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

They made me check my carry on even though there was room We un boarded in a strange way but overall it was good

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

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

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.

A pc of cake or biscuit at least. The airport was like a maze need to take another bus to the main terminal to immigration.

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

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

Flights were both delayed. No luggage on arrival for the whole plane and no contact since submitting a PIR.

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".

Flight got canceled without any prior information and it caused lot of trouble

Nice selection of movies and TV shows. Plane was generally nice, not the newest but nice nonetheless. However, Emirates should have cancelled the flight, as hardly any flights flew out of Dubai at the time. Flight delays and cancellation was poorly communicated and passengers were left guessing and to their own devices on what to do. Connection desks were staffed too thinly, there was one desk with more than a hundred clients and just one poor lady. When I had my flights rebooked, I was told meal vouchers can be scanned using my boarding pass, nope. Was told to comeback for my hotel voucher, none. Had to book my hotel voucher the usual way through Dubai Connect despite having been told twice to comeback to the counters twice.

Didn’t like it at all. Cabin crew unfriendly. Very bad experience.

Food is really bad, not to the Emirates standards. Coming out of Houston airport is very confusing,

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 !!

They had superb boarding (started an hour before flight time). Timely pushback from them gate and an early arrival. Flight and service was very comfortable. I wanted to move my flight to an earlier one, only thing was there was no one at emirates in Heathrow to help. Had to call the call the center and pay to change. There were ample seats on the flight though

More leg room and comfortable seats at least for long flights

we were late to get to this connecting flight and SWISS decided to wait for us . Very nice of them

So terrible. They would not rebook me for a flight until 2 days. I had to spend so much money to get my own flight. They were rude and not helpful.

Super friendly crew. Leg space and entertainment system are below average

The plane was so hot upon boarding. Their boarding process was so unnecessarily long. Service was subpar.

Swiss ground crew was again at its prime and although I’m United 1K (Star Alliance Gold) they created problems with my hand luggage - while other passengers were boarding with more handbags and larger hand luggages, were critical on my 2 young kids attending the lounge with me and boarding the plane with me on the priority lane.

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

Bag lost. Lost bag recovery process is an unsatisfying customer experience. Because 1) bag is still lost but also 2) the process is outdated and form-heavy and 3) in our case also involved a long line.

Not exceptional but all good. Business class seats are like the domestic Mint class on Jet Blue. Comfortable but not exceptional. Food is good but not superb. Flight attendants were better on India leg than Miami to Zurich. All India staff was more professional and service oriented. Very polite and service with a smile.

Motivated and friendly crew on a somewhat dated but well kept plane. Hd seats in economy may section, so legroom was excellent.

United Airlines flights serviced by Swiss Airlines provide for zero communication with Swiss Airlines almost impossible to contact Swiss airlines to make seat selection, upgrades or changes. I won’t do that again if it can be helped.

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

Never flown with LH before so all in all wasba good experience. Also good to know that approx 24hrs prior the flight opens up for being able to organise the seating free.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

Great flight. Left on time, not very crowded. Quiet and the right temperature.

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!

Very very poor. Reliability is the main issue. The flight from Bangalore to Frankfurt was delayed by 8 hours and hence we couldn’t make the flight from Frankfurt to St. Louis ( which was later canceled by Lufthansa ) . Bangalore airport lounge 080 is EXCELLENT. The shower in the lounge is first class. Wished they had some extendable lounge chairs for sleeping for the weary passengers. FRANKFURT AIRPORT IS HORRIBLE! WILL NEVER EVER FLY IN OR OUT OF FRANKFURT. There is no jetways for the Lufthansa flight and the bus took so long to reach the next terminal. We had to clear immigration and security checks again and again though we are transit travelers.

My luggage never arrived to Zurich. They can't confirm when it will arrive

Late again. 3 out of 4 late. One cancelled flight and one lost bag.

Charged an extra 65 pounds for overweight suitcase, Not told how much overweight but had no choice but to pay the price. Compare to Delta Airlines where I flew internationally a few days before with this suitcase and no extra charge by Delta. Comfort was horrible. I am just under 6 feet tall, and good that the flight was only 1 1/2 hours, because my knees were in the seat back in front of me the whole flight. I felt that my knees were part way up to my chest. No reason to have the seats that close. I will say to the positive was the flight crew, very friendly and efficient.

The flight was delayed as they were waiting on catering. Catering. Was eventually delivered but they still had no food. No meals for us in business class - just a bag of nuts.

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

Air hostess delayed providing food and then pulled away the tray before i finished eating

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The flight was on time and the crew very professional. Everything went as expected and I will use BA again for this trip.

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Very bad plain although I paid A business class ticket I was stuck in a stiff fixed seat without any entertainment or Wi Fi for 5 hours I will never ever book a flight on British airline.
