The Malaysian airline AirAsia has its main base and headquarters located at Kuala Lumpur International Airport. The airline offers connections exclusively in Asia and has more than 150 destinations. They have several operating hubs, like for example Senai International Airport and Kuching International Airport. AirAsia isn’t part of any major global airline 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.
