Layover Duration
Find the exact time between two connecting flights.
About Layover Duration
Both legs are converted to minutes past midnight; if the departure clock is earlier, a full day is added to span midnight. A layover that looks like 45 minutes of flight-time math can be an overnight when the arrival is after midnight.
