How to use this calculator
Divide the flight distance by the effective airspeed (aircraft cruise speed minus headwind, or plus tailwind). Add 30 minutes standard taxi/ground time for total journey time. Apply the time-zone difference to find the local arrival offset.
- 1
Enter the flight distance in kilometres between your origin and destination airports.
- 2
Select the aircraft type that matches your flight — this sets the cruise speed automatically.
- 3
Enter the headwind (positive) or tailwind (negative) and the time-zone difference, then read your estimated flight time and local arrival shift.
Frequently asked questions
How is flight time calculated?
Flight hours = distance ÷ (cruise speed − headwind). The cruise speeds are fixed in the code: narrow-body 850 km/h, wide-body 905, regional jet 780, turboprop 550 and supersonic 2,100. Your headwind is subtracted from the speed; a negative headwind counts as a tailwind and is added. For 5,000 km on a narrow-body with no wind: 5,000 ÷ 850 = 5.88 h, shown as 5h 53m.
Does the tool work out the distance between two airports?
No. You enter the distance in kilometres yourself. The tool has no airport database and does not calculate great-circle distance, so use the route distance from a map or the airline and remember that flown routes are often longer than the straight line.
What does the "total journey time" add?
A flat 30 minutes added to the flight time, which the tool treats as a combined taxi and ground allowance. It does not change with distance, airport size or time of day. A 600 km turboprop flight with a 40 km/h headwind shows 1h 11m of flight and 1h 41m in total.
What does "local arrival shift" mean?
It is the total journey time plus your time zone difference, giving how much later or earlier the destination clock reads at landing than the origin clock read at take-off. Flying 5,570 km on a wide-body with a 60 km/h tailwind, to a zone 5 hours behind, shows 1h 16m later: 6h 16m in the air and on the ground minus 5 hours.
How should I enter headwind and tailwind?
A headwind is a positive number and a tailwind is negative. The effective speed cannot fall below 1 km/h, so an extreme headwind larger than the aircraft speed will give an absurd result. Wind varies by altitude and route, so a single average number is only a rough input.
Does the result match a published airline schedule?
Not exactly. Airlines publish block times that include taxi, routing, air traffic control and seasonal wind patterns, so a scheduled time can differ from this estimate by many minutes. Use the tool for planning and comparisons, and rely on your ticket for the real times.
Can it handle connecting flights or stopovers?
No. It models one non-stop segment. For a connection, run each leg separately and add your layover time yourself. The supersonic entry is a hypothetical speed for comparison; it should not be read as an indication of a service you can book.
Flight time calculator: distance, cruise speed and wind
The calculation in plain terms
You supply a distance in kilometres, choose one of five aircraft types, and optionally enter a wind speed and time zone difference. The tool subtracts the headwind from the aircraft’s fixed speed, divides the distance by it, and shows the result in hours and minutes. A flat half hour is then added for ground time. The tool rounds to the nearest whole minute before splitting hours and minutes, so a value such as 2h 60m never appears.
| Aircraft type | Speed (km/h) | Hours for 1,000 km, no wind |
|---|---|---|
| Narrow-body (737, A320 class) | 850 | 1h 11m |
| Wide-body (777, A380 class) | 905 | 1h 06m |
| Regional jet (Embraer, CRJ class) | 780 | 1h 17m |
| Turboprop | 550 | 1h 49m |
| Supersonic (hypothetical) | 2,100 | 0h 29m |
Worked examples
Each row comes from running the calculator with the inputs listed.
| Inputs | Flight time | Total with 30 min ground | Clock shift |
|---|---|---|---|
| 5,000 km, narrow-body, no wind | 5h 53m | 6h 23m | 6h 23m later |
| 5,570 km, wide-body, 60 km/h tailwind, zone -5 h | 5h 46m | 6h 16m | 1h 16m later |
| 600 km, turboprop, 40 km/h headwind | 1h 11m | 1h 41m | 1h 41m later |
| 900 km, regional jet, zone +1 h | 1h 09m | 1h 39m | 2h 39m later |
What wind does to a long flight
Wind matters more on long flights because the difference accumulates. The 5,570 km wide-body run with a 60 km/h tailwind takes 5h 46m, whereas the same run with no wind would take about 6h 09m. A 40 km/h headwind on a slow turboprop lifts the 600 km trip from 1h 05m to 1h 11m. Remember that real winds vary by altitude and hour, and jet-stream routing is not modelled. The wind entry is a single average over the whole route.
Reading the clock shift
The time zone field is destination minus origin, in hours. A positive number moves the arrival clock reading later, a negative one earlier. If the difference is large and negative, such as -8 on a short flight, the label reads earlier, meaning the destination clock at landing shows a time before the one you left on. The tool does not handle date lines or daylight saving changes; enter the actual hour difference for your travel date.
Limits to keep in mind
The estimate ignores climb and descent profiles, holding patterns, detours around weather or restricted airspace, and the specific aircraft model. It also assumes a constant speed for the whole route. For ticketing, check the airline’s timetable. For comparing two aircraft types over the same distance, or seeing roughly how much a headwind costs, the tool gives a quick ballpark. It is also handy for checking whether a published schedule looks plausible: if a 5,000 km flight is listed at 4 hours on a narrow-body, something is off, and a connection or a faster aircraft is probably involved. Enter distances as kilometres only; the tool does not convert miles.
