## The Short Answer: Yes, Connections Qualify — But the Rules Around Them Are Strict

A connecting flight booked under a single reservation absolutely qualifies for EC 261/2004 compensation, provided the disruption forces you to arrive at your final destination three hours or more late. The critical detail most passengers misunderstand is where the three-hour clock starts and stops. Under the regulation, delay is measured at the final destination printed on your booking, not at any intermediate connection point. So a two-hour-late first leg that causes you to miss a connection and arrive five hours late at your ultimate destination clearly triggers compensation eligibility, even though no single flight segment was delayed by more than three hours.

The second critical detail is what "single reservation" actually means. If your entire itinerary was issued under one booking reference (one PNR), on the same carrier or on partner airlines operating under a codeshare agreement, and the connection was originally scheduled tight enough that a delay on the inbound leg could not reasonably be recovered, the operating airline is liable for compensation on the full fare-paid distance to your final destination. If, however, you booked two completely separate tickets — say, a Ryanair flight from London to Madrid on one confirmation code and an Iberia flight from Madrid to Lisbon on another — the second airline has no contractual or regulatory obligation to protect you, and you typically have no claim even when the first airline's delay caused the problem.

This single-versus-separate distinction is the single most litigated point in EU261 claims and the place where passengers lose the most money.

## Why the Single-Booking Rule Exists

The European Court of Justice and national courts have consistently interpreted EC 261/2004 to protect passengers whose journeys are sold as a single commercial product. When you buy a connection through a single booking, the airline is treating your trip as one contract of carriage, even if it involves multiple aircraft and multiple flight numbers. The operating carrier is responsible for getting you from the origin printed on the ticket to the final destination printed on the ticket.

This interpretation was tested in cases such as the Siewert and Müller line of decisions, where the Court of Justice of the European Union confirmed that for connecting flights operated under a single reservation, the operating air carrier of the first leg bears responsibility for the entire journey if it fails to get the passenger to the final destination on time. The Court reasoned that the passenger purchased a single ticket for a single journey; the airline cannot escape liability by fragmenting the contract into legs.

Codeshare flights fall under the same principle, but with an additional layer. When you book an American Airlines-marketed flight operated by British Airways, the marketing carrier (the one whose code is on the ticket) is the contract carrier, while the operating carrier is the one whose crew and aircraft actually fly the segment. Under EC 261/2004, the operating air carrier of the flight that caused the delay is the one that pays compensation, not necessarily the carrier whose name is on the ticket. This can create practical complications when filing claims, because the operating carrier's customer service may try to deflect you to the marketing carrier, and vice versa.

## What Counts as a "Connection" Under the Regulation

The regulation does not actually use the word "connection" — it uses the concept of "connecting flights" in Article 2(h) and recitals that discuss direct flights versus multi-segment journeys. For the three-hour threshold to be measured at the final destination, the journey must be a single ticket purchase and the segments must be part of the same operating itinerary. A stopover that is part of the routing — for example, London to Frankfurt to Athens with a planned 90-minute layover — qualifies. A stop you added later by booking a second ticket does not.

Distance matters enormously for the compensation amount, which is why the table below is worth studying before you file any claim.

## Compensation Amounts by Distance and Delay Length

| Route distance (final destination from origin) | Delay at final destination | Compensation per passenger |
| --- | --- | --- |
| Up to 1,500 km | 2 hours or more | €250 |
| 1,500–3,500 km (intra-EU) | 3 hours or more | €400 |
| 1,500–3,500 km (non-EU origin/destination) | 3 hours or more | €400 |
| Over 3,500 km | 3 hours or more | €600 |
| Over 3,500 km (extraordinary circumstances) | 4 hours or more | €600 |

For connecting flights, distance is measured in a straight line (great-circle distance) between the origin airport of the first segment and the destination airport of the last segment, using the full itinerary on the single ticket. This can work in your favor — a London–Frankfurt–Athens connection might qualify for the €250 short-haul tier, while a London–Dubai–Sydney connection on a single booking could qualify for the full €600.
Children under two sitting on a parent's lap receive no compensation. Children in their own seat are entitled to the full amount, same as adults. Downstream connecting flights with a delay of less than two hours at the final destination qualify for nothing.

## The Separate-Ticket Trap and Why It Costs Passengers Dearly

The single most expensive misunderstanding in EU261 claims is the belief that any delay caused by an airline triggers compensation on a downstream flight. It does not. The regulation's liability runs with the contract of carriage. If you book two independent tickets, you have two independent contracts, and the airline on the second contract has no obligation to reroute you, rebook you, or compensate you for the first airline's delay.

A practical example: you book a KLM flight from Amsterdam to Paris on ticket number 074-1234567, arriving at 10:00, and separately book an Air France flight from Paris to Lisbon on ticket number 057-9876543, departing at 11:30. KLM arrives at 11:45 due to a technical issue. You miss the Air France flight. Air France cancels your return or rebooks you on the next day's flight. You have no EU261 claim against Air France, because they fulfilled their contract — they operated the flight you paid them to operate. You have a possible claim against KLM for delay on the Amsterdam–Paris leg, but the compensation will be the €250 short-haul tier because that is the distance of the first ticket, not the entire itinerary.

This trap is so common that airlines have begun selling "protected connections" — meaning they will rebook you on a later flight at no extra cost even on separate tickets — as a paid add-on at checkout. Budget carriers in particular, including Ryanair and Wizz Air, actively disclaim liability for missed connections on other airlines regardless of how the delay was caused.

## Extraordinary Circumstances: When the Airline Still Pays

Even when the single-booking test is met, airlines can refuse compensation if the delay or cancellation was caused by extraordinary circumstances beyond their control. EC 261/2004 Article 5 lists examples including political instability, weather incompatible with safe operation, security risks, strikes (with caveats), and unexpected flight safety shortcomings discovered during pre-flight checks.

The 2024 amendments to the regulation, which took effect for flights departing on or after June 1, 2025, refined the extraordinary-circumstances definition and clarified that staffing shortages, technical problems, and wildcat strikes by an airline's own employees generally do not qualify as extraordinary. A technical fault that prevents an aircraft from departing is treated as an inherent part of normal airline operations, not an unforeseeable external event. A pilot strike by the operating carrier's own staff is similarly treated as the airline's responsibility.

This change has produced a meaningful shift in compensation eligibility. Pre-2025, technical delays were heavily contested. Post-2025, airlines must prove the technical issue was caused by a third party or by sabotage, which is a much higher bar. Wildcat strikes, where employees walk off the job without union authorization, also fall under the airline's operational risk, not the extraordinary-circumbstance exemption.

## Practical Steps to File and Win a Connecting-Flight Claim

The first step is to determine whether your journey was on a single booking. Open the email or booking confirmation from the original purchase. If you see one PNR, one e-ticket number, or one booking reference covering all segments, you have a single reservation. If you see two separate confirmation numbers, you have two separate contracts regardless of how the airline marketed the trip to you.

The second step is to calculate the arrival time at the final destination. EC 261 measures delay at the moment the aircraft door opens at the gate of the final airport, not at the moment the wheels touch down. If the doors open at 18:45 and the scheduled arrival was 14:00, you have a four-hour, forty-five-minute delay, which exceeds the three-hour threshold for any distance category.

The third step is to gather evidence. Save your boarding passes, your booking confirmation, any emails or SMS messages about the delay, screenshots of the airline's app showing the revised arrival time, and receipts for any meals, hotels, or transportation you purchased because of the delay. These expense receipts are not the same as EU261 compensation — they are reimbursement claims under Article 9 of the regulation, which is a separate entitlement for care and assistance.

The fourth step is to file the claim directly with the operating carrier of the disrupted flight segment, using the airline's official EU261 claims form or a written demand that cites the regulation by article number. Airlines are required to respond within six weeks, though many take longer. If the airline refuses or ignores you, the next step is the national enforcement body of the departure country's aviation authority, and finally the courts.

## Common Mistakes That Kill Valid Claims

The first mistake is waiting too long. Most EU member states enforce a statute of limitations of one to three years, with Germany at three years, France at five years for delayed baggage but shorter for compensation, and the UK at six years under the post-Brexit UK261 regime. The longer you wait, the harder it is to retrieve booking records from the airline.

The second mistake is accepting vouchers. If the airline offers you a €50 voucher as "compensation" for a four-hour delay on a €600-eligible long-haul connection, that is not a settlement — it is a lowball. You are entitled to €600 in cash or bank transfer, not in credits that may expire before you use them.

The third mistake is claiming the wrong amount. Passengers frequently claim €600 on short-haul connections when the actual distance qualifies them for €250, and then the airline's automated system rejects the claim because the amount exceeds what is legally owed. Always calculate the great-circle distance using a free online tool before submitting.

The fourth mistake is ignoring codeshare. If your ticket says "LH 901 operated by UA" — Lufthansa flight 901 operated by United Airlines — the operating carrier for compensation purposes is United, not Lufthansa. File with United. If you file with Lufthansa, they will likely reject the claim because they did not operate the aircraft.

The fifth mistake is failing to keep evidence of the connection itself. A claim that says "my flight was late" without specifying which leg caused the disruption and how that propagated to the final destination is weaker than a claim that says "Flight XX123 arrived at 15:20 instead of 14:00, causing me to miss Flight YY456 departing at 15:30, resulting in arrival at the final destination at 21:00 instead of 17:30, a four-hour delay."

## When You Should and Should Not Pursue a Claim

You should pursue a claim whenever the final destination delay exceeds the relevant threshold, the journey was on a single booking, and the disruption was not caused by extraordinary circumstances. For amounts up to €250, many third-party claim services will pursue the claim for a 25% to 30% commission, which may be worth the convenience if you do not want to write a formal letter in a foreign language.

You should also pursue the claim yourself if the amount is large (€400 or €600), because a third-party service that charges 30% takes €120 to €180 off your compensation, and the airline's customer service is typically responsive to a well-written, regulation-citing letter sent via email. Several national enforcement bodies — including Germany's LBA, Spain's AESA, and France's DGAC — provide model claim letters in multiple languages that you can adapt.

You should not pursue a claim if the delay was caused by weather at your origin or destination, by an airport closure unrelated to the airline, or by a security incident. You also should not pursue a claim on a separate ticket, because doing so wastes time and may weaken your credibility with the airline for future legitimate claims.

If the disruption is part of a mass event — a strike, a volcanic ash cloud, a regional conflict — airlines will deny claims en masse. In those cases, the national enforcement body often takes the lead and may publish a list of denied claims that are eligible for collective action. Holding off for a few weeks after a major disruption is sometimes the smarter move, because the legal landscape may shift in response to regulatory guidance.

The bottom line is straightforward: a connecting flight qualifies for EC 261/2004 compensation when the journey is on one ticket, the final destination is delayed by the regulatory threshold, and the cause was within the airline's control. Understanding the single-ticket test is the difference between a €600 payout and walking away with nothing.

## Quick answers

### Does a connecting flight qualify for compensation?

Yes, if the entire journey was booked under a single reservation (single PNR or booking reference) on the same or codeshare airlines.

### Where is the 3-hour delay measured?

The delay is measured at the final destination of the entire booking, not at the connection point.

### Do separately booked tickets qualify?

Separate tickets bought independently generally do not qualify, even if the missed link was caused by the first airline's delay.
