The Australian low cost carrier Jetstar offers about 40 destinations, most of them located in Australia and the rest of Oceania. The airline has eight operating bases, for example in Melbourne, Adelaide and Sydney. Jetstar isn’t a member of any global alliance, but codeshares with operators such as American Airlines and Emirates.
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.
