Everything you need to know about our flight time calculator
We calculate the great-circle distance between two airports using the haversine formula, then divide by an average cruise speed of 850 km/h. We add 30 minutes of overhead for takeoff, climb, descent, and landing to provide a realistic estimate.
Our estimates are typically within 10-15% of actual flight times. Real flight times can vary based on wind conditions, flight path routing, airspace restrictions, and the specific aircraft used. Non-stop flights will be closest to our estimates.
Key factors include jet stream and wind patterns (flights westward are often longer), air traffic routing, weather diversions, the type of aircraft, and whether the flight is non-stop or has layovers. Our calculator shows non-stop estimates.
Our database includes 3,000+ airports worldwide sourced from OurAirports, covering all major international airports and medium-sized regional airports. Airport coordinates are used for precise distance calculations.
Yes, our flight time calculator is 100% free to use. No sign-up required. Calculate as many routes as you like with no limits.
Planning a trip as a digital nomad means juggling time zones, layovers, and jet lag. Our flight time calculator gives you instant estimates of flight duration and distance between any two airports in our database of 3,000+ worldwide.
Unlike basic distance tools, our flight duration estimator accounts for real-world factors by using the great-circle distance (the shortest path over the Earth's surface) and adding takeoff and landing overhead. Whether you're flying from Seoul to Bangkok, New York to London, or Los Angeles to Sydney, you get a realistic estimate in seconds.
Combine our flight time calculator with the timezone converter and cost of living calculator to make informed decisions about your next destination. Every route page includes timezone differences, related routes, and direct links to flight deals.
