The CAT runs at 30-minute intervals daily from 6:07 a.m. to 11:37 p.m. between the city center (Wien Mitte/Landstraße station) and the airport.
The Central Wien Mitte station also connects with the U3 and U4 subway lines for onward journeys within Vienna. Wien Mitte is located on the edge of the old town/First District, making it a convenient landing spot.
More information and how to purchase tickets ahead of time can be found. HERE
Getting back to the airport from the city center: CAT passengers have the option of using the City Check-In facility at the City Air Terminal at Wien Mitte. Assisted check-in desks and self-service machines are available for check-in with or without luggage. City Check-In is available every day between 5 a.m. and 10:45 p.m. for selected airlines. You can check in between 24 hours and 75 minutes before departure, depending on the airline. Information on which flights are handled at the City Air Terminal can be found in the City Check-In overview.
Having checked in with the selected airline at the City Air Terminal in Wien Mitte, passengers can drop off their bags by presenting a valid CAT ticket and receive their boarding pass in return. This eliminates the need for check-in and baggage drop at the airport, allowing travelers to go directly to security.
