Calculates the buffer time above the minimum connection requirement for a 2-hour (120-minute) layover.
How to use this tool
- Enter your layover duration in minutes (found on your itinerary).
- Enter the minimum connection time for your airport and route type.
- The calculator shows the layover in hours and minutes and how much buffer you have above the minimum.
A 2-hour layover with a 45-minute minimum gives you 75 minutes of leeway — comfortable for most connections.
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.
