What is a self-transfer — changing planes on separate tickets you must reconnect yourself, including bag reclaim, visa risk and why cheap OTA stitches need wide buffers.
What is a self-transfer?
A self-transfer is a journey where you change flights on separate tickets — you reclaim bags if needed, clear immigration when required, and re-check in yourself; no airline owes you a rebooking if the first flight is late.
Also called an unprotected connection or, in some OTA marketing, virtual interlining. The headline fare can undercut a single-ticket alliance path because each airline prices only its segment. The trade-off is risk: a delay on flight one can void a non-refundable flight two. Travel insurance sometimes sells missed-connection add-ons — read exclusions carefully. policy wording for separate tickets.
Budget enough time for bag reclaim, security, border queues and a second airline’s check-in deadline (often 45–60 minutes for short-haul, longer for long-haul). Overnight buffers are rational when the second ticket is expensive. Minimum connection time does not protect you here.

When is a self-transfer a reasonable choice?
When the saving is large, both tickets are changeable or cheap to replace, you travel hand-luggage only, and you leave a buffer measured in hours — not when you are racing for a once-weekly long-haul or travelling with tight visas.
Example: a £90 separate-ticket connection with a five-hour gap and no checked bags can be rational; a £40 saving with a 70-minute gap and a checked suitcase through customs is not. Positioning hops are often self-transfers by design — see positioning flight.
If an OTA shows one “trip” but two ticket numbers, assume self-transfer until proven otherwise. Same-ticket alliance links are protected connections. Survival tips while you wait: airport layover survival.
