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.

Food was great, Entertainment was bad, movies were not current and just did not have good variety. Granted I was tired so cranky might have played into my evaluation. Overall based on cost I definitely would fly them again. I am a million mile flyer on another airline, the service on JAL really beats all airlines.

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.

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

Underpricer was terrible. They wanted to charge me $150 for a seat asignment. Kayak is responsible for letting this happen. Please let me know if this is going to happen in the future. If it is i will not use kayak in the future.

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.

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.

Well, this is my second flight from THE first one that I took and this one was from Manila to Guam. The flight was comfortable. I did end up in first class. However, I had to fight for it a little bit, but when I went to Guam, I had to stay an extra night there, which was accommodated by united Which I'm pleased for that. The only thing that I have to say is when a situation happens with a cancelation. And you got first class guests very important that you accommodate and make sure that they have their flights before everybody else does, because we pay big money for the service and it is not cheap also. Take note There are things that we have planned as well. So this kind of damaged the tail end of my vacation, which I lost out in $2500 worth of car rentals hotel fair in Honolulu, Hawaii. I'm really hoping that I can be reimbursed at least that money from the insurance that I have on the trip through united. I will be submitting that in as well. When I'm back in the United States, because I'm currently in Guam. Staying good night. I'm waiting for my next flight out. For tomorrow morning..

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.

Very modern plane. Good seat spacing. Meals were good. Screens had tons of movies and worked

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Beijing PEK to SFO. I had an economy seat on this flight. The seat comfort was acceptable. My main complaint is with the FA’s lack of personality and absence from servicing the plane, specifically restroom care (I wish I could share a pic of the restroom that I captured) and care of travelers—drink cart/availability of drinks. I'm amazed at the level of service on other International travel where a passenger is most often appreciated.

If you want your flight to get delayed constantly for 13+ hours and given a 10 dollar food voucher the. I would say take air canada. Worst experience ever.

My flight was cancelled and I was left to figure out where to find a hotel, something to eat and how to get a new flight at 11:30pm. Wasted a day. Thanks, Air Canada!

flight was delayed 6 hours for weather, then cancelled because of the crash in toronto, but none of the links to cancel or rebook my flights are working

They kept changing the gate (6 times in 30 minutes) and then left us on the plane for 4 hours before departure. Likely was the storm, which is understandable, but the lack of communication and the e constant running between gates at opposite ends of the airport really threw me and my friend for a loop.

Legitimately everything about this flight was awful, was also so delayed I never want to use air Canada again

Terrible all around. Flight was late and airplane was very uncomfortable. The crew were unhelpful and hid in the back. Did zero work. No entertainment.

Because I am quite tall a bit more leg room would have been more comfortable. Out of three seats I had the middle one, unfortunately.

I like the free beer and wine but not the delays to the departure time.

Never again flying economy on Rouge!!! Literally like sardines!!! Will try to change to better seats 3 seat arrangement only so so if traveling with family. Who wants to squished to stranger!!😖 Can’t say enough bad about this!!!

I booked and paid extra for exit door seats also pre paid for my luggage air Canada changed plains and I never got what I paid for and they made me pay for luggage again they also did this to my wife. They are the most unorganized company I have ever dealt with. I am sure I will never see the extra money I paid for the seats or the recharge for the luggage. They are subsidized by the taxpayers and don’t give a dam just a horrible way to do business
