The British low cost carrier Jet2 is the third largest operator in the UK, following EasyJet and British Airways. The airline has more than 65 destinations and offers flights to most parts of Europe. They have their headquarters at Leeds Bradford Airport, with operating bases in cities like Glasgow, Manchester and Alicante.
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.
