The one question that matters on any connection is simple: will you next see your suitcase only at the final airport — or do you have to step out, pull it off the belt and re-check it? The answer drives how much layover time to leave and what to ask at the check-in desk.
On a single ticket your bag is usually checked straight through to the final stop — no need to collect it at the connection. On separate tickets, when changing airline or alliance, or when entering a country with customs, you often have to claim and re-check it. The exact rules depend on your route and airports, so always confirm what happens to your bag at check-in and review your itinerary in My bookings.
01 / What it isWhat through-checked baggage means
Through-checking means you drop your suitcase once at the first airport and pick it up only at the final destination. During the layover the bag is transferred between flights by airport staff — you don't visit the baggage belt. In that case your bag tag usually shows the final destination airport code, not the transfer point.
02 / Goes throughWhen the bag travels through on its own
Through-checking most often works on a single ticket — when all segments sit in one booking and the flights are operated by one airline or by alliance partners. The bag then usually goes to the final stop by default, and the layover is just a walk to your next gate.
- Single ticket for the whole route — one booking reference across all segments.
- One airline, or alliance partners with a baggage-transfer agreement.
- Transit zone: you stay airside and don't clear the connecting country's customs.
03 / Collect yourselfWhen you must collect the bag at the connection
In some cases the bag is not tagged all the way through, so you have to claim it on the belt and re-check it for the next flight. The main triggers are separate tickets and crossing a border with a customs check. In these cases, leave noticeably more layover time.
04 / Step by stepWhat to do before your connection
Check your ticket in advance
Open My bookings and see whether it's a single ticket or several. One booking reference across all segments is a good sign.
Ask at check-in
Ask the agent which airport the bag is checked to, and read the city on the tag — is it the final stop or the transfer point?
Leave enough layover time
If you have to collect the bag, account for the belt, customs, re-screening and re-check. A short layover won't be enough.
Keep tags and boarding passes
Keep the tag stubs and both boarding passes — they help if the bag goes missing or the route changes.
05 / FAQFrequently asked questions
How do I know if my bag goes straight through?
The most reliable way is to ask at check-in which airport the tag is issued to. If it's your final destination, you don't collect the bag at the connection. A single ticket with one booking reference across all segments is a good indirect sign.
I have two separate tickets. Will I definitely have to collect the bag?
Most likely yes: with separate bookings you usually need to claim the bag and re-check it for the next flight. The airlines generally won't transfer it between them, so leave several hours for the connection with a buffer.
Do I collect the bag if I enter a country at the connection?
Often yes. If you clear customs and enter the country at the transfer airport, you usually have to claim and present the bag, then re-check it for the next flight. Confirm the exact procedure at the desk — rules vary by country and airport.
How much time should I leave for a connection?
If the bag goes through, you only need the walk between gates with a buffer. If you have to claim and re-check it, allow noticeably more time for the belt, control and check-in. See the connection-time article for specific minimums.
