Emirates is one of the flag carriers of the United Arab Emirates and also the largest airline operator in the Middle East. The airline offers flights to all continents and has its main hub at Dubai International Airport. Unlike most other large, international airlines, Emirates has chosen not to be a part of any global 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.
