Codeshare Flight Delayed? How to Claim Your Compensation

With a codeshare flight, you book with one airline, but a different one operates the flight. If that flight is delayed or cancelled, you are entitled to EUR250-600 compensation under EU Regulation 261/2004. Important: your complaint must always go to the operating carrier, not the airline you booked with. This was established by the ECJ in the Wegener ruling (C-532/17).

Marketing Carrier vs. Operating Carrier

The airline you purchased the ticket from
Their flight number appears on your ticket

Operating Carrier (Operating Airline)

The airline whose aircraft and crew operate the flight
Identifiable by 'operated by' note or on your boarding pass
RESPONSIBLE for EU261 compensation (ECJ C-532/17)

Frequently Asked Questions

What is a codeshare flight?

In a codeshare flight, Airline A sells a ticket under its own flight number, but the flight is actually operated by Airline B. Your ticket will show something like 'LH 1234, operated by Eurowings'. This is common practice, especially within airline alliances like Star Alliance, oneworld, or SkyTeam.

Who do I contact for a codeshare flight complaint?

Always the operating carrier — the airline whose aircraft and crew actually operated the flight. This was clarified by the ECJ in case C-532/17 (Wegener). If you booked with Lufthansa but Eurowings operated the flight, you must contact Eurowings.

Which flight number applies for my complaint?

For your EU261 complaint, the operating carrier's flight number is the relevant one, not the booking airline's number. You can find it on your boarding pass, in your booking confirmation (often marked as 'operated by'), or on flight tracking websites like Flightradar24.

Can I contact the booking airline instead?

Legally, only the operating carrier is obligated to pay EU261 compensation. In practice, some booking airlines may forward your complaint, but this is not guaranteed and may delay the process. Contact the operating carrier directly.

What about codeshare with connecting flights?

If a connecting journey on a single booking involves different airlines operating different legs: for a delay at the final destination, you must contact the airline that actually operated the delayed leg (the segment that caused the delay). Compensation is based on the total distance from origin to final destination.

Does EU261 apply to codeshare flights with non-EU airlines?

EU261 applies if the flight departs from the EU (regardless of airline) or if it arrives in the EU and is operated by an EU airline. For codeshare flights, the operating carrier matters: if the flight departs from the EU, the operating carrier is responsible regardless of where it is based. If the flight arrives in the EU, the operating carrier must be EU-based.

How do I find out who the operating carrier is?

Check your boarding pass — it always shows the operating airline. Alternatively, find the information in your booking confirmation ('operated by' notice), on the booking airline's website under your booking details, or on flight tracking websites.
