IndiGo put two of its Airbus A320 Neo aircraft back into service on Tuesday and expects a third NEO aircraft to be back in the air by late Tuesday night, the airline sources said.

Earlier this month, the Directorate-General of Civil Aviation (DGCA) had grounded the airline’s 11 Airbus A320 Neos due to issues with Pratt and Whitney engines which powered the aircraft. Three GoAir NEO aircraft too had been grounded for the same reasons.

Meanwhile, Aditya Ghosh, President and Whole-Time Director, IndiGo, said the airline is actively engaged with the engine manufacturer on getting all its aircraft back in the skies in the coming months. “We did not have to cancel more than 35 to 45 daily flights on any day, which is around only 3 per cent of our schedule. We are able to offer a wide and deep schedule of flights to our customers. Therefore, we have been able to quickly accommodate our customers on alternate flights and minimise any operational disruptions. In our business, safety is our top priority,” Ghosh said.

The airline’s President said IndiGo expects to further reduce daily flight cancellations in the coming week.

IndiGo operates over 1,000 flights a day while GoAir operates over 250 daily flights.

The grounding of the 11 aircraft came after three cases of inflight engine shutdown.
