Short answer
EU passenger rights are mode-specific. Regulation 261/2004 covers qualifying flights; Regulation 2021/782 covers rail; Regulation 181/2011 covers bus and coach; and Regulation 1177/2010 covers sea and inland-waterway travel. A journey containing several modes does not automatically become one protected EU connection.
Within a mode, the booking structure matters. Flights booked as one connecting itinerary can be treated as a whole even where different airlines operate the legs. A rail through-ticket can create one transport contract across successive services. Separately purchased tickets normally leave each operator responsible only for its own leg, unless the seller failed to give required information or contract, package-travel or national law creates broader liability.
The immediate remedy usually comes from the operating carrier or railway undertaking, while terminal or station managers have particular assistance duties. A ticket seller, package organiser or intermediary may owe separate contractual or statutory duties. Internal recourse between businesses cannot reduce the passenger's rights.
Map contracts, operators and modes first
For every leg, record the mode, origin and destination, scheduled times, operating undertaking, contracting seller, reservation number and whether a single price and ticket covered the sequence. “One trip” in a travel app may still be several legal contracts.
Four roles commonly differ:
- the operating carrier actually performs an air, bus or sea service;
- the contracting carrier or railway undertaking sold or undertook transport;
- the ticket vendor or intermediary arranged the booking; and
- a terminal, station or infrastructure manager controls facilities and some assistance.
The passenger should direct the regulatory claim to the actor named by the relevant regulation, without surrendering contractual claims against others.
Air: one reservation can connect several operating airlines
Regulation 261/2004 generally covers passengers departing from an EU airport, regardless of airline nationality. It also covers arrival in the EU from a third country when the operating air carrier is an EU carrier and equivalent benefits were not received in the third country.
The “operating air carrier” performs or intends to perform the flight under a passenger contract or on behalf of the contracting party. It owes denied-boarding, cancellation, long-delay, care, rerouting and standardised-compensation duties. The airline that sold the itinerary, a tour operator and a booking platform may have additional obligations, but code-share branding does not replace the operating carrier.
Obligations under Regulation 261/2004 “may not be limited or waived” by a contract term. —
Connecting flights booked as a single unit are assessed by reference to the final destination. In Folkerts, C-11/11, compensation turned on arrival three hours or more late at the final destination even though the departure delay on the first leg was below the Regulation's compensation threshold.
Where one airline performs the EU first leg and a non-EU airline performs a later leg outside the EU under one reservation, EU law can still allocate passenger-facing responsibility to the EU operating carrier. In České aerolinie, C-502/18, the EU carrier operating the first leg could owe compensation for a long final-arrival delay caused on the connecting flight operated by another airline. It retained a right of recourse against the responsible business.
Separate reservations usually break this regulatory connection. If the first airline delivers its own passenger late and the passenger misses a separately contracted flight, Regulation 261 may compensate the first flight's qualifying delay, but does not automatically make that carrier reroute the second ticket.
Rail: through-tickets determine the protected journey
Regulation 2021/782 applies to rail journeys and services within the Union, subject to defined national exemptions for certain urban, suburban, regional or third-country services. Core rights cannot be removed merely by an exemption.
A through-ticket represents a transport contract for successive railway services run by one or more railway undertakings. Delay is measured to the destination under that contract. The responsible railway undertaking must provide information, reimbursement or continuation/rerouting, assistance and delay compensation where thresholds are met.
A “through-ticket” evidences “a transport contract concluded for a sequence of railway services”. —
Where tickets are sold in one commercial transaction by a railway undertaking, they are generally presumed to be a through-ticket unless clearly stated otherwise. Vendors and tour operators selling separate tickets must inform the passenger that the tickets are separate before purchase. Failure to do so can make them liable for reimbursement and assistance comparable to a through-ticket disruption.
Railway undertakings remain responsible for transport; station managers have accessibility, information and contingency roles. A passenger should preserve the itinerary, ticket format and pre-contract statements because they decide whether a missed connection falls within the through-ticket remedy.
Bus and coach: distance and scheduled-service status matter
Regulation 181/2011 principally covers passengers using regular services where boarding or alighting is in the EU. Its full cancellation, delay and terminal-assistance regime generally applies where the scheduled service distance is at least 250 kilometres. A smaller core—including non-discrimination, accident-related rights and disability protections—applies more broadly. Occasional services have a narrower set of rights.
The carrier normally owes continuation, rerouting, reimbursement, information and compensation where the Regulation specifies. Terminal managing bodies share particular assistance and disability duties. If a journey changes between two separately ticketed coach operators, the first carrier is not automatically responsible for the second missed service. A single contract or package may change that.
Sea and inland waterways: embarkation, arrival and carrier identity
Regulation 1177/2010 covers passenger services departing from an EU port. It also covers services arriving at an EU port from outside the Union where the service is operated by a Union carrier, and cruises whose port of embarkation is in the EU, subject to stated exclusions for small vessels, very short excursions and certain heritage ships.
The carrier owes cancellation and delay information, assistance, rerouting or reimbursement and arrival-delay compensation. A “performing carrier” that actually performs all or part of the service may share responsibility under the Regulation. Port-terminal operators have designated information and disability-assistance functions.
A ferry included in a rail-and-sail product is not automatically governed as one journey by either mode's passenger regulation. Each regulation covers its leg unless the commercial arrangement creates a through contract, package or other combined liability.
Multimodal connections have no general missed-connection guarantee
EU law does not yet supply a universal compensation rule for every air–rail–bus–sea chain. If a delayed train causes a missed separately booked flight, the rail regulation addresses the rail delay and the air regulation addresses the flight, but neither automatically treats the other mode's ticket as its final destination.
Three other legal sources may fill the gap:
- a contractual connection guarantee offered by the seller or transport undertaking;
- Directive (EU) 2015/2302 where the combination is a package, making the organiser responsible for performance of included travel services; or
- national contract, consumer or damages law, provided it does not reduce mandatory EU rights.
A linked travel arrangement under package law is not necessarily a package and has narrower protection. Marketing the journey as protected, taking a single payment and selecting services before one contract is concluded can affect classification.
Who should receive the claim?
For a flight, claim first from the operating carrier identified for the disrupted leg, noting the single-reservation final destination. For rail, identify the railway undertaking and whether the documents form a through-ticket; include the vendor if it failed to disclose separate tickets. For bus or sea, claim from the carrier and use the terminal body's process for failures within its role. For a package, notify the organiser as well.
Businesses cannot force passengers to resolve internal allocation before receiving a remedy. Regulations preserve carriers' rights to seek reimbursement from tour operators, other carriers, infrastructure managers or third parties.
Evidence and enforcement
Keep confirmations, ticket numbers, boarding documents, actual arrival times, cancellation messages, receipts, alternatives offered and the names of operating companies. Submit the carrier's complaint first where required, then use the designated national enforcement or complaint body and courts. Limitation periods and complaint deadlines differ by regulation and national procedure.
Conclusion
The decisive questions are not simply how many operators were involved, but whether the relevant mode regulation applies and whether the legs formed one protected booking or through-ticket. Single air reservations and rail through-tickets can carry protection to the final destination. Separate multimodal tickets usually remain separate, unless package law, seller information failures or contract terms create an additional remedy.
