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.

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.

Excelent service and plenty of food and drinks during the flight. Flight crew very attentive to our needs. Leg room between rows are very disappointing.

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

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.

leg space better than expected. two washrooms for one plane isn't enough.

My suitcase was destroyed. The top part where the handle is is completed broken. And unusable now.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

I love United was disappointed we had a two hour delay, however the Pilot did say safety first.

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Food and flight attendents with positive dispositions and friendly behavior, more professional attitudes

Wonderful and fast TSA checkpoint. The line was fast and our gate was close by

The gate was too far away for the connecting flight

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

It was a lovely flight. Very attentive crew, comfortable seats, good food and entertainment. Highly recommended. Only difficulty was with their app.

Terrible. Flight was delayed for hours and we ended up arriving at our home at 4am after 20+ hours flying.

Staff was friendly helpful also good timing I rate it a 10 out of 10

Flight was cancelled around 45 -1hr minutes before scheduled take off time due to mechanical issues we hadn’t even boarded yet. Had to reroute to Orlando so someone had to drive 2 1/2 to come and get me… the alternative was go through Toronto and get a later flight which didn’t work for my schedule. The flight attendants barely gave anyone a smile…not the same as flying when a client/passenger was important. Very disappointed. By the way I have never ever made a complaint online about any company with feedback…even when I probably should have. The only good experience was the boarding desk associates who were very professional and got me on another flight with my checked bags…very nice team.

Actually as my experience with air Canada from Canada to Newark it was crazy for me because it was a lot of delays which for me it shouldn’t be like that, but I was able to coup with it so that was my experience I hope next time they will do good on that thanks.

Boarding was challenging as we had to use the stairs from the tarmac. Stairs are okay but a roller bag makes it challenging.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

All was fine. Weather was a bit stormy, but nothing kayak can do about that! 😊

I paid for a comfort class seat and was seated in economy.

Once again our Air Canada flight was delayed! I'm hopeful competition arrives with other airlines soon and maybe they will make a better effort to be on time!
