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.
Very smooth flight. Superb crew, great food and service. Slept most of the way. Excellent airline.
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.
EVA air was nice. It was the first time I’ve flown with them. The poor entertainment choices for 2 long flights will make me think about choosing them next time. I didn’t know if would effect me so much but I couldn’t sleep and it added to the stress. The food was terrible for me but I couldn’t find how to inform them about my diet when I bought my ticket.
Boarding was good. It will be nice to have beer anytime. I asked for a beer at tea time & I was refused. Quite disappointed
It was a good flight. I would highly recommend it to family and friends.
The employees were professional and efficient. I consider myself a traveler but have trouble with the international fare served on airplanes. I admit Americans buy their food in the supermarket and we typically don’t eat the ligaments and cartilage. I know that is whiny but as I age, I dislike it more. At least things weren’t covered in cheese. The desserts are terrible! My neighbor didn’t eat her bread so I asked if I could have it. First time for everything but had been traveling a total of 27 hours and was hungry.
The night flight was only 2/3 full, which is always a plus. Room to stretch out for sleeping. Gracious stewardesses, attentive, and slim/attractive (which is rare these days). Good food, and curtesy wine.with meals. Comfortable seats and decent leg room (economy class)
Not great, will likely try to fly another or maybe I should have upgraded my ticket? Needed Air…
I don’t think I’ll be flying them again. Tight seats, no flowing air or air nozzles that you can turn air on you, for those who could have motion sickness this would be your worst nightmare. The pilot was great and experienced (which is what you want when flying 12 hours) overall I’m thankful knowledgeable pilots!
My ticket did not indication which group I was in for boarding; the gate attended help me
Very routh cabin crew food is only 2 meals for 13 hours fry with them They should get better training how to service good super routh language and talking with customer
When I booked a premium economy ticket. I then had to pay $100+ to book my seat.
Didn't like on this return inbound flights (from Hong Kong to Vancouver) Outbound to the Hong Kong was good.
I was ordered vegetarian food, but didn't services to me :(
I did not take the flight, tried to cancel it right after I booked it, but was unable to reach anyone. I blame Kayak for this situation because they sent the booking through another company and I was unable to get anyone to talk to me about the situation. I had to just take the hit and pay for another flight through Cathay Pacific, which was wonderful. I will never use Kayak again. (I bet they don’t post this review!) I’ll just post about them on social media sites. I don’t want anyone to have to go through the hassle and expense I dealt with.
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.
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.
Worst experience I have ever had with any airline in over 25 years.
very professional and very attentive to my Special Needs as I required a Wheel Chair and assistance to board
Crew was great. But a bit understaffed. The business class seat, etc were dated. But comfortable. Some legs had entertainment system from a decade ago. Selections were rather poor. Food was mediocre at best. Actually poor for business class standards. I liked the lounge in Hong Kong. Showers were great. Food was nice.
Very noisy and careless crew on this overnight flight. They should understand customers want to sleep
Everything was fine and I have no complaints or things to note.
Highly impressive. On time. Smooth and fast boarding and disembarkment. Really great service
The economy seats are much indeed roomier. Meals needs improvement.
It was okay overall but the food was very, very bad.
Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍
Compared with other carriers business class for an overnight was not worth the extra expense.
Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)
Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.
AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.
For an 8.5 hour flight the service on board lacked a bit. Service start was slow, the food was worse than usual and they skipped the snack they were supposed to deliver before landing.
Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.
It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined
Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.
Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good
Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.
Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers
No Charging ports for personal electronics, which were required to use wifi entertainment.
They are a great airline, and i enjoying flying with them. However my experience with booking through Kayak was a horrible experience. With all the restrictions and glitches of website. My entire bookings by kayak was wrong. And there was no possible way of fixing anything with them, because they hand over responsibility to the airline after purchase is made. Will not be booking through Kayak again and will inform my family and friends not to as well.
I liked nothing about this flight nor the incredible lack of service and communication on this flight from the Captain to every staff member. Arrogant, entitled and lacking any kind of basic customer service
I booked my flight ni November and was placed on standby? How does this happen. Flight was 1 1/2 hours late departure plane was switched to a smaller plane easy to tell this is a government run company they don’t care about anyone
Plane was old, cabin was small, overhead bins were small, seats really uncomfortable, no seat-back entertainment
Excellent crew, great food despite catering issues. We need more people like this.
1. The PA system was painfully loud. 2. Overhead bin #33 was missing—I find this troubling.
I had a disappointing experience at the San Diego airport with one of your gate agents. Despite being in Zone 4 and traveling with a standard carry-on bag that has never been an issue (30 flights in Q4 alone), the tall, blonde gentleman forced me to gate-check my bag. When I politely asked if we could verify the bag’s size, he became confrontational, even threatening to deny me boarding twice. His behavior appeared erratic and unprofessional, projecting a negative attitude onto passengers, as if he was going through something mentally. Notably, there was ample overhead space once all passengers had boarded. In contrast, the tall, older Asian agent handled the situation with professionalism and calmness, making a clear effort to de-escalate. As an avid traveler, this unnecessary inconvenience set a frustrating tone for my trip to Asia.
