EasyJet is a low cost carrier with its base in the United Kingdom. The headquarters is located in London Luton Airport, even though the largest base is to be found at Gatwick. The airline offers both domestic and international connections – in total EasyJet operates flights to more than 30 countries. Since EasyJet is a budget airline, they are not part of any major 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.
