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

Premium economy was worth it-comfort was definitely better than economy class. The seats were more comfortable, blankets and pillows thicker

Very poor boarding experience with these remote gates and buses. Also these 777s bardy need a remodeling. Entertainment is a bit laggy. Food and crew is still among the better, but they seriously have to do something with these remote gates.

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.

No kids provided. Instead we were told to have contacted the airline that we have kids and require kids meals. We were not the only ones who inquired about kids meals. It’s odd. Emirates and other airlines give kids meals as standard and before the adult food comes out. The rice in our meals was gluggy and under cooked. The chicken was also raw. Sadly not the best experience with Finn Air. The hostesses tried to compensate with the snacks and drinks but missed the mark by a long way. Especially when paying Emirates/Qantas prices

Sadly I couldn't get the food I requested as it was out. Also, if you don't want to be woken up make sure the crew knows it. My wife was woken on every service.

I lost my lock from my luggage, I don’t know someone took something from my bag.

We travelled in economy, were very satisfied with the comfort and keg space of the seats. Food was great compared to other airlines, the crew were very helpful and friendly. Since i was travelling with kids, i needed assistance multiple of times. Will be definitely taking long flights with Emirates from now on.

Emirates First Class is always a treat with Caviar and service is always personalised.

Very pleasant.The crews are very nice.Food were excellent.

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.

Seated in row 6 you are separated from business class close to the toilets. The is a high panel in front that obscures forward viewing, coupled with no window view. Service is limited as the area is not in view of the attendants. It is closer in proximity to economy than business class.

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight overall was good. The attendants did a good job except that 1 female had too much fragrance on. The other things that made the flight unpleasant were out of the airlines control.

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

The seats were uncomfortable. The service was poor. We bought internet for my family and myself and it didn’t work. The charger for our phone didn’t work. The service seemed like they were tired and exhausted and seemed a bit upset. It was not a good flight. Our flight from miami to Qatar was great but from Qatar to Tokyo was simply awful

I purchased Qatar airways after seeing ads about its service. To my surprise Qatar is marketing gimmick and horrible airlines which I don’t recommend to anyone Flight was dirty including flight from Miami to Doha And Doha airport restrooms are dirty On top of this they use this pathetic cheap indigo From Doha to Hyderabad which I will never fly Also they lost one of my baggage in Indigo and still waiting to receive it. I will never travel Qatar and will never recommend

The food is not good and also if you ask crew to bring something they say ok I will bring but you will never get it. Please they should listen good to passengers

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

riding in first class, you don't expect every time you order your dinner or breakfast that the first thing the stewardess says is Let me see if we have any left. Also, the food selection was not great: 3 of 4 entrees had mushrooms and I dont eat mushrooms, the 4th item was 'let me see if we have any left' and this was within 30 mins of entering the flight! Same experience level, it didn't feel first class this round.

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 fantastic. The flight from Chicago to Abu Dahbi was fantastic. The crew, food and service were amazing. Everything was handled by the crew member assigned to us , Nicholas, was usually done before we asked for it. Highly recommend Etihad!

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

Very disappointing #1 - You have to pay extra to use the business lounge, or else you sit in the cold airport for 7 hours and fall sick #2 - Did an awful job with boarding, they turned on the "last call" notice on the monitor made the passengers come running to the gate, once the passengers came close the crew would tell them - hey we are not boarding yet, this included passengers with children also, this was happening all the time, it was pitiful to see #3 - Did not have the courtesy for the passengers in the business class, there is a reasons why people choose business class, because they need to get to work, that means sleep is very important for them, in the business class, the crew members would themselves cause so much noise by closing the door in a loud way, once the crew member does it then the other passengers are also doing it, #4 - the food did not smell good, #5 - The Abu Dhabi airport is small, so not a whole lot to do, especially when the layover is 7+ hours. #6 - Did not provide the slippers with pajamas, #7 - also the pajamas also I had to ask, only after asking it was provided. #8- Asked for an extra pillow because the pillow they provided was not tall enough, the crew member said there was no additional pillow and gave me something like a blanket, I tried my best to use that as a pillow, but my head kept on sliding and that messed up my sleep and did not get deep thorough sleep Overall the airlines did not have an understanding of how to care for the passengers, especially the business class ones. Overall it was a bad experience, I would much rather spend the money with Qatar airways, the experience with Qatar is so much better.

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

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 paid 44 $ for seat upgrade (22D) and my seat was stack in high position for all the 6 hours of flight. I don't recommend the upgrade. I am looking to get my upgrade payment back

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?

My baggage was not boarded and is still missing. I was only carring one piece of luggage and that is misplaced now I am stuck at mumbai without luggage. I had an onward journey from here

Bad sitting every flight not good experience with food either

It would be great if the flight attendants could inform people travelling with small children that at take off and landing the children should drink liquid or chew/swallow something so their ears don’t hurt. Also, Emirates serves the food to the children first. Really good idea. Best of all would be to put all children in the same area.

Changed to older plane with old set-up in Business class.

Requested food items were always finished but the available food was warm and tasted good Good entertainment options.

I am elderly and needed wheelchair assist. The ground crew assisting me with that part of my journey was rude, disrespectful and very hungry for money; the begging was distasteful and disrespect for females and the elderly was atrocious. Maybe they need to get a raise...I was out of small bills by time I reached home. As an american I am not use to the impoliteness. The ground crew make your wonderful airline appears poor in performance...a lot to be desired.

Amazing service on board in business class. The lounges are also great. The inflight entertainment could do with a larger selection and the food choices more but overall, very pleased.

As a big guy the seats are way too small for me. Would prefer more comfortable seats on these long haul flights.

the flight was cancelled and I was rebooked twice, once 26 hours later, then another 24 hours later. In total the flight was delayed for 40 hours. Never again will I use kayak or Turkish Airlines for my travel.

it was a terrible experience. after 4 hours at the gate the flight was cancelled. the airline offered to rebook the flight for 26 hours later. Our team was travelling for an international competition. They missed the competition because the airline delayed them for over 30 hours. We already left the airport but the next morning we received an email stating that we were rebooked for a flight which was another 24 hours later after the already rebooked flight. We bought a ticket on Kayak. The reservation was delivered with a logo Airfareassist. I used Kayak services for over 20 years and assumed that I was dealing with a legitimate organization. Once the flight was postponed for over 40 hours, I learned that Airfareassist is a 3rd party agency whom kayak routes business to without notifying me, the customer. While I was entitled for a full refund, which was confirmed by the airline, Airfareassist only offered a partial refund and kept the difference. Kayak has failed to do a due diligence on the 3rd parties they do business with. As a result I will never do business with kayak again and am filing a complaint with the BBB and the Secretary of Transportation. This is a pure fraud and its unacceptable.

It was great! Great value for the price I paid. Great crew and great food in business class
