Missed your connection: what you are owed

If a delay made you miss your connection, one fact decides almost everything: were both flights on a single booking, or did you buy separate tickets?

On a single booking you are usually well protected. On separate tickets you are, in most cases, on your own.

Single booking: the journey counts as a whole

When both legs are on one reservation, EC 261 treats the trip as a single journey. The delay that matters is your lateness at the final destination, not the length of the first leg's delay.

A forty-minute delay leaving Berlin that causes you to miss a Frankfurt connection and arrive in Chicago seven hours late produces a claim based on seven hours — and on the full Berlin–Chicago distance, so the €600 tier.

The Court of Justice confirmed this in Wegener (C-537/17): a connecting itinerary booked as one contract is assessed as a whole, even where the connection point lies outside the EU. Note that in that case the journey departed from the EU.

It also held in České aerolinie (C-502/18) that where an EU carrier operated your first leg on a single booking, it remains liable for a delay on a later leg flown by a non-EU partner. You claim from that carrier; the codeshare arrangement is their problem, not yours.

The trap: a stopover in the EU is not enough

This catches a lot of people, and it is worth being precise about.

If your journey starts outside the EU and ends outside the EU, EC 261 does not apply — even on a single booking, even on an EU airline, and even if you change planes at an EU airport. The Court settled this in Airhelp v Austrian Airlines (C-451/20), a Chișinău–Vienna–Bangkok itinerary on an EU carrier: no compensation under EC 261.

So an Istanbul–Frankfurt–Chicago trip is outside EC 261 despite the Frankfurt stop. What covers it instead is SHY-YOLCU, because the journey departs from a Turkish airport, and its compensation scale matches EC 261's. Claim under the right regulation and you get paid; claim under the wrong one and you get a refusal letter that looks like a rejection on the merits.

Separate tickets: the chain breaks

Two independent bookings are two independent contracts. The first airline owes you for its own delay, which on its own is often under three hours and produces nothing. The second airline owes you nothing at all — from its point of view you simply failed to show up, and your fare is usually forfeited.

You also have to collect and recheck your baggage yourself, which is where the connection time you thought you had disappears.

Some booking platforms sell "self-transfer" itineraries with their own guarantee. That guarantee is a commercial promise from the platform, not a passenger right, and its value depends entirely on the platform's solvency and goodwill. Read what it actually covers before relying on it.

What the airline owes you on a single booking

Rerouting. The airline must get you to your destination at the earliest opportunity, buying you a seat on another carrier if that is what's soonest. You should not have to pay for the replacement.

Care while you wait. Meals, communications, and a hotel with transfers if the wait runs overnight. This applies regardless of the cause — bad weather included.

Compensation, if you arrive three or more hours late and the cause wasn't extraordinary. Amounts and the extraordinary circumstances test are covered on the flight delay compensation page.

Minimum connection time is not a promise

Every airport publishes a minimum connection time, and booking systems won't sell you anything below it. That figure is an operational minimum, not a guarantee — it assumes an on-time arrival, no gate change and no terminal transfer at walking pace.

If your itinerary is at or near the minimum, a small delay puts you out. Where the schedule matters, the extra hour is worth more than the fare difference.

Practical steps at the airport

1. Go to the transfer desk rather than leaving airside. Rebooking is faster and simpler before you clear immigration.
2. Ask for the rebooking in writing and note the new flight details.
3. If you're told to buy your own replacement ticket, ask for that instruction in writing, then buy a reasonable fare and claim it back. Do not buy a premium cabin and expect reimbursement.
4. Keep receipts for meals and hotels if the airline provides nothing.
5. Note your actual arrival time at the final destination — the moment the door opened. That number drives the compensation claim.
