Frontier Airlines flights
The American ultra low cost carrier Frontier Airlines offers mainly domestic connections, with over 100 destinations in the US. The airline has twelve focus cities in total, where some of them are Atlanta, Denver, Las Vegas and Miami. Frontier Airlines isn’t a part of any global airline alliance, but has codeshare agreements with several other operators.
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.
