35 days out, within a 24 to 59 day range according to Google. For Christmas and New Year’s, the best booking window is around 51 days out, within a 32 to 73 day range. Print that calendar, set a fare alert, and treat the booking date like any other travel deadline worth keeping.
