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

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

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.

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.

A great flight experience - great seats, lots of ROOM for legs & in the aisle. Great attendants! My flight cost me the same as ZipAir, the website was WAY less confusing & wonky - this will be my 1st choice for my next Japan trip. Very pleased / well cared for.

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.

Checking in was hard because we had to enter our middle name with our first name and wasn’t told to. The representative from underpricer investigated it and called me back. We were very appreciative for him.

They woke us up 2.5 hours before the flight was over? Why? If I'm on a long haul flight I want to sleep as much as possible. Also, didn't mention the mattress pads in business class so missed out on using those. The western meal of truffle, salmon pasta was the awful. Had a different fish dish on JAL that was great but that pasta was a mish-mash of too many random things that didn't make sense plus dry fish. Staff was friendly and helpful.

I loved Ryuichi Sakamoto's OPUS in the movie choice.

Too bad the plane didn't work after we taxied out to get in line for take-off. We went back to the gate and waited for almost 90 minutes for them to find a plane that worked. Waited another hour to board. When we got to Rochester we waited for over an hour for our bags to appear. The agent said they only had three people working to load and unload baggage. A one hour flight took an extra four hours. It would have been faster to rent a car at JFK and drive to Rochester.

One of the best economy flights I’ve ever taken .

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.

The staff on Singapore Airlines was incredible. I would like to commend LS Reuben from my SQ37 flight on November 19th, 2024, from LAX to Singapore, for his outstanding service and care. During the flight, one of my earbuds—brand new and valued at nearly $300—fell out and became lodged in the box controlling the in-flight entertainment system. I was understandably upset, but Reuben went above and beyond to assist me in this tough situation. Reuben demonstrated exceptional determination and empathy. Instead of suggesting we wait for an engineer, he immediately took action, spending almost 30 minutes searching for the earbud. He even got down on the floor to ensure it was recovered. His genuine concern and persistence made all the difference and turned a frustrating situation into one where I felt truly valued as a passenger. Reuben is a shining example of the remarkable service that sets Singapore Airlines apart. His dedication and willingness to go the extra mile left a lasting impression, and I want to sincerely thank him for his kindness and professionalism.

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

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

Crews were very caring and polite. Washroom was surprisingly clean. Overall experience was good , only food choices was very limited. Thanks

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

They made 22 hours aboard aircraft very enjoyable. I was very impressed with the attention to detail and level of service. Singapore airline will be my preferred choice going forward.

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.

When comes to Taiwan airlines China airlines is the best rest are pure trash

flight delayed 45 mins - missed connection - 1 hr layover became 8 hr layover waiting for next flight -

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

Horrible airline. Missed my baggage and don’t want to reimburse for the basis items. Pathetic customer service

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

I was really impressed with the experience it was my first trip overseas. Nice staff

Not enough food for everyone. . Always run out of food when we ask

I was amazed at how clean Cathay Pacific planes were compared to our US domestic airlines. Everything was great all but the food service I was just okay with. Shorter flights with other airlines usually provided more meals and snacks that I have been on. Almost a 16 hour flight just two meals and no snacks with Cathay Pacific. Even ran out of what I wanted for one of them. Other than that top notch!

It would be nice if they could have a choice of both gluten AND dairy free menu. Lots of people have problems with BOTH. I also could not get on their website to check. Phone verification issues etc( not all of us have our phones on roaming. I tried over an hour!

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

Cramped seats. Audio jack for the in -flight entertainment was broken.

Service was great, we had bad departure and bad arrival due to weather, but that we cannot control. Hats off to the pilot!

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

The free snack options are pretty pitiful for a 2.40h flight.

Preferred the UA flight compared to the Air India. The seats were more comfortable and the food was good enough.

Ridiculously slow disorganized boarding, ended up 35 min late and people missed connections

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

It was so uncomfortable for 14 straight hours it was torture

The plane doesn't have any screens, so it was impossible to watch a movie

Something wrong with the plane so had to deplane and waited over 2 hours to finally leave

The flight crew was wonderful. We were delayed, however the pilot and crew made the delay enjoyable.

I didn't use the entertainment feature. I can't fault that. That was my choice. I could have opted for a bigger seat. Again, my choice. The crew was excellent on all of my flights. I don't really fault the food choices. (I'm one that's grateful to eat). All of the flights left on time or arrived early or on time. Grateful for the assistance that I received when checking my bag at Heathrow. (It was early...hard to think)! I hadn't flown in 17 years. I would consider choosing Air Canada again in the future.

Was nice to have plug in and TV screen on seat back. Didn't have either on rouge flights. Staff was excellent.

Announcement of flight cancellation when we were at the gate for boarding. Yelling that the only thing they would do is hand out taxi or hotel voucher. Group of us were travelling to the same location and we were not accommodated to travel together. I was sent to Montreal with barely enough time to make connecting flight and when I got to La Guardia my luggage was sent to Newark. I got a damaged suitcase next night (after 11 pm).

Flight took off little late and landed back at YVR after an hour without informing a reason to the passengers. Also, second time also got late but an hour to take off. Therefore, I had to change my plans during due to delay in landing to SFO roughly about 6 to 7 hours.

Lots of selection for entertainment. Fight was comfortable. However. The flight was delayed multiple times. And the delay caused us to miss an important mwwting.

More room for carry-on. Or having people bring correct carry-on.

The baggage handlers at Toronto did not load anyone's baggage onto the jet. We sat at the carousel in Pittsburgh for a half hour before anyone told us.
