Air China flights
Air China is the flag carrier of the country, and also one of the biggest Chinese operators. Most of the connections offered by Air China are between different Asian cities. There are three main hubs, one in Chengdu and two in Beijing (PEK and PKX). In 2007 Air China joined Star Alliance, which is the biggest international 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.
