Food was great. More vegetarian options on menu would be great!

Food was great. More vegetarian options on menu would be great!

The main issue was that the flight from trivandrum to Dubai was delayed which resulted in arriving late in Dubai. Coincidentally the flight leaving out of Dubai to jfk was also delayed for different reason. Despite we reached the gate ( through wheel chair assistance) along with 10 other passengers we were not let in. The gate was open and yet was refrained from entering. We were then requested to flight the next morning. Meal vouchers were provided but the hotel reservations were not made and took a lot longer to receive that. If Emirates knew about the delay and was certain the passengers will not be able to board the next flight shouldn't they have prepared these ahead of time?

I would have liked less packaged snacky stuff, more fruit. The crew was great.

Had to do shuttle bus both times during the transfer. It was waaay longer than acceptable. These 777s need a refurbishment really badly. Emirates and Dubai Airport used to be top notch. Now overcrowded and outdated.

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Delayed and missed connecting flight. But Emirates took care until next day flight. Thank you

They should resume the fast track for business / first class passengers

no problem with Emirates it was the underpricer subcontractor Who was ridiculous

Good flight overall. Good options of food on NY-Dubai-Mumbai leg. Not that good reversing back. The flight crew is courteous and professional as always. The seating was much more comfortable going into Mumbai than coming back. Cheers!

It was little disheartening and disappointing. Although flight staff did a good job. But customer service didn’t do anything to resolve my issue.

I wish the leg room was better for Economy especially for the outbound flights to India . The outbound flight to US and Qatar was good

The flight was operated by IndiGo and not Qatar, which is a budget airline from India. Nevertheless, the flight was uneventful.

Indigo airlines is terrible. Staff is awful and so disorganized. They are so rude and unhelpful. I will never travel on Indigo airlines again!!!!!

They didn't board by zones and it was a free for all. The 16 hour flight was the most excruciating experience of my life and the seats were TINY... with no leg space and my feet were swollen immediately. The food was so bad it was inedible.

Qatar Airways did a very good job. Flights were slightly delayed with boarding but pilots made up time by arrival. The food was OK, no better or worse than other airlines. Although it would be nice to have three meals during 16 hours flight instead of two.

The space was tight, hardly any leg room and the crew surprisingly were busy and did not take the time to attend to passengers, felt rushed. There was a delay for check in since the systems were down the airport staffs were accommodating

I was denied lounge facility at airport. Explanation was not satisfactory.

Moved seats, didn't accommodate requests to change seats even though other seats were available.

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

Nice crew , clean cabin , food was delayed due to problem with the quantity .

I booked and paid for a Business Class seat for myself and my wife. 4 hours before the flight i get a call saying the plane they sent doesn't have the correct layout to accommodate all the business class seats they sold me 3 months earlier at a premium of $1500 a ticket. So they have to bump me from Business to Economy and will give me a $400 credit (total of $800 for both seats) that I could turn in at Abu Dahbi for $400 in US cash. They then promised a row that we could have to ourselves and the arm rests would go up so we could spread out for each of us. My wife was taken care of but I was put in the exit row with the flight attendents set as part of the three...and the arm rest did not go up. When we got to Abu Dahbi, they would not exchange our credit for cash as promised. Very disappointed they took my money 3 months ago and refused to reimburse for the change in seats or follow the promises made.

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

It was an old plane with seats not comfortable and with little space for the legs. I must say that the previous flight I had was amazing on a very comfortable new plane

It’s a business class ticket but they didn’t give a lounge access

The flight from Abu Dabhi to Bangalore was terrible. The plane was an order model with no onboard entertainment. The beverage selection were very limited.

More leg space than other flights, but felt like *maybe* narrower seats?

Will never book any flight from Kayak and will never travel ithad airline

Same problem place in the middle so small Im 1,85 m so not good 👍

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

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

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

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

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.

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

The boarding experience was very organized and easy to follow. The flight was pleasant and the food provided was also very good. Both Delhi and Mumbai airport have metro connections which make getting around much easier.

Food, choice of menu and quantity were poor. Crew services were even poorer, not attending call bittons

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

There’s no comparison for new avatar of air India. Long live Air India. Amazing hospitality and ultra soft polite charming crew
