Shanghai Airlines flights
Shanghai Airlines has two hubs that are located at Shanghai Pudong International Airport and Shanghai Hongqiao International Airport
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.
