How to use this tool

  1. Enter your layover duration in minutes (found on your itinerary).
  2. Enter the minimum connection time for your airport and route type.
  3. The calculator shows the layover in hours and minutes and how much buffer you have above the minimum.

A 45-minute layover that exactly meets the minimum connection time provides zero buffer for delays — this is generally considered too risky.

Frequently asked questions

How long of a layover do I need?
For domestic connections at the same airport, 45–60 minutes is typically sufficient. For international connections or connections requiring a terminal change, allow 90–120 minutes minimum.
What happens if my layover is too short?
If your flights are on the same booking, the airline is responsible for rebooking you if you miss the connection due to a delay. If booked separately, you bear the risk.
