The plane was half empty and I lucky to get three seats to myself allowing me to stretch my legs. Even without that the regular leg space in economy was quite comfortable compared to some other planes in recent memory. Food was fine I’m not vegetarian, but neither of the options offered was. So order vegetarian ahead when checkin in.

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?

First international flight where the meals were not to my taste.

Its fantastic!!I like the food the serve in EVA air😊

Awful had to ask for a supervisor to sit with my flight companion even t booked the tickets together weeks before

I have never heard of EVA air before but I am so happy my wife and I were able to flight on their planes twice. Everything on these flights just felt better than their competitors. As someone with longer legs any bit of extra leg spaces is appreciated. The different options for food and drinks were also a plus. They were extra careful to make sure my wife's eating restrictions were taken care for. They had a before take off and landing announcements on the built in tablets for each seat and it gave out information that was very helpful. Such as what and how to declare your items in the specific country you landed in, any odd items that may be illegal to bring it (and even the reasoning why) and any other information you might need to make your post flight experience better. Oh and the seats were more comfortable, had more ability to lean and the headrest was much better for flight sleeping. The only downside was there were "forced" ads on the tablet at take off for maybe 5-10 minutes but honestly, this flight was the cheapest option and had all the benefits listed above that is such an easy trade off. Im keeping an eye out for EVA air going forward.

Great but I am not sure why I was placed in zone 4 for boarding despite being an Infinity Member??? Can you explain online. Thanks

Plane is new and I was upgraded to first class so all was great.

I was expecting that movie selection and food would have been better. Everything else was great.

Eva is one of the top airlines in Asia... but often are over priced. Finally found a reasonable rate.

When requesting water, make sure, as a passenger, you specify cold or ice added to your cup

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

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 love my Delta crew, they were so welcoming and helpful.

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.

Airline itself is great. While food was being taken off of my tray my beer spilled which was a total accident and I wasn’t upset about that, what was frustrating was I had to ask for towels to clean up and wipe my leg. It would have been left as is if I hadn’t.

Bars and restaurants in Taipei close early. The lounge isn’t very good, but better than the public areas.

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

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.

Rude staff from baggage check to gate crew. Poor instructions. Inconsistent application of baggage rules.

more room in seats, larger snacks, more comms with delays

The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

They did everything right and everything happened right on time.

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Much better than I expected. I had an economy ticket so I was really happy the flight was so comfy and the service so generous. Passengers were all polite too.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

Comfortable economy seats, good food. Didn't like: there was a crying and noisy 2 yr old directly behind me.. finally I found an attendant and asked for ear plugs. That part was good. It would have been better for an attendant to come around with a basket of ear plugs... All in all it was excellent.

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 biggest problem was that I originally had a seat in the first row of premium economy as I had booked months earlier. I checked in and my boarding pass showed the seat in the first row as I had specified. When I got to the gate, the agent took my boarding pass and changed my seat to one in the last row in premium economy against the window. I had specifically booked the first row early for the legroom and for my ability to easily get out and use the restroom when I needed, since I do that quite often. The gate agents explanation was that the food tray on the seat in the first row was not working, so they gave me the seat in the last row. However, when I got on the plane, somebody was sitting in my original seat, and they sat there for the whole 14-hour flight with the tray working perfectly well. I was cheated by someone at the Cathay gate in Hong Kong. It was an outright, unforgivable lie by the gate agent or someone else at Cathay Pacific. I think this is very poor and inexcusable conduct by the people at Cathay Pacific. Perhaps somebody paid the gate agent extra money (bribe)to switch my seat and make it very difficult for me, or something else, but t was a sad experience and a very negative mark on Cathay Pacific.

Good. However the passenger in the search next to mine kept coughing. When we landed in Dallas we had to pick up.bags instead of going strait to the destination (which passengers do in Atlanta)

In between two meals period they're not providing something like banana / cup noodles or bugger. It's really fell sad that I was asking have to wait for 3 hours for second meal. (breakfast)

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 😊

It was good, on time boarding. Have a good service. .

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

Crew was excellent as always. Boarding is a little crazy but manageable. Entertainment could be better and a few more food choices

Flight was on time , flight was great . Crew gave 100% to make sure everyone was comfy. Bags arrived fast . All around great job by everyone.

Crew were decent. For 14+ hour flight, the leg room was cramping, the food is terrible, no flavor, no taste. I wouldn't fly this airline again just dreading about their bland, flavorless food offerings. It was cheap flight, arrived early in jfk but waited > hour to get to the gate. Not sure if that was flight crew's fault or airport fault. But it made me not to fly this airline again

Flight stewards were sometimes short when passengers made requests at the same time. The requests were simple but a smile & a remark of "I'll get to you soon" instead of a curt & passing "Wait a minute." Flying is not cheap & good manners should be a given when taking care of people cramped in seats for longer than ten hours. The food tasted great but doesn't look appetizing. The mid-meal break food or merienda were great in the last two flights I was on.

It was amazing with great service. But the seating could have been better if there was ample arm rest areas

Flight attendants did very well, they were all friendly and very helpful .

Everything is ok except the manner of transporting the people that includes me on a wheelchair. That was my first time cuz I was suffering from “sciatica “ and couldn’t walk well. Upon arrival at LAX it took me almost 3 hrs to get out of the airport bcuz of these wheelchairs procedures. If only I can manage to walk I should have done so OMG. Other than that so far everything is ok. THANK YOU.

Absolutely terrible. I will never fly that airline again. The problem was with the constant emails changing my seats, arrival/ departure times and the aircraft. The staff at the airports and onboard were great. Between making the appointment in May 2025 and my actual trip I had over 50 emails announcing changes. I was traveling with 3 other couples and they experienced the same thing.

My luggages were lost and the service attendant was extremely unprofessional. Despite presenting my luggage claim slips, the attendant stated she had “no record” of my bags and made no meaningful effort to assist. When I explained that the luggage contained our family’s complete scuba diving equipment, her response was dismissive, stating that she “didn’t care.” While lost luggage is frustrating on its own, the lack of professionalism and lack of empathy significantly worsened the situation.

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