Need to use Flight Time & Layover Calculator right now?
A multi-leg itinerary with connecting flights makes it surprisingly hard to figure out your total time in the air versus time spent waiting in airports — especially once each flight crosses time zones, since simple clock-time subtraction between departure and arrival stops making sense.
Enter each flight's departure and arrival (local time)
Flight 1

Times are treated as entered (local to each airport) — enter departure/arrival exactly as shown on your boarding pass or itinerary.

About Flight Time & Layover Calculator
A multi-leg itinerary with connecting flights makes it surprisingly hard to figure out your total time in the air versus time spent waiting in airports — especially once each flight crosses time zones, since simple clock-time subtraction between departure and arrival stops making sense.
This calculator takes the departure and arrival date-time for each flight segment in your itinerary, computes the actual flight duration for each leg by comparing full timestamps (correctly handling time zone changes when you enter each time as shown on your boarding pass), and calculates layover time as the gap between one flight's arrival and the next flight's departure.
Add as many connecting flights as your itinerary needs, and see a full breakdown of every leg's flight time and every layover, plus your grand totals for time actually flying versus time spent on the ground between flights.
How it works
- Enter your first flight. Input its departure and arrival date and time.
- Add connecting flights. Add each additional flight leg with its own departure and arrival.
- Read the full breakdown. See each leg's duration, each layover, and your trip totals.
Examples
