Not very comfortable seated in the back plane due to turbulence

We were seated at the back and that was very uncomfortable for me with the turbulence we experienced on our way to Chicago.

Ford not that great the seat not to big for leg room like other airline

It was ok. Not good and not a bad experience

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

Stewardess are nice. Food could have been better and should have a better dessert. They do not offer scotch or beer. You have to ask for it. I also was not happy that you do not serve ginger ale and or cranberry juice. This is my first time that an international flight do not have this. I go home overseas every year and when I travel through ANA, Delta, Qatar, JAL, Asiana Air, United Air. they all serve this two very famous drink. You do not have a great snack tray.

Not accommodating ground staff On board slow service Crew members not very friendly

lunch was good; breakfast was kinda meh cabin temprature was way too high new entertainment system but somewhat limited content

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

Flight was smooth no complaint. Except maybe better food choice for the long flight…

The type of the food requested (Asian vegetarian) was not properly met with. They have very limited snack items that may compensate for the main meals.

The quality of the food is pretty good. Thank you, EVA Air.

Pleasant crew. Very long flight, a bit uncomfortable at times being seated, but not too bad.

No ice for the drinks. Only gave a half a cup of your beverage. Not enough water. I got very dehydrated.

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

My original flight was rescheduled & EVA did a good job rescheduling my flight & connecting flight.

Polite hard working crew. No complaints really. Meals were not to my liking.

Everything was fantastic! The crew really went above and beyond to make it a great flight. I felt cared for with EVA.

One of the flight was delayed. The flight attendant of returning flight to LA was mean.

Staff was excellent. Food could use more variety. -More vegetable options. Menu didn't have juice or soda listed. -The croissants were outstanding!

Asian Vegitarian food was test less No Salt or pepper served Need to improve with Chef who can caters for Peaple from India I am sure Chef knows different varieties of food Indian People like

The flight attendant, where kind of rude, there where hiding for almost 3 hours, without doing rounds to see if people needed water or pickup the water cups, the toilets were full of water cups, because they never come back to pick them up.

Flew on an Airbus 350-900. Excellent aircraft properly cleaned and serviced. Flight crew was excellent plane departed and arrived on time. The A350 has excellent air circulation far better than the 777. I would recommend Asiana to anyone looking to fly in a clean comfortable environment. This is my second round trip flight from New York to Bangkok via Asiana and I will book Asiana again!

Amazing service and fabulous syaff. Loved the jumbo jet too, comfortable.

The entertainment screens are dated and needs to be changed to new screens. Then when we got home, I found out 2 of our luggage’s were damaged (huge) and some items stolen.

I could not choose my seat prior to check in

I had the most wonderful experience from CEB bag drop through deplaning. The staff, the aircraft, food, and cabin crew were all amazing. I want to give a kudos to Marky from Mactan Cebu's Asiana airport staff for his exceptional customer service and assistance.

JetBlue's check-in was great, but there was an in-flight attendant who was very rude and unkind. I didn't realize that the bathrooms were already locked 30 mins prior to landing and needed to use the restroom. Instead of politely asking me to return, she rudely told me, 'NO, bathrooms are locked! Go back to your seat!' The JetBlue flight was more than an hour delay, which made me almost miss my connecting flight with Asiana. I understand the reasoning, but the action they took to get a hold of maintenance was time consuming. It took them more than 30 mins to get a hold of maintenance and for maintenance to get started. The Asiana flight and crew were wonderful, in general. They waited for us who were delayed from the previous flight before they took off and were very kind to take my checked baggage's info. Seats were a little uncomfortable for such long flight, but service and flight attendants were great! However, my 3 checked baggages are missing! They're lost somewhere in the transition. I'm writing this review 3 days after my arrival to the Philippines, and my 3 checked baggages, where my wedding dress is, are all still missing! I and the CEB airport crew have sent multiple emails to both JetBlue and Asiana, and neither has responded to any of our emails. Although, I was able to get in contact with JetBlue's Interline Department who confirmed that the bags were turned over to Asiana without confirmation details.

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.

Great flight, although I flew out of ONT and that is where my car is, lol

Staff is friendly, great variety of entertainment, check in a little messy but due to people not listening. Overall a pleasant experience. Would use again in the future.

3 of the 4 flights had delays despite the weather being fine, but still managed to make all connections

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

Staff were good and nice. There should me 3 meals instead of only 2 and snacks.

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!

Excellent staff made the boarding process fast and easy. Friendly crews on both flights from Saigon to Taipei and Taipei to Los Angeles. Will fly China Airlines again.

Upgrade their seats. They’ve got 20-year-old business class seats in their 777s. The food choices. On the way to Manila and the way back I thought we’re lousy compared to other carriers. The staff was fantastic and very happy.

Not a pleasant experience from the start of booking first flight all the way through to the actually flight. Only saving grace is the food.

No power on an 11 hour flight? What a joke. Crew did not come by enough to get trash or offer water.

Checking in was okay but boarding a little bit slow

There is a problem with the sound while watching movie or listening to the music ( the sound is static & goes on and off). Aside from the sound, the experience was good & stewardesses are nice.

Not leave 12 hours late. This airline is horrible always late does not refund upgrades for cancelled flights inept counter staff.. needs to be shutdown

The food was good but could be better. Also, less salt would be nice.

My biggest concern was with all the schedule changes. Both inbound and outbound flights times were changed, including a time change less than two days before the scheduled departure.

The flight itself was good, however, the disorganization of boarding and the sheer amount of baggage STUFFED into the over head compartments in what appear to be an outdated plane was not okay. The plane was outdated. I walked into the restroom and a panel underneath the sink was on the floor. I called the attention of the stewardess and she quickly put it back into place. The entertainment system had to be rebooted in order to “work,” but even after rebooting, the sound was off. For the amount of money my wife and I paid, we expected a little bit more. Sad to say, but Phillippines Airlines missed the mark on many things going all the way to sectioning off such a small area for all the passengers to wait for boarding. Everyone was on top of each other. They also made you throw away your water, even after the initial security check. So the water you bought after the first security check wasn’t allowed onto the plane, but they didn’t offer a refill station or another place to buy water. Will definitely need to think again about booking with Philippine Airlines.

The charges for overweight luggage were not clear, I think I paid twice, I didn’t argue because I was traveling alone & already felt exhausted.
