Connecting Flight

A flight itinerary requiring a passenger to change aircraft at one or more intermediate airports before reaching the final destination.

A connecting flight is a journey that involves at least one transfer at an intermediate airport, where the traveler disembarks from one aircraft and boards another to continue to their final destination. Unlike a direct flight, which travels between two airports without changes, a connecting flight may involve layovers of varying lengths. The time between flights is referred to as the connection time, and carriers publish minimum connection times (MCT) to indicate the shortest permissible gap for making a transfer. Connections can be same-airline or involve multiple carriers under interline or codeshare arrangements.

Why it matters

Connecting flights introduce risk that non-stop or direct flights do not: missed connections due to delays, misrouted baggage, and longer total journey times. For corporate travellers on tight schedules, the choice between a connecting itinerary at a lower fare and a non-stop at a premium is a genuine trade-off that travel policy should address. Programme managers who set minimum connection time standards help travellers avoid itineraries with inadequate buffer and the cost consequences of missed connections.

How it works in practice

When a traveler books a connecting itinerary on a single ticket, the airline is responsible for rebooking if the inbound flight causes a missed connection. Itineraries booked as separate tickets — even on the same carrier — do not carry this protection; the traveler bears the full cost of rebooking if the first leg runs late. Baggage is typically checked through to the final destination on single-ticket connections, though travellers should confirm this at check-in, especially on itineraries involving different airlines.

The takeaway

Single-ticket connecting itineraries offer both liability protection and through-baggage checking that self-connected itineraries do not. When price differences between single-ticket and self-connected options are compared, factor in the downside cost of a missed connection — rebooking fee, overnight accommodation, and lost productivity — to make a fair total-cost comparison.
