How we make money .* # Missed Connections & Codeshare Flights: UK261 Rules Explained (2026) UK261 treats connecting flights on one booking (single PNR) as a single journey — compensation is based on arrival delay at the final destination, even if only the first leg was late. Separate tickets are independent: missing a connection on ticket two because ticket one was delayed creates no UK261 claim against the second airline.

If you booked Manchester–Heathrow–Bangkok on one ticket and the Manchester–Heathrow leg arrived late enough to cause a 4+ hour delay reaching Bangkok, the carrier responsible for the delay owes compensation based on Manchester–Bangkok distance — even if the long-haul sector departed on schedule after you were rebooked. When all flights share one booking reference (PNR), UK261 treats the itinerary as one trip to a final destination. If you booked Manchester–Heathrow–Bangkok on one ticket and the Manchester–Heathrow leg arrived late enough to cause a 4+ hour delay reaching Bangkok, the carrier responsible for the delay owes compensation based on Manchester–Bangkok distance — even if the long-haul sector departed on schedule after you were rebooked. The responsible carrier is usually the one operating the flight that caused the knock-on — but airlines dispute this. File with the operating airline of the delayed segment first; if bounced, include all carriers on the booking and let ADR assign liability. Minimum connection times (MCT) matter for airline liability internally but not for your entitlement — if the airline sold you a 45-minute connection at Heathrow and you missed it, that is their scheduling problem on a single ticket. ## Separate tickets — no connection protection Budget-travel "self-transfer" itineraries — flying easyJet to Amsterdam then separately booking KLM to Nairobi on a different ticket — are two unrelated contracts. If the easyJet leg is delayed and you miss the KLM flight, KLM owes nothing under UK261 unless its own flight was also delayed 3+ hours. easyJet owes compensation only for the AMS arrival delay on the first ticket, not for the missed long-haul.

Travel insurance with "missed departure" or "missed connection" cover is the primary remedy for separate tickets. Policies vary: some require 3+ hour delay on the inbound flight; others exclude self-transfers entirely. Read the wording before relying on it. Build buffer time: 3+ hours for same-terminal connections, 4+ hours for cross-terminal at multi-terminal hubs (Heathrow, JFK), and overnight buffers for long-haul self-transfers. The savings on split tickets rarely justify a missed intercontinental flight. ## Codeshare and wet-lease — who pays? UK261 liability sits with the operating carrier — the airline whose flight number is operated on its own aircraft and crew. A ticket sold as "British Airways" but operated by American Airlines from New York to London is an American operation; UK261 does not apply to inbound US carriers that are neither UK nor EU.

A ticket sold as "British Airways" but operated by American Airlines from New York to London is an American operation; UK261 does not apply to inbound US carriers that are neither UK nor EU. Outbound from the UK, any departing flight is covered regardless of operator nationality — so an Emirates Manchester–Dubai delay triggers UK261 against Emirates even if you booked through a travel agent. Wet-lease situations (one airline providing aircraft and crew to another) still point to the operating carrier on the day of flight — check the airport departure board and boarding pass for the actual operator code if compensation is rejected on "wrong airline" grounds. ## Package holidays and tour operator flights Flights within ATOL-protected package holidays are still covered by UK261 for delay compensation — claim against the operating airline, not the tour operator. Package Travel Regulations may additionally give refund rights if the holiday changes fundamentally, but that is separate from per-passenger UK261 cash.

Package Travel Regulations may additionally give refund rights if the holiday changes fundamentally, but that is separate from per-passenger UK261 cash. If the tour operator rebooks you onto a much later flight, measure UK261 delay against your original scheduled arrival at destination — not the rebooked flight if you were forced to accept it without voluntary waiver of rights. ## Practical checklist before booking connections Prefer single-ticket connections sold by one airline or alliance partner — UK261 protection and airline rebooking duty apply throughout. Avoid separate tickets for intercontinental connections unless you accept insurance-only protection and long buffer times.

Avoid separate tickets for intercontinental connections unless you accept insurance-only protection and long buffer times. Screenshot MCT and connection times at booking. If an OTA sells an impossibly tight self-transfer, the OTA is not liable for UK261 — but you may have consumer rights against the agent under UK consumer law for misleading sales in some cases. On delay day, do not voluntarily accept voucher-heavy rebooking packages without checking whether you are waiving UK261 compensation — read the small print before signing at the airport desk.

Yes if all flights were on one booking and you arrived 3+ hours late at final destination due to airline fault. No if you held separate tickets — only the delayed flight's segment may qualify independently. ### Do I claim against the first airline or the connecting airline? Usually the operating carrier that caused the initial delay on a single booking. File with that airline first; ADR can allocate if carriers dispute. ### Does UK261 apply to codeshare flights? Yes when coverage rules are met — but always against the operating carrier. Marketing airline name on the ticket does not change liability. ### Are self-transfer flights worth the savings? Only with long buffers and missed-connection insurance. UK261 will not link separate tickets — a £80 fare saving can cost a £600+ long-haul ticket if the first leg slips. ### Package holiday flight delayed — who do I claim from? The operating airline under UK261. ATOL protects against operator insolvency; UK261 pays fixed delay compensation per passenger when fault and delay thresholds are met.
