Iberia Express flights
Low cost carrier Iberia Express is owned by the Spanish airline Iberia. Iberia Express operates out of Barajas Airport in Madrid. The airline offers flights to several parts of Europe, and is an affiliate member of the international airline alliance Oneworld.
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.
