Chengdu Airlines flights
The Chinese airline Chengdu Airlines is a subsidiary of Sichuan Airlines, and offers mainly domestic flights. The airline has its headquarters located at Chengdu Shuangliu International Airport. They are not a part of either of the large global airline alliances.
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.
