Estimate how long a flight will take from the distance between two airports and the aircraft cruise speed. Enter the great circle distance in miles or kilometers and a typical cruise speed, and this tool returns the pure air time, then adds a realistic buffer for taxi, takeoff climb, and descent so the number is closer to the gate-to-gate time airlines quote. A jet cruises around 500 to 560 miles per hour, while a turboprop is much slower, so you can plug in a speed that matches the route. This is handy for planning connections, guessing arrival times across schedules, or sanity checking a booking. It ignores wind and routing detours, so treat it as an estimate.
