I am going to be just factual, not bad mouthing nor complaining, but this was my experience. With 3 pieces of luggage, I was told the flight from Mumbai to Dubai was cancelled due to flood. This was told not by the airport board which still showed the regular time of departure, but general stuff at the airport. No Emirates stuff around to direct the transfer passengers of the cancelled flights. By the departure counters with crowds of people, one by one, angry, frustrated, urgent conversations were going on. No announcement were made, no postings being seen, just private conversations. I still have 5+ hours of layover, so I let more urgent people settled first. However, the fact that no communication of when, what and where I should go was very unsettling. Basically no time limit waiting means, no meal, no sleep, no step away, no planning, no change plan, no telling of the family what to do. Nobody was able to tell you anything but asked you to wait, no chair, no space, no facility to freshen up. That went on for 10+ (from 5) hour without warnings and accurate communications. Email received from Emirates asked me not to go to Dubai at all, or boarding at the time that was passed. In other words, communication were very untimely, after the fact. That created more confusion instead. After changing several of boarding time, we were given the gate # and a boarding pass. However, the boarding pass still have the original time of boarding, so again, not knowing walking 30 min in the airport to the gate would make you late or not, therefore, still dare not to eat a meal. The flight arriving to Dubai was uneventful and I gave a 4/5 rating. I just thought the layover at Dubai would just cut short from 8+ hours to 2+ hours. At Dubai airport, I saw people sleeping on cardboard, knowing, these people got stranded but they dared to sleep because they know when to board and I didn't. Or these kind of delay are just so normal that people know what to do to pass time. Then the worst service and crazy thing happened. The boarding time on board for LA and at gate A9 was clearly 8:50AM. At 8:40, surprised by not having any boarding activities, then one single staff showed up and said to a few passengers that the boarding would be delayed without a time frame. Since only a few people know, I asked another Emirates staff at another counter, who simply said basically non of his business. I was shocked with that indifferent attitude. Yet every boards I saw show the same boarding time. What kind of system failure was that to prepare delay situation! How confusing and unnecessary chaos and anger that provoke. That poor staff had to repeat himself so many times, answered questions that he had no power nor information to provide nor solved. One an only one stuff to show up for 10 min, leaving the counter non-staff with board showing 8:50AM boarding. This was purely irresponsible from top to bottom of the entire airline operation staff. What kind of leader in a service industry would allow this to happen to their customers. Without explanation, after changing 3 times the boarding times, again, means you should not go to eat a full meal, because, when you found a mob at the gate. People who were stranded for 2 days were afraid of not getting a seat with a full plane. That would not be happening if the airline provide adequate guidance to each person, instead of just having 4 staff yelling at the gate at the same time to "control" the crowd, threatening no boarding and delay boarding. Finally, I was on board, hungry and tired, not sleep for 36 hours. I was denied with a snack of fruit. By the time meal was served, it was an hour later. Half way of the trip, I felt sleep in fetus position and did not want to move, happy I finally could have some shut eyes time. However, when I got up to the bathroom, I felt very light headed. Having sleep deprived, constipated for 3 days, dehydrated, I knew it could happen since my blood pressure usually was low closed to 90/60. Any lower then that, I could have syncope. Sure enough, I was on the floor just 10 feet from my seat and 5 feet to the bathroom. However, nobody called for help. I asked for warm water and juice to hydrate, came only with cold and icy drinks which I wouldn't take. I asked for blankets, one was given. Yet my shivering, needs to cover my head and multiple requests did not hasten to take the two blankets that are at my seat 10 feet away. I waited 10 min for that. While 2-3 staff surrounded me, nobody did the vitals until after 15 min, just the spirometer only of which did not work due to my cold fingers. The first reading was 86 and oxygen was suggested. But another supervising personnel came, fussed over another reading, ignoring my comfort and needs. Seemingly the reading of spirometer was the priority. By then, no oxygen needed. I had this fainting experience before, and I knew how to help myself. However, I was not being listened to but to be told this and that. Finally, I got better and returned to seat. One kind flight attendant said she would check back with me in 15 min. She did not come back. I felt asleep in that fetus position again and this time I woke up with a bad cramp at my left leg. Yet I needed to go to bathroom, the cramp was too bad to walk. So I stepped back to seat. When I tried again the second time, the other front leg got cramp. This time I dare not move but massaged myself. For all these 5-10 min, I called for attention. Attendants passed me by because they were carried with heavy load of blankets and stuff. Nobody answered the light. Then came landing and off board. I was asked by two attendants how I felt. I smiled and said "fine".

The customer service was very poor. I didn’t get any accommodations for my cancelled flight. I was without any sleep for 36 hours.

My Experience was ok. But the gentleman next to me vaped the whole flight and the attendants did nothing, whether they were aware, I’m not sure.

Service needs to improve. Air hostess do not register flyers request and we need to keep on repeating our request to them on multiple occasions

Absolutely terrible delays for 3 hours changed seats after we paid an upgrade on both legs. It appears it’s up to us to request a refund after they down graded our seat. Never again !!

I was traveling business purposes and I only had one carry on and a personal computer back pack . My carry on was 8.5 kg little more than allowable. At jfk airport check in they did not let me carry it . I was little disappointed.

More leg room and comfortable seats at least for long flights

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

Me and 2 other rows were forgotten during food service. We waited over an hour before they finally served our food. Then only had what was left. They did apologize. Also, they locked the bathroom due to turbulence and my 4 year old had to pee himself because they wouldn’t unlock it for him.

Had the salad which tasted awfully spat it out but still got food poisoning 1 after running to toilet crew would not let me sit near toilets I was stuck in window seat

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

Good aorcraft 777 but Worst food ever Breakfast was a bû’with matonnaise… Staff was nice but invisible most of the flight

Everything went smoothly with Air France. There was a delay in departure which seemed to relate to the immigration services being short staffed.

No bording was given for next trip on same carrier, food was very moderate.

Lost luggage, 2 bags were badly damaged and one of the bags came open.

The line at boarding was not well organized and managed

Crew was professional. Boarding has few seats . Since the plane was not full would have been nice to change seat on the internet

their gluten free lactose meal is the best, I have never been satisfied with my flight meals. I definitely enjoyed my flight and the chair is very spacious for economy. I'm so glad Delta is my flight way back to NY.

Loved the check-in experience. Very friendly staff and not crowded. I did wind up with a middle-middle seat, which was quite uncomfortable. Always appreciate the very professional staff on TAL.

Was not able to check in online, so had to stand in line for 90 minutes to get a boarding pass, and I had no luggage to check. Why not let people check in in advance on line? Or at a kiosk at the airport?

Okay experience, seats had a very poor legroom and width. Very uncomfortable for long journeys.

the worst experience we had. they put connection label to our luggages with mistake and we had to wait for 5 hours to pick them up

COmpared to my experience in the business class of other airlines the food variety and offerings were meager. They did not have any cookies or crackers for snacking! They were unable to offer some other items. This has never been my experience in other airlines.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

Paying for reserved seats and never received the seats I paid for !! Just fake and a surprise out of their " box "

The flight departed on time and the staff was professional.

My mother got sick and dying and i have to change my flight and they charged me $2260 that is redisclose.

The airplane from IAD to Istanbul was too old. The chairs were to tight and uncomfortable. I continued my travel from Istanbul to Bangkok. This airplane was better and newer than the first one. Even food was better.

1st of all on February 27th Abu Dhabi to Delhi flight the seat wasn't comfortable at all, coming back the Lounge at Abu Dhabi didn't have anything. Than the Food in the flight

Overall mediocre experience. Check in was good. They're were discriminatory. They were not attentive, food choices were not vegetarian friendly. The food served was frozen.

Good range of movies but lacking decent tv shows. Wifi was really expensive on this flight, considering flights under 7 hours have a $9.99 USD charge for streaming, to jump up to $24.99 for a 7 hour 40 flight seemed a little bit of a rip off. Staff are inattentive, and really need to improve on the customer experience. The new airport is fantastic, as is the new lounge, a huge upgrade from the old airport and lounge!

In my opinion, Etihad Airways is a first rate airline except for one important element. On the day before my return flights, when I chose my seats on the Etihad website I was charged an additional $55 (US) in order to sit on the aisle. I was not at all happy about this additional "hidden" charge and I felt cheated.

Eine Toilette der Business Class war gesperrt und somit nicht benutzbar.

1.Aircraft Comfort: The aircraft type was quite small with non-reclining, cramped seats that significantly lacked comfort. 2.In-flight Entertainment: There was no provision of in-flight entertainment screens or Wi-Fi for the majority of the flight. 3.Boarding Process at New Abu Dhabi Airport: Despite the move to a new airport, which promised enhanced experiences, the use of buses instead of jet bridges did not meet expectations, causing inconvenience. 4.Gate Change Communication: A last-minute gate change was poorly communicated, resulting in a long and difficult walk.

Food was very good. Again tray could use a non-skid mat. I had a regular seat - comfortable - able to sleep undisturbed. Boarding was uneventful.

Boarding was quick and efficient. Ground staff were pleasant and courteous. Food was tasty, portions were good for me. Food containers kept slipping on the tray. Tray would look better with an anti-skid tray mat. I had the bulkhead seat which was very uncomfortable for couple of reasons. Aircraft is designed with no throughput to move across aisle to aisle. Passengers kept jumping over my legs to get from one side to the other to use the toilet. Secondly I had a mother and 9 month baby next to me. Mom had to hold baby for 12 hours in her lap as he did not fit into the bassinet. Half the baby was on my lap during the flight. Aircraft temperature was very cold - light attendant said it was the central cooling and nothing could be done about it. Movie selection was very poor old and outdated.

Crew did not cooperate… I just asked water twice for one crew member and she didn’t get anything.. and when I asked other crew member he gave me water and he was not respectful.. I kept Hindu non veg meal chicken .. when I get my turn chicken was not provided and then they gave me veg paneer and green peas curry which I don’t like..

Sits are very uncomfortable Don’t feel like to travel in Etihad. It was 1st time we traveled in Etihad now we decided we don’t want to travel in Etihad.

Coach seats are too tight. Seem designed for small people. Food different but OK. Staff helpful.

Self check in Kiosk did not recognize that I had prepaid for my luggage. This caused a 40 minute delay even though I had my British Airways email receipt for the prepaid luggage.

Great little city hopper plane. Unfussy and roomy. Nice little snack provided too

Some how I got “offloaded” even though I had my boarding pass Food was horrible Staff were nice and cheerful No headphones were provided

The flight was nearly empty so we were welcomed to spread out and relax. There was some turbulence but nothing too scary. The crew was lovely!! They engaged in conversation and were very friendly! The food is terrible!!! Horrible wooden utensils, they barely pierce the food or cut anything. I sat in basic economy and was very comfortable. Customer service at the desk was polite and helpful.

When bussing people to/from the gate, don't pack everyone in like a can of sardines and don't send the bus on its way if the plane isn't ready. Waited for about 40 minutes packed in this bus...both ways!

We were kept waiting at the gate for 2 hours without explanation

I travelled on biz class and f there is no water in the toilette to wash my hands I would expect to have this indicated somehow and not just finding out when I'm there expecting to be able to wash my hands and teeth. Also this is in general that it is always so rushy at the end of these kind of long flights. It is like we are sitting there for 9 hours and the last 1.5 hours just feels like I have time for nothing. Because food comes and at the same time we are close to destination everyone tries to pack their stuff and go to toilette and eat and everything :))) not that like I would know a good solution here I just wanted to raise this :)

On boarding, I used the bathroom. There was dirt (perhaps food) on the bathroom floor, and the sink in the bathroom was overflowing (old dirty water in the sink). There was zero entertainment, no charging capabilities for phones, and there was no food. The only complimentary beverage was a cup of water. This is atrocious for a 4 hour international flight. British Airways should be embarassed!

I have not used food or entertainment all other services I used were simply excellent. BA crew is always good in service. The BA Crew at anygiven flight is simply amazing.
