Jeju Air flights
Jeju Air is the first, and largest, low cost airline from South Korea. The airline has three main hubs that are located at Jeju International Airport, Gimpo International Airport and Incheon International Airport. Jeju Air has more than 40 destinations and connects most parts of the Asia-Pacific region. They have a codeshare agreement with Jetstar.
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.
