Website from the 1990s, super frustrating customer support, inflight experience merely OK - more like United than e.g. Emirates

Website from the 1990s, super frustrating customer support, inflight experience merely OK - more like United than e.g. Emirates

The seats are significantly more comfortable than US airlines and the staff are much friendlier. The food is also much better, as they are particularly accommodating to any dietary restrictions.

The team members are extremely attentive to make sure you have the best experience.

Could had been better if they include in their menu some western food.

They 7 seats in one row for Business class while most business class for other airlines are 4 seats in one row. the seat was narrow. the Toilet was so smell, dimming light, no water out of faucet. Terrible.

Difficult to access advanced check-in online. No way to understand why it wouldn’t work. Call center not answering. Email for answers took days to respond, Kind service at the airport and on the flight made up for disappointing service before flight.

Courteous and helpful employees. Comfortable seats and temperature of aircraft . Did not need squid in my salad but glad to have the menu information advising me of what it was

Everything was great, except the Wifi, but that's understandable.

I purchased the ticket online and went to do online check in amd the app wouldnt let me. I went to the airline desk and they couldnt confirm my ticket in their system. I ended up having to buy a ticket from the airline directly and paying twice for the same flight. The app wouldnt lwt me check in the kayak purchased ticket until after my flight was taken off.

The plane was dirty, there was trash in the seat pocket in front of me.

It was very good experience on board to Sydney with SQ.

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

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

Flight was delayed by baggage loading onto the plane. This was attributed to "inclement weather" (some moderate rain) which could be said to be beyond the airline's control, but the problematic part was that the plane was boarded and doors shut so that passengers sat in a cramped plane with rising temperature (full flight) for an hour. The airline was aware of the status of baggage loading, they could have deferred boarding to keep passengers comfortable.

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

The staff were amazing and very kind. The seats recline a little too far back and are up close when sitting behind.

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

Maybe add a seat trade app for flyers that didn’t get seats together

It’s been awhile since I have traveled on United. I, along with my family who were on the flight noted how smoothly everything went . Boarding, flight crew and service was excellent.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence.

There's just no way to sit fully upright and comfortably in these seats. There needs to be 2 more inches of room, and that's not something that only one person on the flight needs - the whole flight needs 2 more inches of room. If that means you sell 6 less seats, so be it. It's too close for anyone. Forcing people to pay for "premium" economy just to get "barely enough space to breathe" isn't really an answer to that.

The crew were very nice. The Chocolate is good and v there’s no entertainment. Thanks

The crew were very nice. I would have appreciated a pillow for comfort. I had a special meal that was sloppy, but the salad was great. Thanks

I liked all the informational texts. I always knew where to go and when .

I feel bad, but Swiss airlines is not an airlines I will ever fly again. Their cabins are basic, seats are extremely uncomfortable, crew is a hit or a miss with service. What's worse is how they make you feel they are there to make money and not make your travel needs be met or make your travel a pleasure. They charge for 2nd bags, seat selection and felt like a budget arinines frontier/spirit airline attitude and approach. Their business class is from the early 2000s, basic. Additionally, planes going to India, are old, falling apart and not maintained. Even the crew mentioned this is typical of the airline having older planes going to India. Panels detached and loose or stuck with duct tape, seats scruffed up and dirty, seatbelts roughed up. The scariest thing was when I saw a window panel next to where I was sitting loose and dangling. The crew mentioned it's only cosmetic and assured the integrity of the plane was inspected by the maintenance crew. This is where they confessed about planes going to India being old. I UNFORTUNATELY would NOT recommend Swiss airlines to anyone and will NEVER fly with them again!

My one complaint was that while we boarded using the standard enclosed gangway, when we arrived at SEATAC, the ground crew were slow to hook up the stairs. After reaching the tarmac we had to walk up a long ramp all outside in 35° weather. We just came from Bali and did not have warm weather clothes. This was in addition to having to collect our bags in Vancouver, take them through security again and then having to show our passports 4 more times all within the Air Canada section.

So we didn't actually go. We were hoping to go for the Inauguration of the first female president. When That Guy got elected, we bailed. Unfortunately, we got basically none of our money back, despite having travel insurance. Would not fly with Air Canada again unless I had to.

flight was delayed, there was open communication about the delay the delay pushed way past the posted delay time and

Ok Did not like that the second leg of flight was moved earlier making it a rush to make it

This was my first time flying on Air Canada and the experience was good and pleasant enough, great crew members and the price I paid was amazing,

This was my first time and the experience was good and pleasant enough, great crew members and the price I paid was amazing,

Overcharged by either United or Air Canada. Abuse of access to my credit/debit card.

I was overcharged either by United or sister airline Air Canada. It's exhausting dealing with companies nowadays that irresponsibly abuse access to credit/debit cards.

Air Canada is not only the worst airline in the business but the worst business in history.

Your crew was so so so wonderful Only thing sound be great if you kept some phone chargers and converters rest 👌👌👌👌
