United Airlines codeshare claims: identify the operating carrier
A UA flight number does not prove that United owes the claim. Check whether United, Lufthansa, SWISS, Austrian Airlines, Brussels Airlines or another partner actually operated each sector. Operator status can be decisive on a US-Europe journey: a European-operated inbound flight can be covered where a United-operated inbound flight normally is not.

Codeshare outcome table
| Journey beginning in US | Actual operator | Fixed European scope |
|---|---|---|
| Newark-Frankfurt | United | Normally outside EU261 |
| Newark-Frankfurt | Lufthansa | EU261 can apply |
| US-Zurich | SWISS | Relevant European/Swiss protection can apply |
| US-Brussels | Brussels Airlines | EU261 can apply |
| US-Heathrow | United | Normally outside UK261 |
| US-Heathrow | Eligible UK or EU carrier | UK261 can apply |
On departure from Europe or the UK, any carrier can be within territorial scope. The operator still determines who receives the fixed claim.
Where to find operation evidence
Look at:
- the original e-ticket confirmation;
- the phrase below each flight number;
- boarding pass;
- airport departure display;
- aircraft and crew information;
- disruption email;
- reissued itinerary after a change.
Preserve the original before accepting rerouting. A UA-marketed flight can be replaced by a partner-operated service, and the relevant operator may differ between the original cancellation and the transport ultimately flown.
Marketing carrier is not the respondent by default
United may sell the ticket, collect payment and issue a UA code. Lufthansa may perform the aircraft operation. EU261 generally places obligations on the airline that performs or intends to perform the flight.
The marketing carrier may still handle refunds or ticket servicing. Those commercial functions do not automatically make it liable for fixed compensation. Send each request to the party responsible for that remedy and explain the distinction.
Star Alliance itself is not an operating airline and does not pay passenger claims.
Inbound coverage changes with the operator
United is a US carrier. A United-operated Chicago-Frankfurt flight beginning in America normally has no EU261 fixed amount. If Lufthansa actually operates the same marketed itinerary, inbound EU261 coverage can exist because Lufthansa is an EU carrier.
This is one of the most important checks for passengers rejected with "flight departed outside Europe." The statement may be right for United operation and wrong for a European partner operation.
Conversely, an LH flight number operated by United remains a non-EU operation for the inbound scope test. Logo and code do not replace the aircraft operator.
Outbound Europe and UK journeys
Frankfurt-US departure can be covered whether United or Lufthansa operates it. Heathrow-US departure can be covered whether United or an eligible partner operates it. The operator affects respondent, not the basic any-carrier outbound rule.
For a one-booking connection, use initial departure and final destination. If a partner feeder and United long-haul sector form one journey, preserve every operated-by entry and identify which flight caused final delay.
C-561/20 shows that United can be liable as the non-EU operating carrier for an EU-origin journey booked with Lufthansa. The contracting partner does not erase United's operational role.
That judgment involved United operating the complete journey. When different airlines perform the connecting sectors, do not assume the last operator is the only possible respondent. C-502/18 allowed a claim against the Community carrier that performed the first flight where its non-EU code-share partner caused the long final delay on the second flight.
Rerouting across Star Alliance
After a covered cancellation, ask for earliest comparable rerouting. United may offer its own service or a partner. Availability and operational feasibility matter; alliance membership does not guarantee a seat, but the airline should consider reasonable alternatives rather than limiting the search without explanation.
Document the specific partner flight and seats before self-booking. If rerouting changes cabin, preserve the original and replacement cabin for a downgrade calculation.
Accepting partner rerouting does not automatically settle fixed compensation against the original operating carrier.
Refund and expenses can involve different parties
The ticket issuer may process unused-fare reimbursement. The original operating carrier handles fixed compensation. United Customer Care may receive expenses when United managed the disruption, but a partner can dispute allocation.
Label each sum and attach the instruction directing you to a particular party. Do not allow repeated referrals to consume limitation time. Submit protective claims where operator evidence is genuinely ambiguous and ask each airline to state its position.
An OTA adds another servicing layer but does not become the operating carrier.
Wet lease is not ordinary codeshare
When one airline hires an aircraft and crew under a wet lease while retaining operational responsibility for the marketed service, EU guidance treats the hiring airline as the operating airline for Regulation 261. That differs from a genuine codeshare where the partner decides and performs the flight.
Look at the full notice rather than assuming that a different paint scheme changes liability. Ask who decided to operate the service and under whose operational responsibility it ran.
A claim method
- Build a segment table with marketing and operating carrier.
- Mark the sector that caused the disruption.
- Apply route scope from initial departure.
- Calculate final delay at the last ticketed airport.
- For one disrupted flight, address fixed compensation to its operator; for a journey split between carriers, apply the connecting-flight case law before selecting the respondent.
- Send unused-fare servicing to the ticket issuer where appropriate.
The United form guide helps keep those channels separate.
Example: United ticket, Lufthansa aircraft
A traveller buys a UA-coded Newark-Frankfurt flight from United. The confirmation says operated by Lufthansa. The flight arrives four hours late because of a routine technical problem. Even though the journey begins in the US, Lufthansa's EU status can bring it within EU261. The fixed claim goes to Lufthansa as operator.
If the confirmation instead says operated by United, EU261 normally does not apply to that direction. DOT refund or other remedies must be assessed on their own triggers.
FAQ
Does a UA flight number mean United operated the flight?
No. It can be a codeshare performed by Lufthansa, SWISS, Austrian, Brussels Airlines or another partner.
Who pays EU261 on a codeshare?
The operating carrier is normally central, but a connection split between different airlines needs a separate respondent analysis. C-502/18 shows that the carrier performing the first covered flight can sometimes answer for delay caused by its code-share partner later in the journey.
Can Lufthansa operation cover a US-Europe flight?
Yes. A Lufthansa-operated inbound journey can enter EU261 because Lufthansa is an EU carrier.
Does Star Alliance pay compensation?
No. Star Alliance is a network, not the operating airline responsible for a disrupted flight.
Is a wet lease treated like a codeshare?
Not automatically. EU guidance can treat the airline retaining operational responsibility as the operator despite another airline supplying aircraft and crew.
