Your Interrail or Eurail Pass covers your train travel across Europe, but it does not include seat reservations. Most high-speed, international, and all night trains require a separate paid reservation. Fees range from around €2 to €43 depending on the operator and route. This guide covers which trains need reservations, what they cost in EUR, and where to book them.

Which trains require a seat reservation?

Not every train needs one. The rule follows train type, not just country.

High-speed trains almost always require reservations for pass holders. France, Italy, and Spain are strictest: TGV, Frecciarossa, Eurostar, and AVE trains all carry compulsory pass-holder reservations. Some trains sit in between. The ICE between Germany and the Netherlands, for example, requires a reservation only in summer (late June to late August); it is optional the rest of the year.

Night trains always require a reservation. You cannot board with just your pass. They also offer three accommodation types at different fee levels: a reclining seat, a couchette (a shared bunk-bed compartment, usually four or six berths), or a sleeper cabin. Couchettes and sleepers cost more than a seat reservation and can sell out well before departure.

Regional and slower trains in most countries can be boarded on your pass without a reservation. This includes most local and regional services in Germany, Austria, Switzerland, Belgium, and the Netherlands. Board and find a seat.

Before you plan any high-speed or night train leg, check the Interrail or Eurail timetable. It shows whether your specific train requires a reservation and what it costs.

Italy: Italo does not accept rail passes

This is the single most important thing to know about Italy.

Italy has two high-speed operators on the main corridor between Milan, Florence, Rome, and Naples: Trenitalia (Frecciarossa and Frecciargento) and Italo (NTV). Trenitalia accepts Interrail and Eurail passes and requires a seat reservation. Italo does not accept Interrail or Eurail passes. Boarding an Italo train with only your pass means paying a full commercial fare.

When travelling high-speed in Italy with a pass, use Trenitalia. Do not assume Italo follows the same rules.

What does a reservation cost?

Fees are in EUR and vary by operator, route, and class. The table below lists the key pass-holder reservation fees as sourced from Interrail.com. These are indicative and subject to change.

Always check the current fee in the timetable before you book. Fees can change, and prices via travel agents may differ from the amounts listed here.

A €2 booking fee per passenger per train applies when you reserve through the Interrail or Eurail online system.

How to book

Online via Interrail.eu or Eurail.com

Log in or create an account, add your pass details, and search for your train. The system shows which trains require reservations, what they cost, and which seats are available. It covers most of the trains where reservations are needed.

Some trains are not available through the online reservation system. For those, try the operator’s website. First confirm the operator accepts pass-holder reservations.

For Eurostar: pass-holder reservations cannot be booked through Eurostar’s own website. Eurostar.com sells commercial tickets and has no pass-holder fare. Book via Interrail.eu, Eurail.com, or an approved agent.

Via the Rail Planner App

The Rail Planner App is the fastest way to check reservation requirements for a specific train. You can also complete the reservation directly within the app for most supported operators. Not every operator is bookable through the app, but it is useful for quickly confirming what you need before you get to the booking step.

At the station

You can buy seat reservations at ticket offices and self-service machines at most major European stations. Bring your pass and know your train number and travel date before you arrive.

Booking at the station avoids the €2 per-person online booking fee, which adds up across several trips. The trade-off is availability. For trains like Eurostar and TGV, pass-holder allocations can sell out weeks or months in advance. Waiting until you arrive at the station may leave you without options.

Spain: Renfe pass-holder reservations (from April 2025)

From 2 April 2025, Renfe high-speed trains became bookable for pass holders through Rail Europe’s platform. Interrail and Eurail Global Pass holders can now reserve seats on AVE, Alvia, Euromed, and some Intercity services through the standard reservation system. Reservations are compulsory. The fee is €25 (Elige class) or €28 (Elige Confort class). Before this change, booking Renfe pass-holder reservations required going directly to Renfe or a Spanish travel agent.

Booking tips

Eurostar: book early, the pass-holder allocation is fixed

Eurostar allocates a set number of seats on each service to pass holders. When those seats are taken, there is no pass-holder reservation available, even if the train still has commercial seats for sale. It is not a demand issue. It is a fixed quota. The Amsterdam to Paris Eurostar fills its pass-holder allocation fastest. Book as soon as your dates are confirmed, and in summer, that means months ahead.

If the pass-holder allocation is sold out on your preferred departure, check other times or consider travelling via Brussels, which often has more availability.

Night trains: decide on accommodation before you book

On Nightjet and other night trains, seats are cheapest but most people want at least a couchette. Couchette places go before seats, and sleeper cabins go first. If you have a fixed departure date, book the accommodation category you want early. A seat is still a valid booking if nothing else remains, but it is not a restful way to cross a long route overnight.

Always carry both your pass and your reservation

Ticket inspectors on trains with compulsory reservations check both. Your pass shows you have travel rights. Your reservation shows you have a specific seat. Having only one may not be sufficient.

What to expect when you receive a reservation

E-tickets are standard for Italy, France, Austria, Switzerland, Germany, and the Benelux countries. These arrive by email after booking, usually within minutes. Some other countries still send reservations as paper tickets by post.

Your confirmation shows the train number, departure time, car, and seat. Check these details before your travel day.
