MCT is the shortest scheduled interval accepted for a defined transfer, not a guarantee that every passenger will comfortably make it.

MCT is a rule for building itineraries

Reservation systems compare scheduled arrival and departure with the applicable minimum. The value can vary by terminal, carrier, flight type and exception; there is no single universal number for an airport.

Valid does not mean generous

The threshold makes a connection saleable under defined conditions. Walking speed, queues, mobility needs, security, immigration and gate closure can require more time.

One ticket changes the recovery path

When protected segments are issued together, the airline normally has a process if disruption breaks the connection. Separate tickets may leave the traveller responsible for rebooking, baggage and new check-in.

IATA

A valid ticket and a comfortable transfer are different

A published minimum connection time permits a supported itinerary to be sold under specified conditions. It cannot predict a late inbound aircraft, a long walk, security re-screening or a baggage exception. Compare the actual terminal change and the next available service, especially on the last flight of the day. Separate tickets can leave the traveller responsible for a missed onward flight even when each individual flight is on time.

Work backwards from the boarding deadline

Consider a fictional 75-minute scheduled connection. If the onward gate closes 20 minutes before departure, the usable interval ends before the printed departure time. Deplaning, walking, security or border control still consume that interval. Do not subtract only the walking time, and do not interpret this illustration as a valid minimum at a real airport: itinerary-specific rules and delays remain decisive.

Questions about this topic

Is a connection just above the minimum comfortable?

Not necessarily. The minimum validates a specified transfer, not your walking speed or queue length. Check terminals, security, passport control and boarding deadlines; separate tickets can require baggage reclaim and a new check-in.

What should I add to a personal transfer assessment?

Terminal route, documents, luggage handling, mobility needs and the consequence of missing the next flight. A valid booking is not a guarantee of an effortless transfer.
