Very old aircraft. Business class seats don’t work right. No way to get out my tray table. Crew didn’t seem surprised about the aircraft and didn’t have any real answers. Old 777 seems to not have been updated ever.

Very old aircraft. Business class seats don’t work right. No way to get out my tray table. Crew didn’t seem surprised about the aircraft and didn’t have any real answers. Old 777 seems to not have been updated ever.

They rescheduled flight..no customer care to even reach or accommodate

Bad weather in Amritsar cancelled the flight while we were at the gate in Delhi but the ground crew took good care of us and exceeded our expectations. Once on the plane, we enjoyed the best experience we’ve had on any flight in years. Their customer support was also impressively quick to answer and immediately helpful.

Unnecessary delays & Gate changes, so much inconvenience after 15-16 hours flight

Needs lots of improvement starting from crew/staff attitude, cleanliness, better quality food & in flight amenities.

Old and filthy aircraft Boarding was free for all with no zones

Very old and ill maintained flights. Seats didn’t have proper cushioning. The entertainment system was a joke. That’s the least one can expect from a 19 hour long flight.

Flight was delayed in phases from 84ppm to 2am. And at 2am it was cancelled. Only refund option provided and no stay was provided. Poor communication throughout and shameless behaviour from the airline with no regard for seniors citizens and those travelling with children.

Poor entertainment. Charging station was broken, not clean washrooms, 6hrs delay , no apologies given

Very bad experience luggage never made to destination no help form airlines staff aircraft was old crappy forts staff service bad airlines staff
