US airlines expect 29 million Thanksgiving travelers, American schedules 7,021 flights on November 29

Quick summary

US airlines expect to carry close to 29 million passengers between November 20 and November 30, 2026, with November 29 and 30 the heaviest days of the window. American Airlines alone has 7,021 flights scheduled on November 29 — its busiest day since the pandemic — and United Airlines expects about 600,000 travelers that date.

The crunch lands on the trip home, not the trip out. Hopper puts the average November 29 domestic round-trip fare at $604, well above off-peak pricing for comparable flights.

Thanksgiving 2026 is shaping up as the biggest single test of US domestic aviation since 2020 — and the pressure point is the trip home, not the trip out.

Nearly 29 million passengers are forecast to fly between November 20 and November 30, according to Airlines for America, the US airline trade group. That is roughly 2.6 million people a day, and carriers have padded their schedules with about 38,000 extra seats daily compared with the same window last year.

The busiest single date is November 29. American Airlines has 7,021 flights scheduled that Sunday, its heaviest day since the pandemic, with as many as 1,130 aircraft airborne at once by midday. United Airlines expects roughly 600,000 passengers on the same date.

For travelers, the read is blunt: the outbound is manageable, the return is not. Anyone flying home through Los Angeles International, John F. Kennedy, Atlanta or Chicago O’Hare on November 29 or 30 should plan for the year’s worst security lines — and should know that moving a return by 24 hours changes both the crowd and the price.

What the November 29 schedule actually looks like

The trade group’s November 10 forecast projects close to 29 million passengers across the 11-day window that opens November 20 — roughly 2.6 million a day. Compared with last year’s holiday, the industry is flying about 38,000 more seats every day.

American Airlines and its regional partners have scheduled roughly 85,000 flights for more than 8 million passengers between November 19 and December 1. That is about 4% more departures than last Thanksgiving. Its heaviest date is November 29, when 7,021 flights are on the books. By midday, up to 1,130 aircraft are expected to be airborne at once.

United Airlines expects more than 6.6 million passengers over the same 13-day stretch, with its outbound peak on Friday, November 20, at more than 540,000 travelers, before the return wave crests near 600,000 on November 29.

Adding seats is the easy part.

The constraint on November 29 is not how many aircraft are flying; it is how many people can clear a checkpoint and turn at a gate inside the same four-hour window.

TSA has never screened more people in a single day than on November 30, 2025, when 3,134,613 travelers passed through checkpoints, according to the agency’s daily volume records. That is a benchmark, not a 2026 projection. It does, however, show how sharply post-holiday demand spikes. Across the seven days around last Thanksgiving, LAX led all airports at about 689,000, ahead of JFK (647,000), Atlanta (603,000) and O’Hare (598,000).

Fares track the same curve. Hopper puts the average domestic round-trip fare for a November 29 return at $604. Air Traveler Club’s fare tracking occasionally flags temporary drops on shoulder dates around the holiday, though the peak-day premium rarely softens this close to departure.

Why 38,000 extra seats don’t fix the Sunday crunch

The industry’s response to record demand has been to add capacity ahead of a concentrated peak rather than to spread travel across the calendar. That is a rational commercial move — and a limited operational one.

Airlines can schedule extra frequencies in a matter of weeks. Airports cannot add security lanes, apron space or curb capacity on the same timeline, which is why a forecast and the experience on the ground rarely match.

The pressure is also uneven. Even with seats added systemwide, the crowding concentrates at the four airports that led last year’s rankings — a traveler departing a mid-size hub may notice little change, while someone connecting through O’Hare on November 30 faces a genuinely difficult day.

Watch the weather, too. A single winter storm across the Midwest or Northeast on November 29 would strand aircraft in the wrong cities for days, and there is no spare capacity in the system to absorb it.

How to protect a Thanksgiving return

November 29 and 30 are the two most constrained travel days on the US calendar this year — the steps below are ordered by how much they actually reduce your exposure.

1. Shift the return if you can. November 28 or December 1 departures are measurably lighter; compare both directly on American’s flight status tool or United’s before committing.
2. Take the earliest departure you can tolerate. Checkpoint queues build through the morning; a 6 a.m. flight clears security before the wave arrives.
3. Add buffer time at LAX, JFK, ATL and O’Hare. Those four carried the heaviest checkpoint loads of last year’s holiday week.
4. Check status before leaving for the airport. Crew and aircraft rotations degrade through a peak day, and the first sign is usually a gate or time change.

Watch: TSA’s daily checkpoint counts for November 29–30. If they track toward the 3.13 million record, expect the same crush on the way home.
