Booked Through Trainline or Omio? Who Do You Claim Compensation From?

Third-party booking platforms have made buying train tickets across Europe far easier. Trainline, Omio, SNCB Connect, and others aggregate routes and fares from dozens of operators into a single checkout. But when your train is delayed and you need to claim compensation, the booking platform drops out of the picture entirely. The claim goes to the operator, not the retailer.

Why you claim from the operator, not the booking platform

Third-party booking platforms are ticket retailers, not carriers. Under EU Regulation 2021/782, the obligation to pay delay compensation sits with the railway undertaking — the company that actually operated the train. Trainline and Omio earn a commission on each ticket sold; they do not take on the carrier's legal obligations in return.

This is not a technicality designed to make your life harder. It is the same logic that applies when you buy a flight through Skyscanner: if the flight is delayed, you claim from the airline, not from Skyscanner.

The practical consequence is that any message sent to Trainline or Omio's customer service asking for delay compensation will be redirected to the operator. Going directly to the operator from the start saves time.

"Railway undertakings and ticket vendors shall inform passengers of their rights and obligations under this Regulation." — EU Regulation 2021/782, Article 10

Note that Article 10 places the information obligation on both railway undertakings and ticket vendors. Booking platforms are required to tell you that your rights exist. But paying out on those rights remains the operator's responsibility.

How to identify the right operator

Your booking confirmation from Trainline or Omio will list the train operator for each leg of your journey. Common operators you may need to claim from include:

• DB (Deutsche Bahn): — German domestic and international services
• SNCF: — French domestic and Eurostar/Thalys-branded services on the French side
• Eurostar: — London to Paris and Brussels services
• Thalys / Eurostar International: — high-speed services between Belgium, France, Germany, and the Netherlands
• SJ: — Swedish domestic services
• NS (NS International): — Dutch domestic and cross-border services
• Renfe: — Spanish domestic services
• Trenitalia: — Italian domestic and international services

If your confirmation does not clearly state the operator, the train number is a reliable clue. DB trains use ICE, IC, and EC prefixes; SNCF uses TGV; Eurostar trains have ES prefixes.

Does your Trainline or Omio booking reference work with the operator's claim form?

This is one of the most common practical questions passengers face. The answer depends on the operator and the type of ticket.

For e-tickets and digital tickets: Most major operators now accept third-party booking references on their claim forms. DB's compensation portal, for instance, accepts any ticket number printed on the PDF or displayed in the app, regardless of where it was purchased. The key field is usually the ticket number or order reference printed on the document itself, not the Trainline or Omio order number.

For print-at-home and mobile tickets: These typically carry an operator-issued ticket number alongside the third-party booking reference. Use the operator's ticket number on the claim form.

If the claim form rejects your reference: Call or email the operator's customer service with your booking confirmation attached. They can usually look up your journey using passenger name, travel date, and route, then process the claim manually.

In rare cases, particularly with some legacy booking integrations, the operator may not be able to locate your booking in their system using a third-party reference. TrainOwed handles this scenario regularly and can cross-reference bookings with operator systems.

What happens with multi-operator journeys?

Booking a journey through Trainline or Omio often means a single ticket covering trains run by two or more operators. A London to Cologne journey, for example, might involve Eurostar from London to Brussels and a DB ICE from Brussels to Cologne.

For compensation purposes, EU 2021/782 allows you to claim from any of the operators involved in the journey. You do not need to calculate exactly which operator caused the delay if the total delay at your final destination meets the 60-minute threshold. In practice:

• If the Eurostar was delayed and you missed your ICE, claim from Eurostar, as their service originated the problem.
• If the ICE itself was delayed independently, claim from DB.
• If both were late, you can claim from either, but the compensation is calculated on the combined ticket price for the full journey.

Operators sort out any internal cost recovery between themselves. As a passenger, you have one claim to make and can direct it to whichever operator is most convenient.

Split-ticket bookings: a special case

Some third-party platforms offer split ticketing, where your journey is fulfilled by two or more separate tickets at a lower combined cost. This is common on UK domestic routes through platforms like Trainline.

Split-ticket journeys do not create a single contract with a final destination. Each ticket is a separate transaction, and each delay claim must be submitted separately to the relevant operator for that leg. Missing a connection on a split ticket does not give you the same rerouting rights as a through ticket.

If you see multiple separate tickets in your Trainline booking, check whether the connection time between them is realistic and whether you would be comfortable claiming each leg independently if delays occur.

Refunds on third-party bookings

Delay compensation is separate from ticket refunds. If your train is cancelled and you want a refund rather than compensation, the refund process runs through the operator, but the practical steps depend on how you booked.

For Trainline bookings, most operator-issued e-tickets can be refunded directly through the Trainline app. Trainline acts as a retailer here and processes the refund on the operator's behalf. For Omio, the process is similar, though Omio recommends contacting customer service for cancelled journeys.

Delay compensation (the 25% or 50% payment under EU 2021/782) is always handled directly with the operator, even if the refund for a cancelled train goes through the booking platform. These are two separate processes under two separate parts of the regulation.

How TrainOwed handles third-party bookings

TrainOwed accepts claims for journeys booked through any platform — Trainline, Omio, SNCB Connect, or direct. You upload your booking confirmation, TrainOwed identifies the operator, and submits the claim on your behalf. If the operator's system cannot match a third-party reference, TrainOwed resolves this directly with the operator's claims team.

For multi-operator journeys where responsibility is disputed, TrainOwed manages the cross-claim process and ensures you receive the full compensation you are entitled to from the appropriate operator.
