Qantas is the flag carrier of Australia and the largest airline in the country both when it comes to international flights, international destinations and fleet size. They have three major hubs – Sydney, Melbourne and Brisbane. Most of their connections are found in Oceania, and they are also a part of the worldwide alliance Oneworld.
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.
