Is Thanksgiving travel more expensive this year?

Already booked?

• Watch the price after you book: on 24% of the flights Axel booked departing November 2026, the same fare later dropped at least 5% and $25 [6]. Most of those trips haven't flown yet, so the share can still rise.
• Within 24 hours of booking, if you booked at least 7 days before departure, you can cancel for a full refund and rebook at a lower price [10].
• On most standard (non-basic) fares from Delta, United, American and Southwest, you can change to the same flight at the lower price with no change fee; the difference usually comes back as airline credit.
• If you book with Axel, Axel watches the fare and claims the difference when the same fare drops: Members keep 100% of the saving, free users keep 75%.

How this guide was made

Fares are the lowest round-trip economy fares Google Flights showed in Axel's flight searches from May 6 to Oct 26, 2026, compared within the same routes so that a route's general price level doesn't count as a holiday effect. The cheapest-day figures compare departures on each day with the same routes' departures 15 to 28 days either side, at the same booking lead time; days with too few fares are left out. Crowd figures are TSA's daily checkpoint counts, 2019 and 2022 onward; delay figures are the Bureau of Transportation Statistics' on-time data. The booking window combines Axel's fares with the published studies cited, each of which measures something different (see the table).
