In the US, taxi time is included in flight time only if the taxi time was incidental to an intended flight. Taxiing only for the purpose of moving the aircraft on the ground does not count. Otherwise, the FAA does not strongly nor strictly define flight time.

The answer depends on whether you are a pilot or a passenger. For pilots, according to FAA and EASA regulations in 2026, taxiing is absolutely considered part of "Flight Time." It is defined as the moment the aircraft first moves under its own power for the purpose of flight (often called "block-to-block" time). This is crucial for pilot logbooks and duty-hour limitations. However, for passengers and airline marketing, the "Flight Duration" usually refers to the time from takeoff to touchdown ("air time"). This is why a flight might be listed as 2 hours, but you are actually on the plane for 2.5 hours. In 2026, with the rise of electric air taxis (eVTOLs) in cities like Dubai and New York, the distinction is becoming even more important, as these vehicles spend significantly less time taxiing than traditional jets. Regardless of the definition, you are legally required to follow all crew instructions and remain seated with your belt fastened from the moment the "pushback" begins until the aircraft reaches the gate at your destination.
