Avianca is a Columbian low cost carrier and the flag carrier of the country. Around 80 percent of Avianca’s operations are South American connections, even if they also offer some destinations in North America and Europe. The airline's main hub is located at El Dorado International Airport in Bogotá, and they are a part of the global alliance Star 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.
