Customer service in Hanoi needs work, outside of that, everything was good.

Premium economy seats that I paid extra are not worthed.there was not much difference from the regular economy seats yet I paid alot more for it Disappointed

The food was amazing good especially for evonoply. The seats were comfy more then usually..crew was very nice and helpful.

amazing and great food. everything was smooth from start to finished

love this boutique luxury airline. crew was nice and attentive. Lounge is too small , i think they should have more area for relaxing and lounging not just to sit and eat .. feels like a cafeteria more than a lounge. overall i enjoy it. food on the plane LAX to Teipei should inprove a bit. no flavor and more drinks pls

The overall experience with STARLUX was phenomenal. One of the best highlights for me was the smooth landing in LA(smoothest landing I’ve experienced ever) and the attentiveness of all your staff from check-in to boarding. Also, flight left and landed between airports on time. I highly recommend Starlux to my family and friends and I’m excited to fly with you again.

We are scare because almost missing the fligh from Seattle to San Diego ! Starlux not have enough members for servicing with wheel chairs? We almost left behind , so we must walking !?

We are on economy premium but they put us in economy seating? Asking why the fligh supports said : If you not happy you can claim for refund?

I liked everything but I flew business class and StarLux booked another passenger and a one year old , in business class The child cried 80 percent of the flight, the flight was a long 13 hour flight. I’m 75 and I have 10 grand children, I love kids But with that said it still made it not and enjoyable flight. Ask your great flight attendance what they think of the situation, they had to deal with. Let me know what they said Respectfully, Al Eaddy

Everything is smooth. Very good. Except flight arrived SFO 30min late.

Other than spotty internet, great servic, comfortable and smooth flight!

Crew was good. Sometimes food was eh. The spaghetti is gross for me. First time i got food, they didn’t provide utensils so i ate with my hands. I was hungry. They gave it to me 20 mins later when a crew member came by. I would fly with them again. Nobody is perfect

Eva air was fine - Trip.com via KAYAK sold my family access to a “VIP” lounge fo a layover in Taipei… i’m please look at my pictures. It was a scam, Trip.com knows it and they are perpetrating a fraud through your web site.

My flight was amazing smooth and the attendants were so friendly and nice

Organized boarding process, superb food, lovely crew, even arrived early!

Crew are excellent. Food was good generally. Seats are small and there isn’t much leg room. Overhead bins are very small.

What could have been better, was we were delayed from takeoff for two hours. Initially we were informed that we were delayed for refueling. Then we taxied out on the tarmac, then just waited there for a long time, with no explanation of the delay. Were we just waiting on takeoff clearance or was there some other reason for the delay? The pilot, nor none of the crew informed us passengers. That was not good customer service. That needs to be improved, whenever a delay, inform the passengers for the reason.

More new and classic movies in English. Boarding was a bit chaotic. Nore, clearer information during boarding to customers.

More seat space More bathrooms Charging outlets Plane was old

This flight was long and I am so thankful I had a seat in the back of the plane. As I usually must get up and stretch every hour . The crew were probably the most friendly I have flown with. Thanks and I will book again with Eva air. Food was ok too.

The crew were professional and attentive. Blankets and pillows were on each seat which was appreciated. The food was served warm and had a balance of various nutritional options. As far as the monitor there were not enough English speaking choices and foreign shows did not offer English captions.

We really enjoyed our flight to Seattle. The food was great and service was attentive.

Everything was fine except the seats were quite compressed and hard for the 12 hour flight

The crew are amazing. Very professional, polite, kind, and accommodating.

Well, we upgraded and on a 14 hour flight not sure how we would tolerate it otherwise. The upgrades are ridiculously expensive and even with empty seats even in first class it was difficult to upgrade. Probably won’t fly China Air again due to this. The attendants tho were much better than the airlines in the states and there attentiveness and care for your comfort far exceeds other airlines in the states.

Flight attendants. Food, entertainment and most of all, be on time.

Very bad. They don’t allow group people to sit together by blocking most of seats and opening only single seat during online checking in. . By doing so, they can rip off customers at the check-in counter by collecting extra money if we want to sit together in the same row.

Hour late but understandable under the conditions. Taoyuan airport could have clearer signs language wise and more staff to help direct people.

The flat bed full lying position is not comfortable at all, this could be improved, it is at an awkward position which i dont have the same issues with other airlines business class.

The flight was uneventful and the crew was kind and professional. Really appreciate the option to order a vegan meal for the flight!

Food isn’t hot, seat is too tight even for a person weight 120 lbs.

The service was better on this flight from the long haul one, but still very poor from The Cathay Pacific of the past.

Seat is too small. Food selection is limited and often ran out of selectable item.

The go to HK trip will easily giving jetlag, but coming back to Chicago has no jetlag because of the time taking off matter.

For an international flight, the service was average at best. It could have been significantly better, particularly with regard to the food quality and options. Additionally, having only two restrooms available for the entire Economy Class made the experience less comfortable and resulted in long wait times.

The staff from beginning to end we're friendly and helpful. The food and beverages were quite good (but see the comment below). I also liked their entertainment options, as we'll as their frequent attention to the airplane restrooms. Here are the reasons this is not a 5-star review: - You have to pay for WiFi on the plane unless you have some level of seat upgrade. - CP sent me a warning that the name I entered to book didn't match my passport. True, but the form for entering my name didn't allow for anything but a middle initial. This lead to a lot of chats, phone calls and stress before finding out at the ticket counter that it didn't matter. CP has modified their notice to now tell you this key bit of info. - After consuming a chicken dinner they offered (Kathmandu to Hong Kong), I developed symptoms entirely consistent with salmonella, beginning about 6 hours later. There were some odd things about the serving of this meal, too. Our row was the last one served, and we were given a tray without the entree on it. About 10 minutes later the stewardess came by and said they only had one chicken meal left. My seat mate and I decided he would have the lamb and I would take the chicken. I think I lost. I suspect that this entree was left over from an earlier flight and they were scrambling to get the last row fed. My seat mate and I were the last two to receive our entrees. I am not accusing CP of giving me a contaminated meal - just that the onset and progress of symptoms closely match those of salmonella poisoning. I opted out of the first meal on the next flight 13 hours later, but was fine after that.

Good good, good seat, good entertainment system. Customer service is good but can be more polished if CX charges a premium price.

Frequent Flyer number should.have been put in at time of booking.

I do not think there was much that could have been done to make it better. The delayed flight was due to bad weather. The turbulent patches were very unavoidable. Am simply thankful that there were no sudden and / or sharp drops during the flight. I do extend my compliments to captain Marcus I believe was his name and the rest of the crew. They all did an excellent job. My only question is whether I get a refund since the seats I had chosen and paid for were reassigned.

I spent 45 minutes with supervisor trying to get 2 bags checked for this international flight . He wouldn’t give it to me because West Jet was involved in this booking.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Service was professional and quick. Premium economy seat was comfortable given the class

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Crew was great! Good meals. Had room to stretch out

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

Uncomfortable plastic seats even in premium economy. No free wifi. Even paid wifi was spotty to nonexistent. Bad food. Much worse than economy on foreign carriers like Qantas.
