Dogs may only be taken along on an ÖBB Nightjet if you book an entire compartment.
The ÖBB Nightjet ticket for dogs costs an additional € 29.- and is available on the train, by phone from the ÖBB customer service at 0043 5 1717 or at the ÖBB ticket counters. Service dogs travel free of charge and do not need to wear a muzzle. Trips within Austria are subject to ÖBB’s terms and conditions.
On trains operated by the Nightjet partners MAV (Hungarian railway), PKP (Polish railway) and ČD (Czech railway), dogs are unfortunately not allowed in couchette and sleeper cabins.
