Very smooth flight. Superb crew, great food and service. Slept most of the way. Excellent airline.

I was sleep when they brought the food. They had put a note on my seat. There was no food when I asked for food later. There was just one main meal served in this 14 hours flight. They offered me sandwich with ham which I don’t eat since I am pescatarian. Long story short I had to wait to get to TPE to get something to eat. I am extremely disappointed from the service. I have been flying EVA since I was 1 year old. Perhaps no more EVA for me. Seems EVA glorious day is long gone

Excellent food. Good service. Crammed Premium Economy seats. I Asked to change seats during check in. They told me the flight was fully booked. But on board I saw empty seats where I could have been easily relocated.

Good. Please add a non- applicable category to your questions.

The app was awful. No accurate info. Paying for internet is a negative (Delta is free). The crew was very nice for the most part although you are not guaranteed to get good service. Some crew would ignore requests for things as simple as a cup of water if you were sleeping when the first serving was made. Food was great. Male crew member was exceptionally kind and responsive.

EVA air was nice. It was the first time I’ve flown with them. The poor entertainment choices for 2 long flights will make me think about choosing them next time. I didn’t know if would effect me so much but I couldn’t sleep and it added to the stress. The food was terrible for me but I couldn’t find how to inform them about my diet when I bought my ticket.

It was a good flight. I would highly recommend it to family and friends.

The employees were professional and efficient. I consider myself a traveler but have trouble with the international fare served on airplanes. I admit Americans buy their food in the supermarket and we typically don’t eat the ligaments and cartilage. I know that is whiny but as I age, I dislike it more. At least things weren’t covered in cheese. The desserts are terrible! My neighbor didn’t eat her bread so I asked if I could have it. First time for everything but had been traveling a total of 27 hours and was hungry.

The night flight was only 2/3 full, which is always a plus. Room to stretch out for sleeping. Gracious stewardesses, attentive, and slim/attractive (which is rare these days). Good food, and curtesy wine.with meals. Comfortable seats and decent leg room (economy class)

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

Food could have been better. Too many passengers getting up and down all the time.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

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

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.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

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.

The food options and quality could use some more excitement and variety.

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

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.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

Flight delayed over 2 hours . I was flying bussiness never got food cause they ran out of what i wanted

Flight was great my baggage was on time everywhere but my bags had been handled ruff cause they got damaged.

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

Poor and identical to the first two legs, except for the crew who were patient, professional and of pleasant and jovial disposition!

The entertainment would not work. The comfort of the seats leaves something to be desired, pretty uncomfortable.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.

Cleanliness of seats, trays, storage pockets need more attention, but everything else was good.

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

One of the worst check in process at the DIA as well as the boarding counter Changed seat at the last minute and assigned middle seat while I paid for window seat. Requested many times but to no avail . horrible customer service and very poor process Requesting refund for seat that was changed last minute

Good overall flight. Excellent crew. Food options could be improved.

Vegan food tasted good. Restroom could be kept cleaner. Seat tray table was a bit tilted so food tray kept sliding down a bit. Flight crew can be a little more friendly, caring and approachable. Their faces lacked smiles and tone was stern.

Flight was delayed then we had to redirect for medical emergency during which time we had no information on what is the plan. The connecting flight was also delayed.

Seats are not clean inside the very dirty and need to improve

Professional & courteous cabin crew. Food was very good even in economy class

7 stars hospitality and an excellent service by the Turkish Airline entire team. Somehow, our membership numbers for mileage points were not indicated on our boarding passes issued at O’Hare Airport by the Turkish Airlines check in desk. During transit in Istanbul, I brought to attention of customer service Turkish Airlines. Please have our mileage points posted to our membership account from O’Hare Chicago to Lahore for both my wife Kaukab Shirazi Thank you

Terrible boarding experience, with an incomprehensible assignment of priorities. “Fast track” was the slowest. Poor system planning.

Awful. Flight screen didn’t work. Seat didn’t recline.

I liked nothing about this flight nor the incredible lack of service and communication on this flight from the Captain to every staff member. Arrogant, entitled and lacking any kind of basic customer service

Everything should be better, terrible flight and airport service. Delayed for 6 hours, flying around for 1 hr, and keeping us on a plane for another 2,5 -3hrs.

The plane was dirty. It appeared that Air Canada did not know vacuum cleaners had been invented. Second, the overhead bins were about 1/3 or 1/2 the size of "normal" bins. That was a problem. The worst was disembarking in the weather in Montreal. I have cold agglutinin disease. That means my red blood cells clump together and then are destroyed when exposed, even by breathing to cold air. A few seconds of exposure can be dangerous. I am now experiencing extreme fatigue caused by the anemia from that experience. I should have had more assistance descending a narrow ramp and then traversing, even if only a few feet, of icy pavement. The blowing snow penetrated my facial covering and has caused problems.

Good airport. Good entertainment on the big flight. Did not have a good way to prop up or mount my phone/ipad

I booked my flight ni November and was placed on standby? How does this happen. Flight was 1 1/2 hours late departure plane was switched to a smaller plane easy to tell this is a government run company they don’t care about anyone

Boarding was a disaster one person checking in 200 people took 25 min to check in zone 1&2.

Old, noisy plane, bad coffee, delayed. Flight attendant was very nice.

Boarding could be improved, no need to wait after a previous group is completed

We boarded 1.5 hours late. Long wait for the bags when we got to Mexico City. Long wait to get on plane with people mover truck. Friendly staff. They answered all questions as best the could. Such a long, long walk from the plane to customs. Thank you, Michael A. Burris Cambridge, Massachusetts USA
