Flight Time Conversion Mathematics
When flying west-to-east (e.g., New York JFK to London LHR), your destination is 5 hours ahead. A 7-hour flight departing New York at 8:00 PM EST lands at 3:00 AM EST, which corresponds to 8:00 AM GMT (local London time) the next morning.

Frequently Asked Questions
How do time zone changes affect flight arrival times?
Flight arrival times are always displayed in the local time zone of the destination airport. Subtracting origin time from destination arrival time requires factoring in both flight duration and net time zone offset.
What is the formula for calculating international flight arrival time?
Local Arrival Time = Departure Local Time + Flight Duration + Net Time Zone Offset (Destination Zone Offset minus Origin Zone Offset).
