A self-transfer is when you book two separate tickets and connect yourself — collecting and re-checking bags, and re-clearing security. It's often cheaper, but if the first flight is late, no airline will rebook you. Allow at least three hours and consider insurance.
Booking sites increasingly sell ‘self-transfer’ or ‘virtual interlining’ itineraries that stitch together flights on airlines with no agreement between them. They look like one trip but are legally two.
What that means:
- Your bags are not checked through — you collect them, clear customs, and re-check at the second airline’s desk.
- You clear security again.
- If the first flight is delayed or cancelled and you miss the second, the second airline treats you as a no-show. You buy a new ticket.
How to do it safely:
- Allow three hours minimum, more if you change airports or the destination needs immigration.
- Check whether the booking platform offers a ‘connection guarantee’ (some do, for a fee).
- Buy travel insurance that covers missed connections.
- Only carry-on if you can, to skip the bag re-check.
A true connection on one ticket is always safer; the savings on a self-transfer come with real risk.

Is a 1-hour layover enough to make my connection?
For a same-terminal domestic connection on one ticket, usually yes. For international connections, terminal changes, or if you need to clear immigration or re-check bags, one hour is risky. Never attempt a 1-hour connection on separate tickets. Full answer →
What happens if I miss my connecting flight?
On a single ticket, the airline rebooks you on the next available flight at no charge, and may owe meals or a hotel if the delay was its fault. On separate tickets you're on your own — you'll buy a new ticket. Full answer →
How do I find cheap flights?
Search flexible dates on Google Flights and Skyscanner, check nearby airports, set price alerts, consider one-stop routings and stopover programs, and compare the total cost with bags and seats — not the headline fare. Full answer →
