On the Sunday after Thanksgiving last year, November 30, 2025, TSA officers screened 3.13 million people, the most the agency had ever processed in a single day. It was the third straight year that the Sunday after the holiday set the record, The Points Guy reported. Airlines for America had forecast that U.S. carriers would fly more than 31 million passengers across the eleven-day holiday period, which it called "an all-time high," in its November 20 outlook.

Thanksgiving 2026 falls on Thursday, November 26, about two months away, and the data on when to buy a seat for it points to a window that opens on Monday. The harder part of this year's calculation sits on the other side of the ledger. Jet fuel prices, trimmed schedules and a December funding deadline all favor travelers who commit early.

The short answer for holiday flyers is to aim for late October for Thanksgiving and the first days of November for Christmas, and to lean earlier rather than later within those ranges this year. What follows is the reporting behind that timing, plus the fees and rules that have changed since last December.

What Five Years of Google Flights Data Show

Google analyzed its flight pricing data from 2021 through 2025 and published the results on September 9 of last year. For Thanksgiving, "the lowest prices have been 35 days before departure," wrote James Byers, a group product manager for Search, in the Google blog post, with the lowest range running from 24 to 59 days out. For a Thanksgiving Day departure this year, that range stretches from September 28 to November 2, and the 35-day mark lands on Thursday, October 22.

Google found the lowest prices about 51 days before departure, within a range of 32 to 73 days. For a December 25 flight, that window runs from October 13 through November 23, with a low point near Wednesday, November 4. The same analysis found that Tuesday was the cheapest day to book, although only 1.3 percent cheaper than Sunday. Flying Monday through Wednesday instead of over the weekend saved about 13 percent, and accepting a connection instead of a nonstop saved about 22 percent.

These are historical patterns rather than a forecast, and Google has not yet published a 2026 edition. The best time to book Thanksgiving flights has also been a moving target, since booking windows have compressed since the pandemic. The Hopper 2025 Holiday Travel Shopping Index found that bookings made within two weeks of travel rose from 23 to 27 percent for Thanksgiving and from 22 to 26 percent for Christmas.

2026 Fares Are Already Running Ahead of Last Year

The early price signal for this season points up. "Right now, new data from TPG's partner, Points Path, shows cash fares have been running between 9% and 13% year-over-year for Thanksgiving travel searches in the past few weeks," Clint Henderson wrote in a September 2 guide. "Christmas fares are ranging between 12% and 18% higher," he added, with international holiday fares up 16 percent and a warning that "we expect prices to start climbing after Labor Day."

Those figures track searched fares rather than tickets sold, and they may soften if demand cools. Hopper's lead economist Hayley Berg, quoted in the same guide, cautioned against any single booking rule. "The reality is prices change so often and depend on the route, the travel dates, etc., that there isn't one day that guarantees you the best price," she said.

Her colleague Lindsay Schwimer pointed to the lever travelers control most directly. "Flying midweek can save you nearly $100 off your ticket," she said, and "we always recommend booking the first flight of the day, not only to avoid delays and cancellations but also in terms of price." Expedia's 2026 Air Hacks report, which covers the full year rather than the holidays, found August fares 29 percent cheaper than December's.

Airlines Are Trimming the Fourth Quarter

At the Morgan Stanley Laguna Conference on September 16, executives from American, United and Southwest all signaled fourth-quarter capacity adjustments. Jet fuel reached $4.51 a gallon for the week ending September 18, about 80 percent above a year earlier, Travelers Today reported.

"If fuel prices remain as high as they are right now, I think that that's going to require some adjustments in terms of our capacity planning as we take a look into the future," said American chief executive Robert Isom. United chief financial officer Michael Leskinen framed his airline's approach bluntly: "We are not flying to maximize market share. We're flying to maximize profitability and free cash generation."

Southwest's chief financial officer Tom Doxey described the same instinct. "If fuel is higher-for-longer, I think it's a natural response that you trim some of that capacity off," he said. The same report said United had already cut unprofitable December flights and American had suspended its Cleveland and Pittsburgh routes to Los Angeles. Moneywise, citing Reuters, reported that Southwest roughly halved its planned growth for the year.

Fewer seats against steady holiday demand is the combination that tends to erase late bargains. A traveler who waits for a November fare drop on a route that has lost a daily frequency may find the remaining flights priced for the people who have no choice.

The December 11 Deadline Holiday Flyers Should Watch

The government is funded through Friday, December 11, under a stopgap signed September 2, which the House approved 370 to 48, NPR reported. That date falls two weeks before Christmas, and air traffic controllers and TSA officers are among the federal workers expected to stay on the job without pay when funding lapses.

Airlines have lobbied for a fix. "Congress needs to pass legislation so that air traffic controllers, TSA officers and CBP agents are paid during future shutdowns, ensuring operational stability as well as the safety and security of our airspace," said Airlines for America chief executive Chris Sununu. Controller staffing remains a separate pressure point. A September 4 letter from Senators Tammy Duckworth and Dick Durbin to FAA Administrator Bryan Bedford quoted the agency's own warning that "chronic use of overtime leads to fatigue, controller burnout and ultimately loss of retention."

What Changed at the Checkpoint and the Refund Desk

Travelers without a REAL ID now face a fee that did not exist last Thanksgiving. Since February 1, 2026, passengers who arrive without a REAL ID or other acceptable identification can pay $45 in advance for TSA ConfirmID. The identity check can take up to thirty minutes at the checkpoint, according to TSA's January 15 announcement. A February 5 update said one payment covers ten days of travel, so a family flying out the Saturday before Thanksgiving and home the following Sunday would be covered on both legs.

The Department of Transportation's April 2024 rule requiring automatic cash refunds for canceled or significantly changed flights remains in force. DOT has paused enforcement through July 7, 2027 only for cases in which an airline renumbers a flight without a significant schedule change, while it revisits how a cancellation is defined.

Our earlier guide to pricing a real fare after the fee disclosure rollback walks through how to compare total trip cost. Travelers holding miles should weigh the changes we covered in this year's loyalty economics before assuming an award seat is the bargain.

A Holiday Booking Plan for 2026

Travelers with fixed Thanksgiving dates can set price alerts this weekend and plan to buy in October. The 24-to-59-day window opens Monday, and the fare trend is already running above last year. Flying on the holiday itself, on the Tuesday before, or returning on Monday, November 30 instead of the Sunday after keeps travelers off the peak days that set last year's record.

For Christmas flights 2026, the historical low arrives in early November, and Hopper's advice from last season to book before Halloween remains the more conservative target given the capacity cuts. International itineraries, which Points Path shows running 16 percent higher, reward the earliest commitment of all.

A fare that allows free changes, booked directly with the airline so the refund rule applies cleanly, protects against both the December 11 deadline and the schedule changes that come as carriers finalize winter flying. Last year's record Sunday belonged to people flying home on the most expensive day of the season, and the 2026 calendar puts that Sunday on November 29.
