IndiGo flights
IndiGo is the largest airline in India, both when it comes to passengers carried and fleet size. This low cost air carrier provides flights to more than 100 destinations, where most of them are domestic. IndiGo’s primary hub is found in Delhi. Like most low cost operators, IndiGo is not a part of any major global 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.
