- Engine problems lead to 8 planes being grounded: IndiGo
- 80 flights cancelled: reports; all passengers re-routed: IndiGo
- Problems in engines made by Pratt and Whitney
IndiGo and rival GoAir have been facing delays in receiving planes from Airbus due to ongoing problems with engines developed by Pratt and Whitney, owned by United Technologies.
IndiGo flies four in every 10 Indian passengers.
Earlier this month, IndiGo, said it received compensation from Pratt & Whitney as the manufacturer struggles to fix glitches in engines that power Airbus SE's new A320neo jets. Airline officials said they could not comment on the amount paid to them and expressed concern that the engine issues could take over a year to sort out.
India has the largest fleet of A320neos.
IndiGo, controlled by billionaires Rahul Bhatia and Rakesh Gangwal, ordered 430 of the A320neo jets, of which 22 have been delivered, according to news agency Bloomberg.
