How to use the layover calculator
Worried a connection is too tight? This tool checks whether your layover clears the minimum connection time, factoring in terminal changes, customs and re-checking bags.
How much layover do you need?
- Domestic: 45-60 minutes is usually enough.
- International: allow 2-3 hours, especially if you change terminals or clear immigration.
- Separate tickets: add a big buffer — you'll likely re-check bags and clear security again.
- Big or unfamiliar airports: pad extra time for long walks and transfers.
