Although the flight is listed as 17 1/2 hours, actual flight time was only 16 1/2. Bring a sleep mask to ensure you rest during your flight - it helps reduce so e of the flight time and helps you arrive more refreshed.

The Singapore Changi airport if huge. After getting of the aircraft, the walk to immigration control was long. Once you get to the control area, the process was quick and easy.

Premium Economy seats were more comfortable than other airlines I have recently been on. Great staff. Food was unremarkable.

From checking at the airport to end of flights, attentive and caring personnel, comfortable seating, great food. I plan on using EVA again. Thank you, all.

Very nice, I feel I got good value for the price.

Amazing one of the best airlines i have ever traveled with. I live with medical issues called psoriatic arthritis and was in pain on the flight. The flight crew made sure I had fresh ice pack ever hour. Going above an beyond with service and care ⭐️⭐️⭐️⭐️⭐️.

Certain flight crew member were rude and short with me when I asked questions.

We were very impressed with the modern plane its amenities, as well as the services of flight attendants.

The crew very accommodating and food too is good. Keep up the good work

The crews are very efficient. Other airlines should learn from them when it comes to boarding and departing from the airplane. They also display efficiency in serving meals. They don't keep the aisles blocked for hours like some other airlines. The food is poor. Generally the food was unrecognizable and poorly prepared. The only thing that made it better than US flag carriers is that there was a fresh fruit bowl with each meal.

Very good service and food. Crew was professional and considerate. Cabin and restrooms were kept clean

Flight Attendants could have been nicer and food portions could be bigger.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

There could have been more options on the entertainment section Nothing was available for non English speaking passengers

great experience. better than all other airlines flying this route.

I didn't have much experience with Cathay Pacific airlines because of delay and missed connections, the bulk of the trip was on Japan Airlines.

Flight delayed first from bad weather, then after boarding there was a problem with the plane. We had to get off and onto another plane...connections were missed and the trip took an additional 10 hours!! Pre-paid seatting was not honored due ro last minute carrier changes. Most of the trip was on Japan Airline.

Vegetarian options should be included with every meal. Even just simple steamed vegetables and whole grains would capture a wide audience.

Flight from Hong Kong to LAX was late, the plane was grubby, overcrowded and hot. I recently flew Starlux and that was a MUCH better experience.

Crew and food were great in-flight. We had a 2 hour delay, no communication, and just got left in a limbo. The crew arrived late and they were running checkouts on the plane (which is important, but why not doing it earlier?) Cathay did nothing to about the delay, and a lot of people missed their connection flights. I had to run and got stuck at checkpoint, which made my entire trip very unpleasant. Got to my gate 5 mins prior to them closing it.

Food , drink experience were great with Cathay. Crew service was excellent. Clean toilet and full snack bars always, pilot took of 26minutes later when boarding at Hong Kong with extra US customs check at gate 9 for US flight, but he managed to arrive only 2 minutes later from flight tracker. Smooth flight .

The experience was efficient, on time, and provided great service.

My flight was suppose to be at 7:45pm to fly but it didnt fly out until 8:55 to dallas so then all of my other flights was late and delay ihad to wait at the airport for extra 14 hours to be able to get on a different plane

Bad food, bad service, cold cabin with no additional blankets when asked for (they told me they don’t provide additional blankets). I’m a frequent traveler and this is one of the worst companies I traveled with (by the way I thought that I booked my ticket with Lufthansa but I didn’t see that the flights were handled by United).

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

The attendant on board was amazing. She should be doing business/first international long haul.

Although our flight was delayed the overall boarding process was very smooth and the crew was accommodating.

I was fully checked in the prior night and i was unchecked and then didn’t have a seat when I boarded. Instead of an aisle seat, I was out in the middle seat of the very last row of the plane.

In overall it was a good experience, the only down point was that the entertainment screen was working properly.

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

I like the pleasantness of how courteous and friendly and helpful everyone is

It was never explained why the departure flight was canceled and delayed for 1.5 hours. It would have been nice to stick with the original itinerary.

Flight was good took off on time arrived early. Crew was awesome and did a great job. Very helpful and courteous. Bags arrived super fast with no hassles. Great flight!!!!!!

A shameful national carrier. Service has gone down from the highs of a decade before. You don’t feel the Filipino hospitality. It’s an aging fleet. Nil comfort, and I flew premium economy.

Many movies do not have captions, which would have been helpful when you have to live with the flight engine noise.

Excellent! All flight related was memorable ! My first experience with Mabuhay Lounge,,, not so good

Everything was fantastic!!!! I can’t wait to fly home 😃!!!!!

Food could of been better. Crew was pretty much average. It was raining a lot on arrival, had to take a bus to immigration building,

Crew excellent calling me by name ! Only downside was no inflight WiFi

I was glad that the plane was not totally full.
