American Airlines flights
Being the largest airline in the world, American Airlines holds a bigger fleet and carries more passengers than any other operator globally. This US-based airline has ten major hubs, like for example Dallas, Chicago, New York and Los Angeles. American Airlines is a major player both nationally and internationally, with more than 350 destinations. They are also a part of the 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.
