The Dutch airline KLM is one of the oldest operators on the market, with over 100 years in the business. KLM har its main hub at Schiphol Airport in Amsterdam and is also the flag carrier of the Netherlands. With KLM you can reach most parts of the world, even if the majority of their flights are found in Europe. The airline is a part 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.
