seats were not comfortable, entertainment was not working and food could be much better, given the airline calls itself full service and india's flag carrier.

seats were not comfortable, entertainment was not working and food could be much better, given the airline calls itself full service and india's flag carrier.

The planes did not have charging jacks for phones or lap tops and there are no monitors for movies. On the flight from Delhi to Hyderabad I was the last person in First asked for a meal choice and only one meal was available so I had no choice.

Entertainment systems did not work at all And the seats are the worse on this 787-8 aircraft. Normally I get good sleep on long flights but this time I only slept 2 hours out of the 8+.

Never ever travel with Air India is a very conscious promise made to myself. Poor customer service , irresponsible staff, pathetic operations and bad planes. Overall -0/10. Planes had mosquitoes in it.. i am still thinking what international standards of hygiene are they even following????. Operations team has no quality standards. They can route you anywhere on any plane inspite of a confirmed ticket and a web checkin… without your consent. Go for AirIndia if you love challenges and roller coasters and safety, time and hygiene is never your priority.

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

Flight has no entertainment. Crew doesn't care atall. Horrible service and never going to take Air india and will spread their Horrible service.

Undisputed leader in sky for Indians. Very good crew right from ground to mid sky. Very sumptuous meals twice

Worst staff from Vienna. one of the server was very rude and annoying as she thinks she owns the airlines

Uneventful trip. Good flight crew. Food could have been better and a bit more of it. Cabin cleanliness was ok.

Mumbai to New York was not comfortable as I was given different sits in hat what I paid for
