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.

What can you actually do during a layover?
An honest rule of thumb, based on the gap between flights:
- Under 1 hour — assume you will only just make the connection. Stay near the gate.
- 1–2 hours — enough for a proper meal, a lounge, or a stretch of the terminal. Stay airside.
- 3–5 hours — time to relax, shower in a lounge, or explore a big airport’s shops and food.
- 6+ hours (international) — you may be able to leave the airport and see the city, but only if you can legally enter the country (you hold any required visa or transit visa for your passport) and you leave a big enough buffer to clear immigration out, travel, and re-clear security and passport control on the way back — budget 3–4 hours of airport overhead on top of travel time.
Always check your own passport and route. Transit-visa rules depend on your nationality and on whether you switch terminals or airlines. When in doubt, stay airside.
