IndiGo is a low-cost airline and the largest airline in India. Its fleet is constantly expanding and renewing, and IndiGo's aircraft are among the youngest and newest.

IndiGo normally operates between 400 and 500 aircraft, mostly Airbus A320/321 or ATR72 types. It also leases Boeing 777-300 aircraft from other airlines for over 500 passengers, the most passengers on this type of aircraft of any airline in the world.

Its main domain is its very dense and frequent domestic route network across India.

But IndiGo is also steadily expanding abroad, flying to many countries in South and Southeast Asia, the Arabian Peninsula and Turkey.

There are plans to launch long-haul routes to Europe, for example.
