While the Melbourne-Delhi flight AI-301 had clogged toilets in the Boeing 787 Dreamliner and had to be grounded at the Australian city earlier today, the other aircraft of the same make, operating flight AI-347 developed technical trouble at Singapore and reached Chennai this evening, instead of its scheduled arrival time of 1050 hours, airline sources said.
Many passengers of the Melbourne flight were given hotel accommodation, while some others were put on alternate flights after the cancellation, they said.
The recurrent problems with the Dreamliners is understood to have figured in the one-on-on meeting Prime Minister Narendra Modi had with Boeing CEO W James McNerney on September 29 in Washington.
Air India Chairman Rohit Nandan was also in Washington during Modi's meeting, after which McNerney told reporters that Boeing wanted to "accelerate engagement with India".
