FTCfly is a free, independent tool that estimates how long a flight between two airports should take. You get the great-circle distance, a realistic time estimate, and the exact local time you would land at the other end.
Why I made this
Hi, I'm Lokesh. Most "flight time" answers I found online were either a single number with no explanation, or hidden behind a wall of booking ads. I wanted something simpler. FTCfly shows you how it gets to the number, it is upfront that the figure is an estimate, and it adds the things I actually wonder about before a trip: what time I land locally, how big the time-zone jump is, how rough the jet lag might be, and roughly how much CO₂ the flight burns.
How it actually works
For two airports, the tool measures the shortest distance over the curved Earth (the great-circle distance) from their coordinates, divides it by an average cruise speed of about 800 km/h, and adds around 30 minutes for taxiing, take-off, climb, descent and landing. It then converts the arrival into the destination's local time using the full IANA time-zone database, so daylight saving and "you land the next day" are handled for you.
Because it uses a straight-line distance and an average speed, the number is an estimate, usually within about 15% of the real schedule. Winds (mainly the jet stream), the exact route air-traffic control gives the flight, the aircraft type and any connections all push the real time around. I explain the full method on the disclaimer page.
How FTCfly stays free
I run this on my own. Some outbound links, for things like eSIMs, travel insurance or airport transfers, may be affiliate links that earn a small commission if you buy through them, at no extra cost to you. That never touches the flight-time numbers, which are pure maths. The disclaimer and privacy policy spell this out.
