What happens if you miss your connecting flight, what happens if you miss a connecting flight booked separately, and what the rule says if my flight is delayed and i miss my connection

The missed connection is the disruption where the paperwork decides the outcome, and where two passengers walking off the same delayed aircraft can be owed completely different things. What matters is not how late the first flight was but whether the whole journey was sold as one contract. Everything else, including whether any compensation is due at all, follows from that single fact and from how late you eventually reached your final destination.

One booking: the delay is measured at the end, not in the middle

Where the journey is a single reservation, the retained UK Regulation measures a delay by when you reach your final destination, and the compensation right is expressed in exactly those terms: a delay of three hours or more in reaching the final destination carries the right to compensation. A ninety-minute inbound delay that costs you a connection and lands you five hours late is therefore a five-hour delay for these purposes, not a ninety-minute one. The distance used for the band is the whole journey to that last destination, which is why a short first leg can carry a long-haul figure.

Two bookings: the second airline owes you nothing

If you bought the legs separately, there is no single contract of carriage, and the airline operating the second flight has simply seen a passenger fail to arrive. It owes no re-routing, no care and no compensation, and it is entitled to treat the ticket as a no-show. The first airline's liability, if any, ends with its own flight. This is the trap in self-connecting itineraries, and it is worth checking before booking rather than after: a single reservation covering both legs is what buys the protection, not being in the same terminal.

What the airline owes you while you wait for the next seat

On a single booking, an inbound delay long enough to cost a connection normally also triggers the assistance obligations: the choice between a refund and re-routing to the final destination at the earliest opportunity, and the right to care while you wait. Care means meals and refreshments in reasonable relation to the waiting time and a hotel where an overnight stay becomes necessary, and it applies whatever the cause. Ask for it at the transfer desk rather than buying your own and hoping, and keep every receipt if the desk refuses.

Missing it through your own fault is a different question

None of this reaches the passenger who was late to the gate. A missed connection caused by a queue at security, a long walk between terminals on a legal but tight transfer, or simply not hearing the call is a no-show, and what happens next is governed by the airline's fare rules rather than by any of these instruments. The distinction the regulations care about is whether the carrier caused the miss. That is also why the first thing to establish is the inbound flight's actual arrival time, which is a matter of record.

Questions people ask about what happens if you miss your connecting flight

If my flight is delayed and i miss my connection, how is compensation measured?

On a single booking, by how late you reach your final destination rather than by the length of the first delay. Reaching the last airport three hours or more late is what carries the right under the retained UK Regulation.

What happens if you miss a connecting flight you booked separately?

The second airline treats you as a no-show and owes nothing, because there is no single contract of carriage covering both legs. The first airline's obligations end with its own flight.

Does the airline have to put me on the next flight?

On a single booking the Regulation gives you the choice between reimbursement and re-routing to your final destination at the earliest opportunity under comparable transport conditions. Which of the two you want is your choice, not the airline's.

Does this work the same way in the United States?

The mechanics of rebooking do, because a single ticket is a single contract there too, but the money does not: the US rules give a refund where you decline what is offered and no payment for arriving late. There is no US equivalent of the three-hour rule.
