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.

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!

Ticket price is competitive, flight time is punctual, aircraft cabin is clean, food is average. Can improve on serving system of meals on a A380 airbus. I had only 15 min to eat my meal. There are lots of people to serve & took a while for food to make it down to my row.

The boarding process was awful-the computers were down and there was no way to check in. Took extremely long, very chaotic and no guarantee our bags were even getting on the plane. I was also delayed and took away from any time i had to catch a connecting flight.

Charged extra amount for the baggage wait. Even it’s less than 23kgs. Those machines are showing wrong weight and they were charging money wantedly from everyone.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar, wake up and do it right by your customers, or they may not be your customers anymore.

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

Dirty and smelly lavatory and toilets in Wamos Air operated flights

It was great! Kept the time. Provided what was promised

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

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

On this flight...fine. The one from India to Abu Dahbi, awful.

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.

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

Was so disappointing. Business class with no TV, uncomfortable seats. Had much higher expectations.

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

Seat space was tight and uncomfortable. There was hardly any cushioning giving me a terrible tail bone ache. Getting and out was extremely cramped. We paid for seat choices and felt totally ripped off. Food was mediocre. By the time the servers served 2 or 3 rows they ran out of this or that option as we saw on the inbound trip also. This is infuriating. Entertainment choices were extremely limited for such a long haul. The screen froze on occasion and did not switch off when the on off button was pressed. When it did it came back on its own in 5 seconds. The airlines has gone downhill since last year.

I think if i find different options I’ll travel with it but not with air India they never loaded the luggage’s and they announce the luggage’s will be arriving on belt number 5 when all passengers reach to the belt we find they haven’t loaded the luggage’s

The flight was on time, the entire experience was very smooth. The Flight crew were incredibly professional and nice. Made us feel very comfortable

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
