Getting from Vienna Airport into the city changed in 2026. The famous CAT airport train is temporarily a bus, while S7 suburban trains no longer run directly to Wien Mitte. You can still reach Vienna easily, but the right route depends on where you are staying. Compare the final stop, not just the advertised journey time.
Relevant recommendation: read Vienna’s official 2026–27 airport transport update. The temporary S7 and CAT arrangements affect route choice; confirm the current connection before travelling.
Why airport transfers changed in 2026
Vienna’s official airport travel update says a central S-Bahn section closed on 7 September 2026, with works expected through October 2027. Airport trains consequently cannot make their former stops at Rennweg and Wien Mitte. CAT replacement coaches began on 24 August 2026. Advice promising a direct S7 to Wien Mitte or a 16-minute CAT train describes the old network, not the current service.
Railjet or REX7: a practical arrival at Hauptbahnhof
ÖBB Railjet and InterCity services go directly from Vienna Airport to Wien Hauptbahnhof in around 15 minutes, usually twice an hour. The U1 underground connects the main station with central Vienna. The official Railjet information lists an adult airport-to-city ticket at €5.50. REX7 regional express trains also serve Hauptbahnhof during the works, taking around 20 minutes. Choose whichever suitable departure comes next, especially if your hotel or onward train is near the main station.
CAT by bus: direct to Wien Mitte, but no train
The CAT name remains, but its current service is a non-stop coach to Wien Mitte/Landstraße. The tourist board’s CAT guide gives a 21-minute journey and departures roughly every 12 minutes between 07:00 and 19:00, less frequently outside those hours. At the airport, board outside Arrivals Terminal 3; the city stop is at Marxergasse 1b. Wien Mitte connects with U3 and U4. An adult single costs €14.90. City check-in luggage drop at Wien Mitte is suspended during the works.
What happened to the S7?
S7 trains still serve the airport but terminate at St. Marx, outside the centre. From there, tram 71 runs towards Karlsplatz, tram 18 towards Hauptbahnhof, and bus 74A towards Landstraße. The official S7 and REX7 advice confirms this temporary route. S7 can make sense if your hotel is near St. Marx; otherwise, factor in the extra change, particularly with heavy luggage or children.
Vienna Airport Bus: useful direct city stops
The separate Vienna Airport Bus network offers direct routes to several districts. According to its official route and fare guide, line 2 goes to Morzinplatz/Schwedenplatz in about 22 minutes, line 4 to Karlsplatz in 26 minutes, and line 5 to Praterstern in 28 minutes. Line 1 serves Hauptbahnhof and Westbahnhof. The adult single is €11. One direct bus may be easier than a faster train followed by two changes.
Tickets: do not mistake a city pass for an airport ticket
For ordinary airport-to-city rail travel, the published adult fare is €5.50: €2.30 covers the airport-to-city-boundary section and €3.20 covers Vienna. A city-only ticket does not automatically cover the airport. Holders of qualifying city multi-day tickets or the standard Vienna City Card generally need the €2.30 extension on regional rail. The Vienna tourism FAQ explains that an Airport Transfer add-on can cover selected airport services. CAT and airport buses have separate tickets. Prices checked 25 October 2026; verify before travelling.
At the airport: keep the transfers simple
After collecting luggage, follow the railway signs for ÖBB Railjet, REX7 or S7; the airport platforms are a short walk from the terminals and have step-free access. CAT replacement coaches instead depart from outside Arrivals Terminal 3. Vienna Airport Bus is a different operator, so check the destination before joining a queue. Buy the correct ticket for your service before boarding; a CAT ticket is not a standard ÖBB fare. For your return flight, check the journey in the opposite direction. A route that drops you beside your hotel may not be the easiest way back early in the morning.
Choose by your hotel’s address, not a headline time
Enter your hotel or final underground stop into a current route planner. Add time for bags, immigration, walking to the station and a possible wait. Check the first and last departures if your flight is very early or late; operators run different schedules. If step-free access matters, check your entire interchange, not just the airport platform.
