There are two very different versions of a missed connection. If everything is on one ticket, the airline owns the problem and has to move you. If you bought two separate tickets, the second airline technically owes you nothing, and you are in a negotiation.
Know which version you are in before you speak to anyone, because it changes what you should ask for.
One ticket or two
A single ticket means one booking reference covering the whole journey, even when different airlines operate the legs. You should be rebooked at no extra cost, and your checked bag continues automatically.
Two separate tickets mean two contracts. The second airline may charge a change fee or a new fare. Some carriers are flexible if you reach them early and explain, so getting to a desk quickly is worth more than arguing about fairness.
Step by step
Step 1: Start rebooking before you land, if you can
If onboard wifi is available, or you have a few minutes of signal after landing, open the app and look for a self service rebooking option. Many airlines automatically place you on the next flight and send the new boarding pass, which saves the queue entirely.
Step 2: Go to the transfer desk, not the check in hall
In most airports the connections or transfer desk sits inside the secure area, right after arrivals from your gate. Do not clear immigration or exit unless you are told to. Leaving the transit zone can mean visas, re screening and a much longer walk back.
Step 3: Ask precise questions
Ask for the next available seat to your final destination, then ask what else is possible: another airline, another nearby airport, an evening departure through a different hub. Agents work with what you ask for. A specific request often produces a better option than a general complaint.
Step 4: Sort baggage and the night
On one ticket your bag is normally retagged automatically, but confirm it and get the new tag number. If the next flight is tomorrow, ask about a hotel and transport, and ask for an overnight bag if your things are checked through.
If the airline refuses to help
- Buy the cheapest reasonable onward option yourself and keep every receipt for a later claim.
- Separate tickets are sometimes covered by travel insurance under missed departure clauses.
- Check trains and buses for short hops, they can beat waiting for tomorrow morning.
- Write down the name of the agent you spoke with and the time.
