Why the arrival time is confusing
Your ticket shows departure in the time of the city you leave and arrival in the time of the city you land in. Add a time difference, an overnight flight and a summer-time change in one country but not the other, and it is easy to tell the person collecting you the wrong day. This calculator does the sum with the official time-zone rules built into your browser, including daylight saving on the actual date of travel.
Where the flight time comes from
For an exact answer, type the flight duration printed on your booking or the airline's timetable. If you leave it blank, the tool estimates it from the straight-line distance between the two main airports, at an average of 800 km/h plus 30 minutes for take-off, climbing and landing. Real flights vary with winds, air routes and aircraft – flying east across the Atlantic is often an hour shorter than flying west – so treat an estimate as a guide only and always check your booking.
Worked example: London to Dubai, leaving at 09:00 on Saturday 14 November 2026, with a booked flight time of 6 hours 55 minutes. London is on UTC+0 in November and Dubai on UTC+4, so Dubai is 4 hours ahead. 09:00 + 6h 55m is 15:55 in London time, which is 19:55 on Saturday in Dubai. The airports are about 5,500 km (3,400 miles) apart in a straight line.
Stopovers
For a journey with a change of plane, type the total flying time of both flights and the waiting time at the connecting airport as the stopover. The result shows the whole journey from leaving to landing, in the destination's local time.
Tips for long-haul travel
- Share the arrival time with whoever is collecting you in their local time – the number this tool shows in large text.
- If you arrive the next morning, plan an easy first day; flying east usually causes more jet lag than flying west.
- Set your watch or phone to the destination time when you board.
- Use the time zone converter to plan calls home while you are away.
