TopToolsAiWork out actual flight duration from your ticket's departure and arrival times, correctly accounting for the time zone difference between the two airports. A flight departing Karachi at 2:00pm PKT and arriving Dubai at 4:30pm UAE time looks like a 2.5-hour trip on the ticket, but after adjusting for the 1-hour time difference between the two zones, the actual flight duration is closer to 3.5 hours.

Frequently asked questions
Where do I find the UTC offset for a timezone?
Search "[city name] UTC offset" — e.g. Pakistan is UTC+5, New York is UTC-5 (or UTC-4 during daylight saving).
Does it handle overnight flights automatically?
It adds 24 hours automatically if the raw result comes out negative, so overnight flights are handled correctly.
Why do I need timezone offsets instead of just subtracting clock times?
Departure and arrival times are in different local timezones — subtracting the clock times directly without adjusting for that gives the wrong duration.
Where do I find my flight's departure and arrival times?
Check your ticket or boarding pass — both times are usually shown in local time for each respective airport.
