How to use it
- Pick the kind of connection: domestic, international (one ticket) or separate tickets.
- Enter the layover as hours and minutes, from landing to the departure of the next flight.
- Switch on what applies: a terminal change, passport control or customs, and collecting bags.
- Add a delay of the first flight if there is one. Read the spare time and the verdict.
How the time is added up
The tool adds fixed amounts, all in minutes:
| Part | Minutes |
|---|---|
| Domestic connection | 45 |
| International connection | 75 |
| Separate tickets | 120 |
| Change of terminal | 30 |
| Passport control or customs | 45 |
| Collecting and re-checking bags | 30 |
| Delay of the first flight | as entered |
Spare time = layover − time needed. At least 30 minutes of spare time is shown as comfortable, 0 to 29 as tight, and below 0 as too short.
Worked example
An international connection with a terminal change and passport control needs 75 + 30 + 45 = 150 minutes. With a 2 h 30 min layover the spare time is 0 minutes, so the verdict is tight. A delay of 20 minutes would make it too short.
Good to know
These amounts are our own planning figures, not official data. Check the minimum connection time on your booking and the airport’s own information, and leave extra margin at large airports with long walks between gates.
