General planning estimate only. Check the airline/airport’s official minimum connection time, baggage transfer, transit visa and missed-connection rules.
What this tool does
Calculate the time between an arriving flight and the next departure, then compare it with a simple planning buffer for domestic or international connections, terminal changes, immigration and baggage re-checks.
Minimum connection times vary by airport, airline, ticket type and itinerary. This calculator is a planning aid only. It does not know your airport’s official minimum connection time, live delays, gate location or airline protection rules.
Useful for
- Calculate the scheduled time between two flights.
- Estimate whether a connection looks comfortable or tight.
- Account for international transfers, terminal changes and baggage re-checks.
- Compare multiple itinerary options before booking.
How to use it
- Enter the scheduled arrival and next departure date/time.
- Choose domestic or international transfer.
- Select extra transfer factors that apply.
- Calculate the layover and compare it with the planning buffer.
Worked examples
Domestic same-terminal connection
InputArrival 10:00, departure 12:00
Result120-minute layover compared with a basic domestic planning buffer.
Official airport/airline rules still take priority.
International terminal change
InputArrival 14:00, departure 17:30, immigration + terminal change
Result210-minute layover with a larger suggested planning buffer.
Baggage and visa/transit rules should be checked separately.
Common mistakes to avoid
- Comparing times without including the correct date.
- Assuming all airports use the same minimum connection time.
- Ignoring immigration, security or baggage re-check requirements.
- Booking separate tickets without considering missed-connection protection.
Before you use the result
- Check the airline’s official connection guidance.
- Confirm whether bags are checked through to the final destination.
- Review transit-visa and immigration requirements.
- Check terminal maps and current airport guidance.
Edge cases and limitations
- Overnight connections may cross midnight.
- Separate tickets can require collecting and re-checking baggage.
- Airport construction or terminal transfers can increase connection time.
- Weather and operational delays are not included.
Practical tips
- Choose a larger buffer when traveling with children or reduced mobility.
- Allow extra time for unfamiliar or very large airports.
- Avoid relying on the calculator as a guarantee that a connection is valid.
- Check whether the airline sells the itinerary on one protected ticket.
