Do I need to book a specific train departure time?
No, CAT tickets are not tied to a specific time slot or even a specific day. Standard online tickets are valid for six months from the date of purchase, allowing you to board any CAT train during that period. They depart every 30 minutes from both the airport and Wien Mitte, with a non-stop journey time of 16 minutes.
How does the City Check-in at Wien Mitte work?
If you have a valid CAT ticket, you can check your luggage and receive your boarding pass at the CAT terminal in Wien Mitte (Landstraße) for many airlines, including Austrian, Lufthansa, Swiss, and Eurowings. This service is available from 24 hours up to 75 minutes before departure, allowing you to travel to the airport hands-free.
Are children required to have a ticket for the CAT?
Children under the age of 15 travel free of charge on the City Airport Train. You do not need to purchase a ticket for them, but you should carry a valid ID to verify their age if requested by the train attendant during the journey.
Does a CAT ticket include travel on Vienna's subways or trams?
A standard CAT ticket only covers the non-stop transfer between the airport and the Wien Mitte station. It does not include travel on Vienna's city-wide public transport (U-Bahn, trams, or buses) unless you specifically purchase a 'CAT + City Ticket' combo or already hold a valid Wiener Linien pass.
What is the difference between the CAT and the S-Bahn S7 or Railjet?
The CAT is a premium, non-stop service to Wien Mitte (16 mins, from €15.90). The S-Bahn S7 is the budget alternative (€4.40), taking 25 minutes with multiple stops. The ÖBB Railjet also costs €4.40 and takes 16 minutes, but it arrives at Vienna Main Station (Wien Hbf) rather than the central Wien Mitte hub.
How long is my CAT ticket valid after purchase?
Standard CAT tickets purchased online are typically valid for six months from the date of purchase. This provides flexibility if your flight is delayed or if you decide to change your travel day within that period.
Where do I find the CAT platforms at the airport and in the city?
At Vienna Airport, follow the bright green 'CAT' signs from the arrivals hall to the lower station level. In the city, the CAT terminal is located at the Wien Mitte (Landstraße) station, which is directly connected to the U3 and U4 subway lines.
