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.

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.

Great experience, comfort and food is delicious. Always great service and one time

The food from Los Angeles to Taipei made me throw up. The flight is also not comfort. But the staffs are very friendly and nice.

Aircraft was late getting to the gate - probably due to weather. We left the gate one hour late and had to wait another hour since we lost our slot in the takeoff queue. Our box was very wet and was falling apart when we got to Clark. It appears that luggage was exposed to weather in TPE while waiting to be loaded. Crew, however, handled the delay well and was able to provide planned service.

For the price, it was better than other airlines; quality of food and service was very good.

I appreciate the email reminders for online check-in which made my entry to the lines less stressful. The flight was on schedule and on time. The baording staff were proactively helpful and approachable. The airplane inflight food, entertainment and comfies as well as provisions are excellent even in the economy seating. The airline transfer was smooth and easy! Luggage safe and intact! Thank you EVA airline for making my trip a reliable safe and comfortable experience.

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

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.

Crew's attitude can be better. I asked one crew member to help to put carry on baggage into overhead bin, but he was not willing to help. I needed help because my height is short. His attitude was bad.

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

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.

Paid a premium a have a shorter transit time in Hong Kong, but Cathay pacific rebooked me and ended up waiting for 10 hrs in Hong Hong airport.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

As before, my only problem was not being able to download my boarding passes prior to arrival at the airport. Everything else was perfect.

The only problem I had was not being able to download my boarding passes prior to arriving at the airport. Everything else was perfect.

Better. I took an aisle seat this time. Although the overheard compartment above the seat ahead of me kept opening up during flight.

If I had blood clots, that window seat would've killed me for certain.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

I had no checked baggage but was required to hand over carry on baggage at the door of the plane. There was a lot of overboard space in the plane and I was one of the last ones. I ran to get my carry on but it was gone. I was given back at the plane door in Toronto, so the wait was not as long as it would have been at the carousel.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

I flew with my dog and had already purchased my dog’s ticket. Even that morning I had called costumer service to insure that my husband and I had seats together since the website was giving me an error when choosing our seats and the representative mentioned our dog. I showed up early to the airport and when I got to the gate and we started boarding I was help back and told that I was supposed to have a yellow tag and that I should have checked in at the counter for them to give me that tag. I was not aware of this, the representative on the phone did not say anything. Nor did I see it anywhere in the checking process online, so if you travel with a pet and are not checking in luggage, just know that you still have to go to the check in counter when arriving at the airport unless you want to be the last one to board and not have room for your carry on in the overhead bins. Other than that, I had a great experience.

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

We had a layover from YVR to Denver. We bought 4 bottles of Absolut Vodka at the YVR Duty Free for $116.20, after going through security and American Customs Pre Clearance at YVR, Vancouver. When we landed in Denver, United put us behind the American Customs as well as TSA again for some reason. We were forced to go through American Customs and TSA again. TSA confiscated our rightfully owned Duty Free Absolut Vodka bottles. Because United incorrectly forced our flight behind American border and TSA again, we missed the connecting flight. After United put us on a later flight, we eventually arrived in Chicago very late, with hardly any sleep. I am looking for compensation from United for our incorrectly confiscated Absolut Vodka bottles worth $116.20, as well as compensation for incorrectly putting us behind American Customs and TSA again, causing us to miss our connecting flight, making us arrive extremely late in Chicago.

From the first moment you interact with United Airlines, you can expect nothing less but extreme frustration. The baggage handler at the bag drop seems completely unbothered by the presence of customers waiting in line. No help was extended to load the baggage whatsoever. And if any of your bags is overweight by 0.01 pound they will make you re-distribute everything in your suitcase just to play power trip. When it was time to board no help was extended to customers to locate their seats. Moreover. It was a chaotic mess at the gate when it was unclear who should board first and everyone just bunched up, trying to get on the plane. I am sure the crew was doing their best to perform their jobs while being paid their wages however it shouldn’t be that hard to smile once or twice when you’re in the business if serving customers. It is a shame for the United States of America to have a flagship carrier of such low caliber. Our flight was also delayed by about an hour and a half due to further delays prior to our inbound flight. Being someone who has travelled for both business and leisure in Asia, Europe, and South America I have never experienced such poor quality of service.

Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

It is clear that someone knew, and competent, is in charge of food at United Airlines at least for the international flights. I was flying in coach, but the choices of the dinner were excellent. Tasty, and appropriate size. I had the beef, which was a little bit like a shepherds pie, and it was good. Nothing comparable has been served on a United flight in years. It will not be confused with three star food, but it is very good for airline food. Even better was the breakfast choice between a cinnamon roll and a breakfast sandwich. I chose the breakfast sandwich which was absolutely delicious and which I would happily order again at my local Starbucks or Panera. It is clear that someone knew indifferent is in charge of the food and it’s about time.

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

I was glad that the plane was not totally full.

The flight was fantastic and the crew was absolutely excellent, but the entertainment system on the B777 was not working. That's a long time to spend with no electronics. The crew offered I-Pads but I had brought my own. I am only pointing this out because this is the second flight on Philippines Air where the entertainment system was down. FJM

The checking in agent tried to give me a different seat. She tried to give me an economy seat even though I had already checked in with a seat assigned and paid an extra $300 for those seats. She also separated our seating assignment. Very unprofessional and seriously a bad example for an agent. She was rude when I showed her my receipts and she made us wait more than 15 minutes before we were able to get the right boarding passes and correct seats (seats that we paid for in advance)!!!

Terrible check in and food was like from fast food

Delayed, from morning flight, they moved to evening. And said, their earlier flight is already full but we can upgrade the seat

Manila airport is a dump. Very dirty and not comfortable at all

I thought the meals and meal choices were excellent. The cabin staff was helpful and as is the norm for Pinays, extraordinarily empathetic.

Nice new lay-flat seats in Business Class!! What a wonderful experience!

Well it's strange everytime going the flight is late coming back the service is superior
