How Connecting Flights Work (and When to Risk a Self-Transfer)
A connecting flight on a single ticket is the airline’s responsibility: if you miss the connection because the first flight was late, they rebook you. A self-transfer — two separate tickets — is two separate contracts: if the first is late, the second airline owes you nothing.
How Connecting Flights Work (and When to Risk a Self-Transfer): questions people actually ask
Will my baggage transfer automatically on a connection?
On a single ticket, normally yes, checked through to your destination. On self-transfers, no — you collect and re-check.
What happens if I miss a connecting flight?
On one ticket the airline rebooks you, usually on the next available service. On separate tickets you buy a new ticket at walk-up fares.
How much time should a self-transfer allow?
Three hours minimum without checked bags; more with bags, or when immigration is involved.
Single-ticket connections
Booked as one itinerary (even across partner airlines), a connection protects you: checked bags move through, missed-connection rebooking is the airline’s problem, and delay compensation rules may apply. Airports publish minimum connection times — 45–60 minutes short-haul, 60–120 international — and bookable itineraries respect them.
Self-transfers: cheap but rigid
Two separately-booked flights can be dramatically cheaper, sometimes because one leg is a low-cost carrier the big metasearch engines deprioritise. The trade: leave generous buffer (three-plus hours on separate tickets, more if bags are checked), and remember you may need to clear immigration and re-check bags.
How to tell which you are buying
One booking reference for both legs = protected connection. Two references = self-transfer. If a results page shows a “self-transfer” or “separate tickets” label, that is exactly this distinction — treat it as a different product, not just a cheaper one.
