IndiGo took delivery of its first Airbus A321neo on 28 December, marking the first of the variant to be operated in India.
The aircraft, registered VT-IUA, is owned and managed by the Indian low-cost carrier, Flight Fleets Analyzer shows.
The aircraft features 232 seats in an all-economy layout, compared to 180 seats on its A320neos. Like IndiGo's A320neos, the A321neo is powered by Pratt & Whitney PW1100G engines.
The addition of the A321neo to its fleet is expected to give IndiGo more options to pursue its long-haul aims. Earlier this month, the airline's interim chief executive Rahul Bhatia confirmed plans to start services to Istanbul after sealing its first codeshare, a pact with Turkish Airlines.
IndiGo has a backlog for 150 A321neos.
