Tianjin Airlines flights
The Chinese operator Tianjin has its main hub located at Tianjin Binhai International Airport. The airline also has secondary hubs at Haikou Meilan International Airport and Xi'an Xianyang International Airport. They offer domestic routes throughout the country, and are not 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.
