U.S. Clocks Fall Back November 1: Flight Times and American Airlines Check-In Alert
November 1, 2026 — Travel advisory. Most of the United States returns to standard time at 2 a.m. local time on Sunday, November 1. For travelers with flights, airport transfers or early-morning connections, the important detail is that the clock change happens at different moments in different time zones. Travelers should confirm the local time shown on each booking rather than simply adding an hour to a departure time.
What changes on November 1?
According to the National Institute of Standards and Technology (NIST), at 2:00 a.m. local daylight time the clock moves back to 1:00 a.m. local standard time. That repeated hour can make overnight travel plans look confusing, particularly if a traveler is comparing a phone calendar, an airline itinerary and a hotel or car-rental confirmation.
The change does not apply everywhere. Hawaii and most of Arizona do not observe daylight saving time, while the Navajo Nation in Arizona does. Puerto Rico and several U.S. territories also do not change their clocks. The U.S. Department of Transportation oversees the country’s time-zone rules.
American Airlines has a special check-in notice
American Airlines is displaying a notice for people traveling on November 1, 2026. The airline advises those customers to wait until 23 hours before scheduled departure to check in during this particular time change. This is a date-specific notice: it should not be confused with the airline’s general online check-in guidance, which ordinarily says check-in opens 24 hours before departure.
If your flight is operated by American Airlines today, follow the live notice in your reservation or app. If another carrier operates your flight — including a codeshare flight — use that operating carrier’s instructions rather than assuming the American Airlines notice applies.
Are ticket times local?
Yes, airline itineraries generally express a departure in the departure airport’s local time and an arrival in the arrival airport’s local time . JetBlue explicitly explains this on its flight-status help page. That distinction is essential for international trips and connections involving places that change clocks on different dates or not at all.
A 6:00 a.m. departure is still a 6:00 a.m. local departure; do not manually change the scheduled time printed on your airline’s current itinerary. Instead, refresh your booking in the airline’s app or website and verify the flight number, travel date, terminal and boarding deadline.
Five checks before you leave
Open the live reservation. Confirm the scheduled departure and arrival times directly with the operating airline.
Check the airport’s time zone. Do this for both ends of a connecting trip, especially if Arizona, Hawaii or an international city is involved.
Review the check-in window. American Airlines has a November 1 notice; other airlines may have different instructions.
Confirm ground transportation. Recheck prebooked shuttles, rental-car pickup and hotel arrival arrangements, particularly around the repeated 1:00 a.m. hour.
Allow your normal airport buffer. The extra hour on the clock is not permission to arrive later than your airline’s advised check-in or security deadline.
