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

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.

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.

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

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.

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.

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

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

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!

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.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

8 hours late and the plane smelled like urine, that smell in the morning when your child wet the bed in the night.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

Prior to takeoff, the pilot told us there was a possibility of not being able to land and going to Portland. Well that happened, we took off and then did 8 loops around Spokane before the pilot told us we ran out of fuel and had to go to Portland. So for a 35 minute flight we have now been on the plane for 3 hours (boarded at 6:50 am and landed in Portland at 10:30). Then, we just sat in Portland's airport with no updates of when we can start heading back. All of a sudden, our pilots and crew just left, leaving us stranded in a different city and state. We continued to sit in Portland until we finally got a new crew assigned and boarded the plane (This was from 10:30-2). We then sat on the plane for an additional hour before take off because they had to count us multiple times. We finally landed in Spokane at 3:55 PM. So a flight that should have taken at max an hour took us 10 hours and we missed the majority of the recruiting event we went for.

Good experience and I would fly again with CP. Disappointed that they ran out of the dinner option that I preferred. Other than that, the trip was quite enjoyable.

The crew could have awaken me to eat dinner!! I was so waiting to order the braised duck breast and fell asleep b4 crew got to me to take order. When I awoke, lights were out and food had been served without me eating. I did love the apple juice!

The flight was delayed for over an hour, which made me worry about pets in cargo.

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

Better food quality and suggest using the 777 for the HKG-BOS leg instead of the A330 since the seat pitch seems better on the Boeing.

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

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.

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.

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.

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!!!!!!

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

Boarded the plane last even while I was seated at the back and had to have my bag separate. The same exact special request meal was served as the flight an hour beforehand

Philippine Airlines needs to do better in giving access to wheelchair. My uncle is PWD and they let him walk to boarding. It happened both inbound and outbound flights
