How It Works

How to Estimate Flight Time

Divide the distance by the average cruising speed of the aircraft.

Formula

Flight Time = Distance / Speed

Commercial jets cruise at 500-575 mph. Add time for takeoff, landing, and any layovers.

Worked Example

2,500-mile flight at 550 mph with no layover.

distance_miles = 2500avg_speed = 550layover_hours = 0
  1. 01Air time = 2,500 / 550 = 4.5 hours
  2. 02Total travel = 4.5 + 0 = 4.5 hours
  3. 03In minutes = 4.5 x 60 = 273 minutes
