Quick answer
Flight time is distance ÷ cruise ground speed, plus roughly 30–40 minutes for taxi, climb, descent and approach on a typical jet flight.
Time = distance ÷ ground speed + fixed overhead

Frequently asked questions
Why is the eastbound flight faster?
The jet stream blows west to east, so eastbound flights ride a tailwind of 50–150 mph while westbound flights fight it.
Does the schedule include padding?
Yes — airlines pad published times by 10–20 minutes to protect on-time statistics, so scheduled duration is usually longer than the real flight.
What do I need to enter into the Flight Time Calculator?
Just 4 values: route distance, cruise ground speed, head (−) or tail (+) wind, taxi, climb and descent allowance. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Flight Time Calculator work out the answer?
Flight time is distance ÷ cruise ground speed, plus roughly 30–40 minutes for taxi, climb, descent and approach on a typical jet flight. It applies the formula Time = distance ÷ ground speed + fixed overhead and shows the working so you can check each step by hand.
Is the Flight Time Calculator free, and do I need an account?
It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
