Flydubai is a low cost carrier that has its main hub at Dubai International Airport, with Al Maktoum International Airport as a focus city. The airline offers flights to both Europe, Asia and Africa, and in total Flydubai has more than 100 destinations. They are not a part of either of the major worldwide airline alliances, but offer a codeshare agreement with Emirates.
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.
