Austrian Airlines flights
Austrian Airlines, commonly known as just Austrian, is the flag carrier of Austria and a subsidiary of the Lufthansa Group. The airline has its main hub at Vienna International Airport, and if you travel with Austrian you can find flights to Europe, Asia and North America. The airline is also a member of the global airline alliance Star Alliance.
An airline hub is an airport where the airline has a heavy presence and normally some kind of headquarters. On the other hand, a focus city is a destination where the airline operates limited point-to-point routes. In these cities, the airline doesn’t necessarily need to have an office (even though this sometimes is the case). Many low-cost airlines don't use the definition 'hub' but instead define their main airports of operations as an operating base.
