The seat in economy class and legroom in Singapore airline are narrower than Korean airlines! I don’t have that comforting feeling flying with Singapore air as in the past!

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

Everything was great keep up the good work 😁, can't ask for more.

Really enjoyed the flight. Our flight attendant on the way back SIN-LAX was exceptional I didn’t get her name but she was so kind and went above and beyond to make sure I was comfortable. I had a bit of a panic attack and she checked on me a few times to make sure I was ok. Really appreciated her attention and service. Thank u

Timing very good from sfo to Singapore and service was awesome and economy class seats are great overall very good experience thanks

The seats were more narrow than at other lines. Food was mediocre (economy class)

The crew have great customer service but their economy seating isn’t the most comfortable for a 220lbs+ guy and the food wasn’t bad, but wasn’t exceptional, either.

Food option Hindu veg to Hindu non veg request was unheard

This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

Service excellent would chose Singapore airlines as my first choice

Overall I was quite pleased with the experience; the cleanliness; the polite and attentiveness of the cabin crew; and the delicious food options.

It was great, a little more leg room would have been better particularly since we were in premium economy

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!

Excellent comfort and entertainment. Service poor..Food average with little choice.

Comfort good. Service as usual poor. Cabin temperature as usual too cold, about 15 degrees

The plane was clean and well maintained the crew members were professionals and friendly and the food was good

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.

On this flight, about the last 2 hours the captain kept the cabin too hot. It appeared like the ac was off.

Airline did not have enough vegetarian meals for all guests, and crew were not adequately trained to handle this.

Boarding was a mess, no one managing the queues. I got my meal as the pilot announced starting commencing descent and basic drink not available. No air bridge so takes forever to deplane the A380 onto buses.

I haven't flown Swiss in a long time. I was disappointed that after paying $14,907 for 3 business class seats, we still had to pay another $200 for a single business class seat. All the window seats used to be single seats. Now it's every other one and if you want a single seat it's extra. Also, The double seats do not have pods or any privacy. We landed in Chicago after a long 10 hour flight and our connecting flight was on United. Because we do not have status on Swiss, we were not allowed to use the United lounge, even with business class seats. My father is on crutches and we had a 4 hour layover. No lounge was also disappointing. All of my status is on British Airways so I will go back to flying BA. We flew Swiss because my father did not want to go through Heathrow. On a positive, the crew were super nice and accommodating for my father who had recently had hip replacement surgery. Food was okay. I"m not a good person to critique the food, I never like airplane food.

My luggage did not make the connection and 4 days later I still have not received it.

I took this flight to be able to fly with Swiss instead of Air Canada from Geneva.. The AC planes have a better outfit in Business class than Swiss, but the service aboard Swiss is really best, first-class, as is the food and beverages. Though using the same plane model (A330-300), the interior setup of the cabin starts to show its age, but IMO the planes are better serviced by Swiss than AC. I had in my recent trips with AC way too many technical problems that led to delays or even complete cancellation of my flight.. Their fleet is aging (average 20+ years) and the maintenance has taken a toll compared to years ago. Cutting costs in every corner has to be paid sometime by someone, and it's the travelers at the end that pays for it. Unfortunately for me, flying directly to Zurich puts a much longer after-fly trip on me than Geneva.. so I might go back to direct flight YUL-GVA, even if I don't like flying with AC.

We are flying with Swiss for a long time but this time was terrible do to are flight cancellations we are in some bad hotel with out normal food

Terrible plane small airbus good for a 1 hr trip I booked business as it is. A night flight and 4hrs trip it was an ordinary economy seat with no one next to me what a joke what a stupid decision to buy business

For the price of the ticket it's probably the best service in the world

Everything was great except food . It as okay not good not bad

Seats are too cramped, but that is a problem with every airline. I actually enjoyed the meal served.

better announcing at the gate prior to boarding and better organization of various gps

Ghe issue was with the delay caused by the late boarding. We had to run to catch our next flight, barely made it and then our luggage didn t arrive with us. Really bad organizing.

Jia yung was the flight attendant that made this a miserable flight.

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

AC not working, just slowly blowing room temperature air. Long taxi time does not help as well. Sweating all over the whole trip.

Did not take as cancelled 3 time so took another airline

It was a 2-hour flight so they didn't have much time for serving food. There was some turbulence so they could not serve hot coffee or tea for the safety reason. Good service, good tasting food, nice plane, a little bit of delay.

The IFE is quite unconvenient if using our own device. Not all passenger brought their own earphone/headphone.

Ok, but legspace on MH0127 from Kul to Per was too small. It was not possible to tilt my seat which I don't understand because the seat in front of my could do it. So I didn't rest on the flight. Also, the crew was probably understaffed because it took very long time to take trash after the meal. Everything very different from the flight with Malaysian Airlines from London to KL.

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

An overnight Doha to KL. Great sleep, good service and tasty food in business class

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

They overbooked the flight by 3 people. It is completely unacceptable to tell 3 people, with paid tickets, that need to get home for children etc, that they need to stay another night. No compensation. No apology.

It was a short flight but everything was great! I would fly with British Airways again.

Delayed flight due to lack of crew caused me to miss my connection

Please make sure the number of seats matches the number of overhead bins and passengers don't carry on more than one bag.

It was difficult to board from London to accra. Had to get there an hour before and almost missed the flight. Did not get enough rest time at the lounge

Seating is tight if you don’t upgrade. Food was decent. Boarding and unboarding was efficient. Smooth flight. Could make upgrades more affordable

American Airlines seemed to run a 'dry' flight. No alcohol was offered at any point with meals. Breakfast was a bit tasteless. The 'hot pocket' whatever that is, was horrid breadish pastry with very little filling. Decaf coffee was horrid. Seats didn't seem as wide or spacious as usual, especually for a ten hour flight.

We found the bag drop/ check-in proceedure at T5 unnecessarily complicated. We paid extra for seat selection in advance and were allocated worse seats at T5. We found the check-in person was not particularly helpful although the the staff at the gate were super good.

Very dated plane. Seat was firm and uncomfortable. Entertainment system almost laughably outdated. Poor audio. Picture was always too dark.

The worst travel experience of my life. Boarding chaos, delays and disorganisation at every stage. The worst of many was sitting in freezing temperatures for 10 hours whilst asking all cabin crew to turn the heat up to no avail.
