There are 6 airports in Austria with scheduled flights. The most important international airport is Vienna which has connection to all major airports of the world. Other international airports include Graz, Innsbruck, Klagenfurt, Linz, and Salzburg which provide domestic flights as well as connections to some European countries. Those airports are particularly popular with cheap airlines. For travelling to the western states it is recommended to use the very close Munich airport.
Austria has plenty of connections with all its neighbours daily. Every neighbouring country (even Lichtenstein) has trains at least hourly. Many (Czech Republic, Hungary, Germany, Slovakia, Switzerland), even more frequently. The ÖBB (Austrian Railways) operate high-speed ICE and RailJet trains from cities like Zurich, Munich,Frankfurt, Passau, and Budapest. Eurocity trains are the next fastest trains available as well as the trains connecting the bigger Austrian cities called Intercity. Regional trains called EURegio and simply Regionalzug are also available from all 8 of Austria's neighbours.

Eurolines Austria has bus schedules from Austria to all major European countries and back. If you make use of special offers and/or book in advance, travelling by plane or train is normally cheaper than by bus. However, the bus may be the cheapest option if you want to travel at short notice or if you have large amounts of luggage. Bus travel is especially interesting for those coming from the East as there are many busses into Vienna.
Austria and all its neighbouring countries, except Liechtenstein are Schengen members so in theory there are no border controls. For using the Autobahnen or Schnellstrassen, a vignette, or tax sticker, must be purchased.

PUBLIC TRANSPORTATION IN AUSTRIA:
Trains & busses:
Trains are the best way to get around if you are visiting cities. Comfortable and moderately priced trains connect major cities and many towns; buses other towns and lakes. The two forms of transport are integrated and designed to complement each other, and intercity coaches (long distance buses) are hard to find in most of Austria.
Austrian trains are operated mostly by state-owned company ÖBB. The Raaberbahn (GySEV) provides some trains over Austrian-Hungarian border and there are some short private railways with tourist trains.
The ÖBB operates also buses (InterCityBus) on line Graz–Klagenfurt–Venice because the road between these cities is much shorter that railway.
