Brussels Airlines codeshare claims: identify the operating carrier
Short answer: the airline whose aircraft and crew actually perform the disrupted flight is normally responsible under EU261 and UK261. An SN flight number, Brussels Airlines ticket stock or Lufthansa Group booking page does not by itself prove operation. Check “operated by” on the e-ticket and boarding pass, then address fixed compensation to the correct legal company.

Marketing carrier versus operating carrier
| Booking clue | What it proves |
|---|---|
| SN flight number | Brussels Airlines markets the service |
| Ticket issued on Brussels Airlines stock | Ticketing relationship, not necessarily operation |
| “Operated by Brussels Airlines” | Strong evidence Brussels Airlines performs it |
| Partner logo on boarding pass | Useful, but read the legal operator wording |
| Aircraft paint | Not conclusive in wet-lease arrangements |
| Crew and operational control | Central to actual-carrier analysis |
The Court of Justice in Wirth linked “operating air carrier” to the entity that decides to perform a flight, fixes its itinerary and creates an offer of carriage. A company that only leases aircraft and crew may not be the operator where another airline retains that decision and responsibility.
Where to find the operator
Start with the original confirmation, then compare the boarding pass and airport display. Look for the full legal or trading name after “operated by.” Record the two-letter code and flight number. If the flight is cancelled before boarding passes exist, save the booking's operator line and any airline notification.
After rerouting, repeat the check for every new segment. The operator of the replacement does not necessarily become liable for the original cancellation; it can be performing only the transport remedy.
Lufthansa Group is not one airline
Brussels Airlines, Lufthansa, SWISS, Austrian Airlines, Discover Airlines and other group companies remain separate legal carriers. Shared websites, service desks, Miles & More and booking systems do not merge liability.
If a Lufthansa-operated feeder causes a missed Brussels Airlines connection, the compensation analysis starts with Lufthansa as the causal operator. If Brussels Airlines cancels its long-haul segment and reroutes via Lufthansa, Brussels Airlines can remain responsible for its original event while Lufthansa must perform the replacement properly.
Do not address a demand to “Lufthansa Group” without naming the company. A payment team needs the defendant and sector.
Star Alliance and non-group partners
Star Alliance membership facilitates through tickets and rerouting but does not create collective liability. United, Air Canada or another partner can sell or operate an SN-coded flight. The operator rule still applies.
For an inbound flight from a third country, operator identity can decide whether EU261 applies. A Brussels Airlines-operated Africa-to-Belgium service can be covered because the airline is European. A non-EU partner-operated return carrying an SN code does not inherit that status from marketing.
Wet lease and aircraft markings
In a wet lease, one company supplies aircraft and crew while another may retain commercial and operational responsibility. Do not conclude from livery alone. Review booking wording, safety announcements, boarding pass and the company that decided to perform the route.
If operator details conflict, ask Brussels Airlines to identify the entity acting as operating air carrier under Article 2(b), including its legal name and contact route. Keep photographs of aircraft registration and documents as supporting evidence, not the sole test.
Connected-flight liability
One protected booking can involve several operators. Record which event caused the late final arrival. Court of Justice cases permit claims in connected travel under specific circumstances, but they do not justify billing every airline for the full amount.
Example: a Brussels Airlines feeder arrives late at BRU and the passenger misses a partner-operated onward service. If the feeder caused a qualifying final delay, Brussels Airlines is the initial compensation target. The partner still owes duties for any separate disruption it causes.
If the first sector operated on time and the partner cancels the second, address that event to the partner. The ticket seller can remain relevant for refund processing without becoming the operating carrier.
Baggage uses an additional framework
The Montreal Convention can permit action against the contracting carrier or actual carrier in appropriate cases, and baggage tracing often begins with the last carrier at destination. This is broader than the EU261 operating-carrier rule. Do not redirect a baggage complaint solely because the fixed delay claim belongs elsewhere.
Keep every bag tag and Property Irregularity Report. Identify who accepted the bag, who performed each sector and which airline handled the final arrival.
How to correct a claim sent to the wrong company
- Preserve the first submission and response.
- Obtain the boarding pass or operator confirmation.
- Write to the actual carrier with the complete itinerary and original submission date.
- Explain the earlier identification error without asserting group liability.
- Ask the first company to preserve or transfer relevant operational data where appropriate.
- Track the deadline independently; correspondence with the wrong entity may not protect it.
Brussels Airlines' current Conditions of Carriage specify a one-year EU261 action period under Belgian law. Another operator can have a different governing rule, so prompt correction matters.
Evidence statement for the form
Use a direct sentence: Flight SN[ ] was marketed by Brussels Airlines and operated by [legal airline], as shown on the attached boarding pass. Then identify the disruptive sector and final arrival. If Brussels Airlines truly operated it, state that and attach the operator line before discussing the SN code.
The partner-rebooking guide separates original liability from the carrier used after disruption.
FAQ
Does an SN flight number mean Brussels Airlines must pay?
No. It proves marketing. EU261 liability normally follows the airline that actually operates the disrupted flight.
Is Lufthansa responsible because it owns Brussels Airlines?
Not for that reason alone. Each company remains legally distinct and responsibility follows the relevant operator and remedy.
Who pays when another airline operates the replacement flight?
The replacement carrier performs rerouting, while liability for the original event can remain with the original operating airline.
Does aircraft paint identify the carrier in a wet lease?
Not conclusively. Examine who decided and undertook to perform the flight, plus the contractual operator wording.
Is the rule the same for baggage?
Not exactly. Montreal liability can involve contracting and actual carriers, so preserve the complete baggage journey and tracing record.
