Aer Lingus flights
Aer Lingus is an Irish airline with its main hub at the airport of Dublin. The airline is the flag carrier of Ireland and offers flights to almost 100 destinations both in Europe and in the US. They also have three focus cities – New York, London and Manchester. Aer Lingus isn’t a part of any international alliance, but codeshares with American Airlines.
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.
