Almost every guide still says take the S7 to Wien Mitte. Since 7 September 2026, works on the S-Bahn main line mean the S7 terminates at St. Marx, outside the centre, and even the CAT is running as a coach. From St. Marx you continue by tram 18 or 71, or bus 74A to Landstraße. The REX7 and the Railjet still reach Wien Hbf — the Railjet non-stop in 15 minutes.
The City Airport Train runs the same corridor and, since the closure, as a coach rather than a train, yet it still costs €14.90 one way against €5.50 for the ÖBB train. It is no longer the fastest way into town — the Railjet beats it to the main rail hub — it only goes to Wien Mitte, and its city check-in is suspended until the end of October 2027.
Wiener Linien's 24-hour ticket covers zone 100 (the city) only. The airport sits in the surrounding zone, so you must add the €2.30 outer-zone ticket for €12.50 total, and the same applies to the 7-day and 31-day tickets. There has been no 48-hour or 72-hour ticket since 1 January 2026 — for two or three days buy two 24-hour tickets (€20.40).
The airport is outside the City of Vienna's regulated taxi tariff, so a trip to town is legally a freely priced ride — exactly what touts exploit. A licensed rank taxi on the meter is normally €40–55; anyone quoting far above that, or refusing to run the meter, is ripping you off. Drivers who approach you inside the terminal are not the official rank.
Older guides quote €8 for the Vienna Airport Lines (VAL) and still name viennaairportlines.at, which now redirects to viennaairportbus.com. The operator is ÖBB Postbus and the full fare is €11 one way / €20 return — dearer than the €5.50 train and slower, at about 40 minutes to Westbahnhof.
