IndiGo Airlines (6E, Delhi Int'l) is considering converting part of its order with Airbus (AIB, Toulouse Blagnac) for 405 A320neo to A321neo (LR)s, the Financial Express has reported. The conversion will most likely cover 20-25 aircraft slated for delivery during Fiscal Year 2018-19, according to inside sources.

The new aircraft could be used for new medium- and long-haul services planned by the carrier. IndiGo recently applied for route authorities to a number of European destinations which would supplement its existing international regional network to the Gulf region, South East Asia, Nepal, and Sri Lanka.

The first A321neo(LR), the largest member of the A320neo Family, completed its maiden test flight on January 31, 2018.

The Indian LCC is also mulling an order for A350s, which would become the first wide-body aircraft in the carrier's fleet. However, as previously reported, Indigo's twin-aisle fleet plans depend on the outcome of the Air India privatisation process. If IndiGo succeeds in acquiring the Indian flag carrier, it may base its own long-haul expansion on Air India's fleet instead of acquiring new equipment.

According to the ch-aviation fleets module, the Indian LCC currently operates 126 A320-200s, thirty-two A320neos, and three ATR72-600s. IndiGo also has a further 373 A320neos and twenty-five A321neos on order with Airbus.
