This flight time calculator estimates how long a flight takes from the distance and the aircraft’s average ground speed. Enter both values above to get the duration in hours and minutes.
Formula
Flight time = Distance ÷ Average speed
Example
3,000 miles at 500 mph: 3,000 ÷ 500 = 6 hours.
Add time for taxi, climb, and descent, and adjust arrival for time-zone differences.

Frequently Asked Questions
How do I calculate flight time?
Divide the flight distance by the average ground speed. A 3,000-mile flight at 500 mph takes about 6 hours in the air.
Does flight time include taxi and delays?
No. This is airborne time. Add taxi, climb, descent, and any holding for total gate-to-gate time.
How do time zones affect arrival?
Flight time is the same, but the clock at arrival shifts by the time-zone difference between origin and destination.
