Flight Path Calculator
Calculate flight distance, duration, and view the route on an interactive map.
Airport-to-Airport Distance in Seconds
Pick two airports and this free calculator computes the great-circle distance between them — the shortest path over the Earth's surface — and estimates the flight time, all drawn on an interactive map.
Search a built-in airport database by name, city, or IATA code. The route arc, distance in miles and kilometers, and estimated travel time appear instantly.
Airport search with IATA codes
Find airports by name, city, or three-letter IATA code from the built-in database.
Interactive route map
The great-circle path is drawn on a zoomable map with the distance and estimated flight time shown alongside.
How it works
Distances are computed in your browser with the haversine formula; the interactive map loads public tile imagery from OpenStreetMap's servers. No account or uploads needed.
How to use
- Enter your departure airport (name, city, or IATA code).
- Enter your destination airport.
- Click Calculate to see the distance, route map, and estimated flight time.
Frequently Asked Questions
What is great-circle distance?
The shortest distance between two points on the Earth's surface — the path long-haul flights roughly follow, shorter than it looks on a flat map.
How is flight time estimated?
The tool divides the great-circle distance by a typical cruising speed; real flight times vary with wind, routing, and aircraft type.
Can I search by IATA code?
Yes. Three-letter codes like JFK, LHR, and DXB are recognized, along with city and airport names.
Is the tool free?
Yes, completely free with no signup.
