Cape Air flights
Cape Air is an American operator that first and foremost offers domestic connections, even if they also have some destinations outside the borders. The airline is headquartered at Cape Cod Gateway Airport , with additional hubs in for example Boston, Nantucket and San Juan. Cape Air isn’t a part of any global 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.
