The fastest way into Vienna from Schwechat Airport is the sleek, double-decker City Airport Train. From the airport to the center of the city, the CAT takes only 16 minutes, and trains operate daily every 30 minutes between 6 am and 11 pm. The cost is €12 one way and €19 round-trip. Tickets can also be purchased online at www.cityairporttrain.com for a reduced price. But the cheapest way to get into town from the airport is the S7 train, called the Schnellbahn, which shuttles twice an hour between the station beneath the airport and the Wien-Mitte/Landstrasse station; the one-way fare is €4.40, and it takes about 20 minutes. Your ticket is also good for an immediate transfer to your destination within the city on streetcar, bus, or U-Bahn.
Another cheap option is the fleet of buses operated by Vienna Airport Lines, which has separate routes to the city center at Schwedenplatz (20 minutes) and to the Westbahnhof (45 minutes). Buses operate every 30 minutes between 5 am and 12:30 am, and the fare is €8 each way and €13 round-trip.
If convenience is your priority, Airport Driver has private cars to the airport; one way is €35, and you must reserve at the Tourist Info desk, open 7 am to 10 pm. A regular taxi between the airport and the city center will charge around €40.
