Singapore Airlines flights
Singapore Airlines has its main hub located at Singapore Changi Airport and is the flag carrier of the country. The airline is a part of the largest airline alliance in the world, Star Alliance. They offer flights to most parts of the world, and have a total of more than 70 destinations worldwide.
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.
