The Mexican airline Aeromexico is the flag carrier of the country and has its base in Mexico City, where they also have one of their major hubs. The others are located in Guadalajara and Monterrey. Aeromexico is first and foremost an active operator in North and South America, while they also offer connections to some parts of Europe. They are also a founding member of the global airline alliance SkyTeam.
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.
