Shenzhen Airlines flights
The Chinese airline Shenzhen Airlines offers mostly domestic flights. As you can guess from the name of the airline, this operator has its main hub as well as its headquarters located in Shenzhen. Shenzhen Airlines has been a member of the world’s largest airline alliance, Star Alliance, since 2012.
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.
