Public transportation options at Vienna International Airport:  On the first level of the Terminal complex (Arrivals), as well as from Carpark 4, you can access the S-Bahn (Rapid Rail) & the CAT train by a covered walkway  (the present underground railway station will be expanded to connect to Bratislava, Slovakia). The CAT bus stop is on the opposite side and guarantees you a seat if you reserve ahead. 

1. The S-Bahn to Vienna's city center
runs every half hour,  takes 25 mins. Tickets machines are on the train platforms.
2. The City Airport Train (CAT) runs non-stop to the City Air Terminal, which is only a 16-minute ride from St. Stephan's Cathedral, accessible by tram, subway, bus or taxi.   A CAT counter for tickets is on the ground level, at left.
3. Vienna Airport Lines connects Airport West with the main Vienna transport hubs. 
4. Regional buses run to Vienna Donauzentrum (via Vienna Kaisermuhlen VIC) taking 40 mins; and to Westbahnhof (train station West) via Vienna-Dorfelstrasse & Meidling train station taking 45 mins.
