Spring Airlines flights
The Chinese low cost carrier Spring Airlines have about 100 destinations, where the majority are domestic connections. Spring Airlines has two larger hubs – Shanghai Hongqiao International Airport and Shanghai Pudong International Airport. Like most other low cost airlines, Spring Airlines isn’t a 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.
