My wife with 5 month son were traveling. No proper support was provided for luggage handling. Although it was requested in prior. My wife sole manage everything and was not as expected.

This was an old 320 without a screen or USB charging port even in the business class. The food could have been better.

a real good flying experince. Everything was excellent right from check-in to baggage collection at destination.

Food is tasting bad, and it is a fusion but not authentic.

Excellent experience and now my preferred airline. Even a fantastic meal with dessert in a 2 hour flight.

off late the crew and the air in the flight is becoming that of a budget airline not the earlier Vistara .

It wasn't clear from where to board flight international or domestic Airport

Information was not clear from where to check in international or domestic Airport at Ahmedabad.

The deplaning experience was bad, since they did not get the aerobridge at Madras on arrival and the bus felt like a local train during office hour rush

i bought a biz class fare but a few days before vistara always changes my biz class flight to economy .. happened to me 4 times .. seated could be wider .. boarding could be more organized .. crew did their best but not enough resources all in all very poor experience

Communication was terrible. Flight was delayed for 4-5 hours in DC (on the front end, and also after we boarded, we had to get off - some issue with fueling the old plane correctly). There was little to no information on timing or what was happening. Once we reach Delhi airspace, apparently there was weather that caused us not to land - we were actually near the ground, saw the run way, and lifted back up to the sky after being sooo close. Then we circled for about 30 minutes, and they decided to go to Jaipur to land until the weather cleared and to refuel. Again, once we landed in Jaipur (wrong city), there was little to no information on timing or what was happening. Then we heard that the crew was reaching their 24 hours. We sat on the place, on the tarmac for another 3 HOURS, with no food and not enough water for everyone on the flight. Then, they kicked us off the plane with no plan, in the wrong city. We went thru customs, got our bags (thank goodness), and had to ask a bunch of staff what was happening and what to do. Eventually, their soltuion was to bus people back to Delhi (like 6 hours we were told) but not everyone would fit on the bus, and unknown timing on when it would leave. At this point it was 9PM (we were scheduled to arrive in Delhi at 11AM...). My husband and I decided to risk it and take a cab that we had to pay ourselves (about $200 US dollars) to get to Delhi (about 5 hour drive). We both had terrible trips back to the US as well - almost missed connecting flight, forced to pay for carry-on luggage (a small back pack!) and duty-free goods by the Air India staff last minute. Just terrible experience all around. Never again with AI! The ONLY good thing was the air hostesses were kind and patient - example: they made sure people with food allergies got their correct. However, the TV's did not work so I'm glad we brought our own entertainment.

Need to update the staff of the airport. They tell luggage weight according to they want.

The Air India lounge in Delhi , was very disappointing! The food was of poor quality and options were limited especially for vegetarians!! Beverages were fine. The in flight crew was excellent! . They helped me with my seat controls - the controls did not work without a hassle or assistance!! A very poor showing for a Business cabin!!! Post flight , the wheel chair passengers ( including Me) were “ shepherded and left waiting twice (an hour or more) before taking us to immigration! I chose to Fly Air India because I want. to patronize our National carrier with the hope that the experience will improve!!! Regrettably, I will have to look at other options for my next trip to India

Mediocre staff, crappy food selections and no entertainment for a 14 hour flight. The only good thing was that it was a direct flight.

Entertainment system was not working and was told I would get a voucher and have not got one. No toiletries were available not even a toothbrush false sweet talk by ground staff

Not comfortable for sitting. Sits are too close to each other and it’s too hard for butt..you need to improve your entertainment section like tv programming, Movies, it’s so hard to kill 15 hrs in long flights .you don’t serve good food like other competitive airlines thats my opinion

Worst International flight I ever had in my whole life time. Boarding is the worst of all and flight experience was also not good. Screens were not working, seats were not comfortable and lot more.

Comfortable seats, on time departures and arrival, and helping staff

Very very impressed with the proactive care and alertness with which ABHISHEK Chowdhary took care of us. Quietl,dignified , very alert, and meticulous. Very impressed. Also with SUNiL Kumar who was there for us in a very helpful way. SHERLY ALEX On Flight 119, BOM TO JFK CUSTOMER ON SEAT 21C, 21ST March 2024
