Batik Air flights
The Indonesian airline Batik Air commenced its operations in 2013 and has its main base at Soekarno Hatta International Airport in Jakarta. They also have a hub at Sultan Hasanuddin International Airport. In total the airline offers about 50 destinations. Batik Air isn’t a part of any global alliance, but has a codeshare agreement with 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.
