My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Great to have actual hot tastey meal on a flight. Well done

All in all the flight was good. Love the fact that for airline food it was piping hot

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

I requested an aisle seat and got a middle seat The flight gate was changed and the flight was delayed

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience

The premium economy seats were not that great. It could have been more premium than economy seats.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

I liked everything accept the delay try to improve in that area

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".

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

Checkin and boarding staff at Delhi Airport is not cooperative with passengers Their behavior very humiliating . They don’t allow Lap top bag and Ladies’ purse/vanity bag which most of the airlines allow besides cabin baggage and check in baggages. They try to charge extra payment on the pretext of small variations which normally other Airlines staff don’t do. Airline staff should be courteous & cooperative but check in staff of Emirates Airline at Delhi was not so at all.

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 !!

Good but needs to improve cleanliness Coffee serve cold Needs to raise standard serving food Otherwise good

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

The lounge Emirates uses at Jeddah airport is horrible even with the opening of the new section. Food selection is poor and never enough seating . Staff are not friendly. Boarding process at Jeddah always an absolute mess

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

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

Good staff, good intent, decent entertainment. More seat space would always be of benefit

For a short flight, Qatar Airways offers very good onboard service.

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

The staff at the check in lied. I requested aisle seats he said he gave me aisle seats. In actuality he only gave me aisle seat for 2 hour Karachi to Doha flight. From Doha to Dallas flight he gave me middle seat .

Boarding delayed, no communication. I left the lounge, and heard a final call, boarding started after a 30 minutes.

Overall good but staff in the place looked extremely tired after 8hrs in 14 hrs journey and then service was cut short and response time for calls increased in later part of flight. Food was ok not astonishing

Very very poor service. Authorities must take action against this airline immediately. Total failure to follow the rules and regulations of an international airline

Boarding process was terrible. Will not travel Qatar Airways if I had an alternative. The food was one of the worst, even for airline food.

Food could be much better. Entertainment needs lot of improvement. The luggage came out open with broken bags. The flight landed at 3:15 PM in US and by the time bags came out it was 5:15 PM or so. Staff at airport was aggressive and not polite.

need to improve management and air hostess services. Rest of it’s OK.

1st time with. Etihad Airways and it was amazing from check in to crew. Great flight.

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!

Very unfriendly team. It was very difficult to get a cup of coffee. Legroom was extremely small. Old, dilapidated plane.

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.

The flight was small and was not cool very bad

It feels like the seat did not have any cushion just plywood. The seats are so compact that I could not even move at all and I am slim. Just imagine someone else. Singapore Air and Emirates are far far better than this. Do not even travel for free. For a 12 hour flight sitting on a plywood is horrible experience and on top of that the person at checking counter at NY was worst and rude. Plus they charge arms and leg for everything. I think they would also start charging for belts and oxygen also soon. First and last time flying with Ethiad.

I request kosha food all my flight but this flight didn’t imclude my kosha meal.

Check in was quick and gentleman was very nice and friendly, during flight crew members were polite and attentive, food wasn’t as it should’ve been. Entertainment section needed to be updated i.e add new movies

Dear Etihad Airways Customer Service, I hope this message finds you well. I am writing to express my deep disappointment with my recent flight experience on Etihad Airways, which took me from India to NYC via Abu Dhabi. My flight details are as follows: [Flight Number] on [Date]. My overall experience was marred by a series of significant issues that I believe warrant attention and improvement. These issues include: Bad Conditions of Washroom: The state of the washrooms on the flight was far from satisfactory. They were inadequately maintained and lacked the level of cleanliness one would expect during a long-haul journey. Seating Space and Comfort: The seating arrangement left much to be desired. The seats were cramped, uncomfortable, and the legroom was insufficient for such a long flight. The seats did not recline as expected, making the journey quite uncomfortable. Cabin Cleanliness: The cleanliness of the cabin, including seats and tray tables, was not up to par. The lack of cleanliness impacted the overall comfort and satisfaction of passengers. Excessive Noise: The flight was notably noisy, with disturbances and loud noises making it difficult to rest or concentrate. The noise levels were considerably disruptive. Food and Catering: The quality and variety of meals served on the flight left much to be desired. Furthermore, there were issues with accommodating dietary restrictions, which is crucial for passenger satisfaction. Hygiene and Sanitary Facilities: The condition of the restrooms was subpar, and essential hygiene supplies were not adequately provided. This falls short of expectations for a long-haul journey. Overall Experience: Regrettably, the combination of these issues significantly affected my overall experience during this long flight, making it far from the comfortable and enjoyable journey I had anticipated. I understand that maintaining high standards on long-haul flights can be challenging, but I believe it's vital to bring these concerns to your attention in the hope that they can be addressed and improved upon in the future. As a loyal Etihad Airways customer, I had higher expectations for my journey. I kindly request that you take these issues into consideration and work towards enhancing the overall passenger experience on similar routes. Your attention to these matters is greatly appreciated. Thank you for your time and understanding.

Excellent service and great help when i traveled with broken leg

They allowed some guy to move seats after 3hours of him being next to someone very sick, There were several empty seats, but they moved him to mine. I find that incredibly inconsiderate and should not have been done.

Excellent. Very nice and comfortable business class. Only negative is that it was difficult to hear the pilot’s announcement.

Food not so good. Need more veggies and whole grain especially the late food. Couldn’t figure out how to use the entertainment system.

Check in was horrendous! Economy took 2 hours before seeing an agent. Business class was 0.5 - 1 hour.

The first class flight itself was first class, however getting to the airport and getting through the airport was agony. The BA flight sat on the taxiway for ages and caused us to miss our connecting flight which meant half a day lost. Our return flight on BA was cancelled so a dawn flight was made and we lost another half day. Goodby BA

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

There was some delay at Heathrow where a machine needed to "start the engines" wasn't available and they couldn't even find the team tasked to do it. Unacceptable. Caused about an hour delay and seemed unnecessary. Also saw several passengers abusing the overhead luggage situation, having too many large bags and not leaving enough space for others. The crew was good and the refreshments were good in quality and quantity.

They cancelled our ticket, gave us no warning, they reissued it 4 days prior to trip and it was cancelled again when we got to the airport- very stressful, the flight was overbooked so they drove us across Milan to malpensa

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso
