Picked our seats when we purchased this flight (2 seats alone on the right) but were assigned two middle seats in the middle row at the gate. Very disappointing for a 10 hour+ flight, and what is the point of picking and paying for seats ahead of time when they just reassign us?

Picked our seats when we purchased this flight (2 seats alone on the right) but were assigned two middle seats in the middle row at the gate. Very disappointing for a 10 hour+ flight, and what is the point of picking and paying for seats ahead of time when they just reassign us?

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

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

More seat space More bathrooms Charging outlets Plane was old

It was a pleasure to fly with EVA airlines from Taipei to San Francisco.

Great service. Was there a food option? I was given food (I could have ordered ahead of time?) but had no choice. I like choice.

Everything was excellent service was good.Only one problem my trip san francisco to tapie was good but the Taipe to HongKong we change gate 3times a lot of walking n everyone has to rush around from gate to gate.By the time to board our flight i felt soo sick from running from one gate to another.That was the only problem i face

A wonderful new plane. Great menu. Professional service. You and your wife were completely satisfied.

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

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.

I absolutely loved my flight from Taipei to LAX. I was originally assigned to a different seat, however one of the stewardess noticed I was uncomfortable in my seat. She offered to move me to a more comfortable setting. Although she didn’t have to do what she did, I am more than grateful and thankful for her doing so. My longer flight felt much more comfortable, just by her taking notice. I really appreciate her.

The flight who provided services on my row had some not-nice attitude and not smiling at all.

Very good , the weather was terrible, but i admired the professionality and politeness and care from the crew, and the excellent contition of the plane

Comfort was left wanting due to such a long flight, made the wife and I wish we could upgrade the seats to Business class or First Class, but did not have that option. Food was good but had very limited options and I have a dietary restriction which was difficult for the staff to accommodate since everything provided came with cheese on it. (Cheese could potentially kill me) Did not have an option to inform the staff until we were already in the air about the restriction and was not provided another option before flight departed.

The plane was uncomfortable. I paid extra for more legroom but the seat was still uncomfortable. Other seats on the same exact row didn’t have to pay extra but still have extra legroom. I didn’t understand why I needed to pay $170 for. It was Iike China airline just wants to make money off their passengers. It was unfair.

Free Wi-Fi could have been better in the Airport.

Baggage made it successfully to destination despite short layover. Appreciate that.

Flight was delay almost 2 hours from Hong Kong to Taipei. Last minute gate change from 24 to 66. Long way walk. We need to run in the Taipei airport to catch our next flight from Taipei to Vancouver. That is so suck!

The bathroom is disgustingly dirty. It looks like the crew members didn’t clean it on a regular basis. Also, who made the bathroom so small?. I am not a big girl but I still feel very cramped inside. Def unpleasant experience to use the bathroom.

dropped my bags at Seattle Delta curbside. 1.5 hours before departure. one bag oversized made it. the other was left at curb and mishandled. poor communication from delta in sjc baggage claim. No internet on flight and food choices in business are horrible. You are forcing us to fly Alaska which is shockingly better than the Delta experience. that is a low bar.

attendents were rude and the boarding was disjointed and poor

There was an incredibly surly flight attendant that ruined the experience

After boarding the plane had to wait an hour at the for the copilot to show up before we could depart

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

I'm 6' 2" and even in economy plenty of leg room

great! appreciated the last minute upgrade to Comfort+ exit row, as well

My seat was changed without my consent. It wasn’t a major deal but annoying.

worst experience ever, they cancelled my very long 2 flight 20hours+flying time trip 8 hours before departure. The only options given were change of dates. the customer line was the worst with a wait of around 30 minutes each time you called to talk to an agent who couldnt help much anyways. :eft me scrambling to cancel and book an entirely new itinerary with other airlines. Worst ever and will not consider Cathay pacific anytime in the future

The crew are timely, friendly and professional. I was very impressed.

They overbooked the flight and reassigned my seat. To add insult they lied that my assigned seat was broken and promptly gave it to someone else

Jain veg meal I opted was super in taste but there was no sweet/desserts with it. I was a big missing in the meal...Please add some sweets to end the meal with 😊

The meat-and-rice combination was a good idea, but the food could use some improvement. The meat looked a bit mushy and almost like ground meat, which wasn’t very appetizing, and the flavor was just average. Other than that, everything else was great.

My boarding experience was so bad. While traveling from LA to HYD, the boarding was smooth. But the boarding experience from Hyderabad to LA was utterly poor and unprofessional and caused lot of anxiety and stress. Even though we were at the airport Boarding well in advance to accommodate for Immigration and Security Check, Cathay Pacific Boarding On Ground Crew has done a very unprofessional job. It is one thing to follow rules, but being inconsistent and not being able to communicate this clearly is wrong. I was not aware that my laptops weight in my backpacks is also counted against the cabin baggage. While coming from LA to HYD, the ground boarding crew didnt ask for this. They just checked the Cabin bags weight. But at HYD, not for everyone, but for some people they enforced this. Our Checkin Luggage was carefully weighed at home and was accurately measured to 23 kg, Now they asked to move all the weight in our Backpacks where most of the weight is from Laptops and tablets for each family member, I need to accommodate this ~10kg from 6 laptops in to one of the suit cases and pay extra for excess baggage at the airport boarding place. Without a weighing scale how can I accurately move all the items from cabin baggage to one of the suitcase. D Venkatesh is the guy who enforced this. But I dont have a problem with the rule enforcement, but the way he guided us in solving the problem. I was willing to pay the extra money for the extra weight. He told me that the 32 kg excess baggage is allowed with 150 USD. I understood that 32 kg is extra on top of the 23 kg chickin baggage. SO I pushed all of them to one suit case and then when I took this suitcase, I was sent back saying that he meant the total as 32kg but not the excess should be 32 kg, I had to go out of the line make these changes without a scale thrice like this. They literally harassed me. Noushad his manager was sneering at us. When I said, I am going to complain about this, my wife heard him saying some bad words in Hindi. You get one chance to harass your customer. I will never board Cathay Pacific again.

I’ve flown 2 better Asian airlines in the past year.

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

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.

The worst experience ever! Lots of flight delays and rerouting that ended up doubling the total time. . I had to recheck my luggage because I was rerouted to Tokyo and ended up on ANA flight. I missed connecting flight twice because of the delay at Cathy Pacific. Additional stop added, rerouted to a different country for connecting flight and ended up in long waits and delays.

Terrible flight attendant. Rushing me as I ate my salad and appetizer. Served my dinner while I was still eating my salad. My dinner was dry and very salty. He asked me what I wanted to drink, I said flavored sparkling water. He said we don’t have that we have plain sparkling water. I’ve flown United many times and I know exactly what they have. 10 minutes later he asked me what flavor sparkling water I wanted. Did this with an attitude as if he was being bothered!

Starlink internet made the flight time shrink and I was able to work.

The plane was so old. I paid a ridiculous amount to fly business and there was no internet for six hours! This can't be happening in 2026 and especially in cross country flights where there are a high volume of business travelers.

The food could have been better and the entertainment could have better movies or streaming.

Connection times always good online, but not in reality when first leg is delayed (2 out of 2 times this trip).

This is the flight that I was not able to upgrade. Airplane had more empty seats than full.

Flight attendants were friendly & good service, food sucks, seats uncomfortable, not many Asian movies or shows flying from Hong Kong

I needed to make changes to my flights. When I called customer service, they assisted me with care professionalism.

I found that it seems that the space for personal bags or luggage is not enough( the cabinets for personal bags or luggage over the seats) .

The service was non existent . Crew did very little didn’t even answer call button . Premium economy in this long haul was the worst I have ever experienced . Never again flying with them .
