How to book the ÖBB Nightjet, step by step
ÖBB Nightjet is Europe’s largest sleeper network, running out of Vienna to Germany, Switzerland, Italy, the Benelux, Poland, Hungary and Croatia. It is also the network most first-time night-train travellers end up booking, so here is exactly how to do it without overpaying or missing out on a private cabin.
When booking opens
Nightjet releases each route for sale around 180 days — roughly six months — before departure. That window matters more than on a normal train, because the cheapest seats and couchettes, and especially the private ensuite cabins, sell out well ahead of departure. If a specific date matters to you (a festival, a wedding, peak summer on the Vienna–Split line), it is worth marking that six-month date and booking as close to release as you can.
Where to book
Book directly at nightjet.com. It is Nightjet’s own booking engine, shows the real-time availability across all cabin classes, and is the most reliable place to see which fare tier is actually left on a given date. Third-party aggregators can also list Nightjet routes, but for a network with this much day-to-day variability, going direct gives you the clearest picture.
Choosing seat, couchette, sleeper or private
Nightjet sells four cabin types, and the right one depends on budget and how much privacy you want:
- Seat — a reclining seat in a shared car, the cheapest option and the lowest sleep quality of the four.
- Couchette — a bunk in a 4–6 berth compartment, shared unless you book out the whole compartment. The classic budget night-train experience.
- Sleeper — a proper made-up bed in a 1–3 bed compartment, usually with an in-room washbasin and breakfast included. This is the standard mid-range pick.
- Private / Comfort Plus — an ensuite compartment with its own shower and toilet, on Nightjet’s new-generation carriages rolling out since 2023. It is the most comfortable option and also the one with the least availability, so book it early.
On the newest trains, Comfort Plus cabins even come with mini-cabin layouts and individual climate control — but this rolling stock is still being rolled out route by route, so don’t assume every departure on a given line has it.
The rail pass reality
Eurail and Interrail passes are accepted on Nightjet, but only partially, and this catches a lot of first-time pass holders out. A compulsory reservation fee and a couchette/sleeper supplement apply on top of the pass itself, and private Comfort/Comfort Plus cabins have a limited allocation for pass holders — meaning even with a valid pass, you may not be able to get a private cabin on a popular date if the pass quota is already full. If a private cabin matters to you, book it as early as the 180-day window allows.
Practical tips before you travel
- There’s no formal check-in. You board at the platform and a conductor checks your ticket and ID at or after departure.
- Baggage is free in the cabin or on the overhead rack, with no strict weight limit, but you’re expected to be able to manage it yourself.
- Refund rules depend on fare tier — the cheapest promotional fares are largely non-refundable, while flexible fares can be changed for a fee.
- Check the route is actually running as booked. Nightjet’s network shifted in 2025–2026: the Paris–Vienna and Paris–Berlin services were discontinued in December 2025, along with the Munich/Vienna–La Spezia routes, and several German routes have been diverted via Munich during 2026 engineering works between Nuremberg and Linz. None of this should stop you from booking, but it is worth a quick check on nightjet.com close to departure.
Booked well ahead, on the right route, Nightjet is genuinely one of the best-value ways to cross Europe overnight. Booked last-minute hoping for a private cabin, it usually isn’t — so treat the 180-day mark as the real start of your trip planning.
