Codeshare Flights: Who Owes You Compensation?

Check your compensation →

You booked a flight with Air France but the plane had KLM livery. You purchased through British Airways but Iberia operated the flight. You see two different flight numbers on your itinerary for the same seat on the same aircraft. Welcome to the world of codeshare flights - one of the most confusing aspects of modern air travel, and a major source of compensation claim errors.

When a codeshare flight is delayed, cancelled, or overbooked, passengers frequently do not know who to claim against. They write to the airline they booked with. The airline says it was not their flight. Weeks pass. The claim goes nowhere. The compensation goes uncollected.

This guide explains codeshare flight passenger rights compensation rules, how to identify the responsible airline, and how FlyPayout navigates the complexity for you.

What Is a Codeshare Flight?

A codeshare arrangement is an agreement where two or more airlines sell seats on the same physical flight under different flight numbers. One airline operates the aircraft as the operating carrier, while the other airline sells tickets under its own flight number as the marketing airline.

Codeshare agreements allow airlines to expand their reach and offer more destinations without the need to operate their own aircraft on every route - benefiting both airlines and passengers by simplifying bookings and enabling smoother connections.

Example: You book flight AF1234 through Air France. When you arrive at the gate, the aircraft is a KLM plane. Your boarding pass shows "Operated by KLM." The physical flight is operated by KLM - Air France is the marketing airline selling seats under its own AF flight number.

This codeshare arrangement is extremely common. Major airline alliances (Star Alliance, SkyTeam, Oneworld) and bilateral partner airline relationships use codeshares extensively.

British Airways, Iberia, and Vueling share codes within the IAG Group. Lufthansa, SWISS, and Austrian Airlines share codes within the Lufthansa Group. Delta, Air France, and KLM share codes as SkyTeam partners. Qatar Airways and many airlines offer code share flights on international routes where two airlines effectively operate the same flight under different numbers. Codeshares differ from a direct flight on a single carrier: when two airlines share the same flight, baggage allowance rules and frequent flyer program accrual may differ depending on which airline you booked with, so always check your booking confirmation for the applicable terms.

The Golden Rule: The Operating Carrier Pays

Under EC 261/2004 and UK 261, EU flight compensation on codeshare flights is always the responsibility of the operating carrier - the airline whose crew and aircraft actually operated the flight.

The CJEU confirmed this explicitly: Article 2(b) of EC 261 defines the "operating air carrier" as the airline that performs or intends to perform the particular flight. The marketing carrier has no obligation to pay EC 261 compensation unless it also operated the flight.

In codeshare agreements, airlines may engage in "finger-pointing" when it comes to responsibility - each directing the passenger to the other. The law is clear: the operating carrier is responsible for compensation and care to passengers, while the marketing airline handles customer service aspects such as rebooking options.

If you booked through Air France but KLM operated the flight, claim against KLM. If you booked through British Airways but Iberia operated the flight, claim against Iberia. If you booked through a non European airline but a European airline operated the flight, EC 261 applies.

How to Identify the Operating Carrier

Check your boarding pass first - it shows the operating airline. Look for "Operated by" in the flight details. Most booking confirmations also show the operating carrier when it differs from the marketing airline.

If you are already at the gate, the aircraft registration on the fuselage identifies the airline operating the flight: G- prefix is UK, D- is Germany, F- is France, PH- is Netherlands, OE- is Austria, EI- is Ireland.

If your itinerary shows two flight numbers for the same departure time and route, one is the marketing code and the other is the operating code.

To file a compensation claim, gather supporting evidence including your booking confirmation, boarding passes, and any documentation that confirms the delay or cancellation, then submit it directly to the operating airline's website or claims portal.

How Codeshares Affect Your EC 261 Rights

Whether your codeshare flight is covered by EC 261 depends on the operating carrier and the point of departure - not the airline you booked with. EC 261 covers airline passengers on international flights and domestic flights departing from EU airports, and on flights operated by EU carriers in both directions.

If a non-EU airline books you but a European airline operates the flight, EC 261 applies. If the flight departs from an EU airport regardless of which airline is operating the flight, EC 261 applies. If a non European airline operates a flight originating outside the EU, EC 261 does not apply. Extraordinary circumstances may also exempt airlines from paying compensation even on covered routes.

Airlines participating in codeshare agreements on international routes that depart from European airports are all subject to EC 261 for any flight disruption or canceled flight. Many airline passengers with valid claims miss them because they assume their booking with a non-EU airline means no EU protections apply.

Common Codeshare Compensation Mistakes

Claiming from the wrong airline. Passengers write to the marketing airline rather than the one airline operating the flight. The marketing carrier redirects the passenger, adding weeks of delay.

Assuming the flight is not covered. A passenger books through a non European airline for a European departure and assumes no EU protections apply. If the flight operated by a European airline or departs from an EU airport, EC 261 applies.

Not checking each connecting segment. On a multi-leg journey, different segments may be operated by different airlines. Each has a different operating carrier responsible for any delay.

Accepting the marketing carrier's rejection. "This was not our flight" is a redirection, not a denial. The claim is valid - it just needs to go to the operating carrier.

Codeshare Connecting Flights: How Compensation Works

If all flights are booked on a single reservation (one booking), compensation is based on the total journey distance and the arrival delay at the final destination - regardless of which segment caused the significant delay or which airline operated each segment.

Example: You book London-Frankfurt-Tokyo as a single itinerary. The London-Frankfurt leg (operated by British Airways) is delayed, causing you to miss the Frankfurt-Tokyo connection (operated by Lufthansa). You arrive in Tokyo 5 hours late. Compensation is €600 based on total distance. The responsible airline is British Airways, whose delay on the first flight caused the missed connection.

Separate tickets are treated as separate journeys. If you booked London-Frankfurt and Frankfurt-Tokyo on separate tickets, each is an independent claim.

A delay on the first ticket does not create a claim on the second, even if the same travel plans are affected and more than one airline is involved in the overall trip. When the delay causes you to need a new flight entirely, the operating carrier of the delayed flight is responsible for rebooking - not the marketing carrier.

Frequently Asked Questions About Codeshare Flight Compensation

Who pays compensation on a codeshare flight?

The operating carrier - the airline operating the flight with its own crew and aircraft. If you booked through Air France but KLM operated the flight, KLM pays. The marketing airline has no EC 261 obligation for a single flight it did not operate.

Can I claim EC 261 compensation if I booked through a non-EU airline?

Yes, if the flight operated by a European airline or the flight departed from an EU airport. EU flight compensation depends on the operating carrier and departure point, not the booking airline.

What if I do not know which airline operated my codeshare flight?

Check your boarding pass for "Operated by," or check the aircraft registration. FlyPayout identifies the operating carrier from your booking confirmation or flight number as part of every claim.

Does a codeshare affect how much compensation I can claim?

No. The compensation amount is based on flight distance - €250, €400, or €600 - regardless of whether the particular flight is a codeshare. A delay of more than three hours at the final destination entitles you to the same compensation as any qualifying disruption.

My marketing carrier rejected my claim - what now?

If the airline you booked through says "this was not our flight," your claim is not dead. File with the operating carrier. FlyPayout identifies the correct airline and files accordingly.

Do not let codeshare confusion cost you compensation.

Codeshare flights create real uncertainty about who to claim against - and airlines exploit that confusion. The rule is simple: the operating carrier pays. FlyPayout identifies the right airline, files the claim, and handles the rest.
