Key Takeaways
- Vienna dominates Austria’s skies. Vienna (VIE) serves around 163 regularly-served nonstop destinations — roughly four to five times the next airport — and is Austria’s only intercontinental gateway and the home base of flag carrier Austrian Airlines.
- Only Vienna flies nonstop to the US. Vienna is the single Austrian airport with scheduled nonstop service to the United States — New York/Newark, Chicago, Washington and Los Angeles — flown by Austrian Airlines and US partners. From anywhere else in Austria, a US trip means connecting.
- The rest are regional and leisure airports. Salzburg, Innsbruck, Graz, Linz and Klagenfurt are short- and medium-haul airports, busiest in the Alpine ski season and the summer holidays, with heavy charter and low-cost traffic to the Mediterranean and Turkey.
- Innsbruck is one of Europe’s trickiest approaches. Hemmed in by the Alps, Innsbruck is a winter-sports gateway famous for its demanding, mountain-ringed approach — a magnet for ski charters from the UK and the Netherlands.
- Vienna isn’t Austria’s only option. Bratislava, just 55 km east in Slovakia, doubles as Vienna’s budget airport, while travellers in western Austria often drive to Munich or Zurich for long-haul flights.
Austria packs a lot of mountains, music and history into a country of about nine million people — but its commercial-aviation map is surprisingly concentrated. Just six airports carry scheduled passenger service, and one of them handles the overwhelming majority of the traffic. The rest are compact regional gateways that come alive in the Alpine ski season and the Mediterranean summer.
That one airport is Vienna International (VIE), Austria’s only true hub and its single intercontinental gateway, home to flag carrier Austrian Airlines — part of the Lufthansa Group and a member of Star Alliance. After Vienna come Salzburg and Innsbruck in the west, then Graz, Linz and Klagenfurt. The map and table below rank Austria’s airports by the number of destinations they serve with regular flights, drawing on live AirportRoutes route data.
Which Austrian airports have direct flights to the US?
Just one. Vienna International is the only airport in Austria with scheduled nonstop service to the United States, reaching New York/Newark, Chicago, Washington and Los Angeles. The flights are operated mainly by Austrian Airlines, the country’s Star Alliance flag carrier, alongside US partners — with the route map shifting a little by season.
Everywhere else in Austria, a trip to the US means connecting — typically through Vienna itself, or via a larger European or Lufthansa-group hub such as Frankfurt, Munich or Zurich. Travellers in the west of the country (around Salzburg, Innsbruck and Vorarlberg) frequently drive to Munich or Zurich, both within easy reach, for their long-haul departures.

A closer look at Austria’s airports
✈️ Vienna International (VIE)
Vienna International Airport, in Schwechat about 18 km southeast of the city centre, is Austria’s largest and busiest airport by a vast margin and its only intercontinental gateway. It is the home hub of Austrian Airlines — the Star Alliance flag carrier within the Lufthansa Group — and a major base for low-cost carriers Ryanair and Wizz Air.
VIE reaches roughly 163 regularly-served nonstop destinations, including more than 60 intercontinental routes — by far the widest network in the country. Frequent links include Frankfurt, Munich, Istanbul, Berlin, Paris, Barcelona, Amsterdam and Zurich, alongside long-haul flights to North America, the Middle East and Asia.
Main airlines: Austrian Airlines, Ryanair, Wizz Air, Lufthansa, Eurowings and airBaltic, plus a wide range of international carriers. See VIE’s full route map on AirportRoutes →
✈️ Salzburg (SZG)
Salzburg Airport (officially named after Wolfgang Amadeus Mozart), only a couple of kilometres from the historic centre, is Austria’s second-busiest airport — though a fraction of Vienna’s size. It is best known as a winter gateway, swelling with ski charters bound for the Alps and weekend visitors to Mozart’s birthplace and the summer festival.
SZG serves about 36 regularly-served destinations, weighted toward German-speaking Europe and seasonal leisure markets. Frequent links include Frankfurt, Istanbul, London (Stansted and Gatwick) and Amsterdam, with a heavy winter surge of charter flying.
Main airlines: Ryanair, easyJet, Eurowings and TUI Airways, alongside seasonal charter operators. See SZG’s full route map on AirportRoutes →
✈️ Innsbruck (INN)
Innsbruck Airport sits in the Inn Valley, ringed by the Alps, and is one of Europe’s most spectacular — and technically demanding — airports to fly into. The mountain-hemmed approach requires special crew training, and the airport is a magnet for winter ski charters from the UK and the Netherlands.
INN reaches around 18 regularly-served destinations. The network is dominated by Vienna and seasonal links to London (Gatwick and Heathrow), Amsterdam, Rotterdam, Eindhoven, Hamburg and Manchester — a clear reflection of its role as a ski-season gateway for northern Europe.
Main airlines: easyJet, Transavia, British Airways, Jet2 and Austrian Airlines, with extra charter flying in winter. See INN’s full route map on AirportRoutes →
✈️ Graz (GRZ)
Graz Airport serves Austria’s second-largest city and the surrounding region of Styria, in the country’s southeast. It is primarily a business and connecting airport, feeding travellers into the big Lufthansa-group hubs.
GRZ serves about 11 regularly-served destinations, led by the German hubs of Frankfurt, Munich and Düsseldorf plus Vienna and Zurich, with seasonal leisure routes to Turkey (Istanbul and Antalya).
Main airlines: Eurowings, Lufthansa and Austrian Airlines, with Pegasus and SunExpress on the Turkish routes. See GRZ’s full route map on AirportRoutes →
✈️ Linz (LNZ)
Linz Airport (officially the Blue Danube Airport, at Hörsching west of the city) serves Linz, the capital of Upper Austria and a major industrial city on the Danube. The smallest-but-one of Austria’s scheduled airports, it leans heavily on leisure and low-cost traffic.
LNZ serves around 6 regularly-served destinations, a mix of sun-and-city routes such as Alicante, Istanbul, London (Stansted), Bari and Antalya, plus the holiday favourite Hurghada in Egypt.
Main airlines: Ryanair and Turkish Airlines, with Corendon and other charter operators on the seasonal leisure routes. See LNZ’s full route map on AirportRoutes →
✈️ Klagenfurt (KLU)
Klagenfurt Airport serves the southern region of Carinthia and the lake district around the Wörthersee, a popular summer destination close to the Italian and Slovenian borders. It is Austria’s smallest scheduled airport by route count.
KLU serves about 5 regularly-served destinations, anchored by the domestic link to Vienna and supplemented by low-cost and seasonal routes to London (Stansted), Cologne/Bonn, Hamburg and the Spanish leisure markets of Alicante and Palma de Mallorca.
Main airlines: Austrian Airlines, Ryanair and Eurowings. See KLU’s full route map on AirportRoutes →
What about Bratislava, Munich and Zurich?
Three foreign airports do a quiet but significant amount of Austria’s flying. Bratislava Airport (BTS), in Slovakia, sits just 55 km east of Vienna — the two capitals are the closest pair in Europe — and works as a low-cost satellite for the Vienna region, with Ryanair and Wizz Air links that often undercut fares from VIE.
In the west, where the Alps put Vienna a long train ride away, many travellers look across the border for long-haul flights. Munich Airport is the natural choice for Salzburg, Innsbruck and the Salzkammergut, while Zurich serves Vorarlberg and the far west. Both are major intercontinental hubs within a two- to three-hour drive, and frequently win the western Austrian catchment for flights to the US and Asia.
Airport rankings, nonstop-destination counts, served cities, airline lists and US connections are drawn from live AirportRoutes route data (observed AeroAPI flight data — a sample, not a complete published schedule; we use the regularly-served figure, which filters one-off observations).
