Gurgaon - The Indian low-cost operator IndiGo has converted an order of 125 Airbus A320neo to A321neo.

Having already ordered for 405 A320neo (including 56 delivered) and 25 A321neo in LR version, the Indian specialist of cheap flight modified its order book. The carrier now expects 150 A321neo alongside 280 A320neo. The first A321neo will be delivered in November.

Neither IndiGo nor Airbus commented on this conversion. The local news portal Times of India citing two possible reasons: A320neo delivery delays (only one delivered in October) due to problems with Pratt & Whitney engines, and expanding the future international network of the airline - in particular the Gulf region, London Gatwick and some other airports in France, Germany, Belgium and Switzerland.

In addition to twelve ATR 72-600 out of 60 ordered, the IndiGo fleet is exclusively composed of the single-aisle aircraft of the European manufacturer with 126 Airbus A320 in service. IndiGo is one of the biggest customers of Airbus with 430 jets on order.

IndiGo had previously announced it plans to include to its fleet six aircraft per month from Airbus (A320neo) and ATR (ATR72-600).

Last March, the Indian budget flight specialist also expressed interest in ordering fifty A330neo which now seems delayed or abandoned. IndiGo, the largest domestic airline of India, holds a 40.3% share of the Indian domestic market.
