Not very comfortable seated in the back plane due to turbulence

Not very comfortable seated in the back plane due to turbulence

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

Crew was ok, but some passengers were a bit rude. Again, all outlets were not working, only the really slow charging usb plug on the entertainment system. Entertainment system was also bugged, some features just crash, the touch screen wasn't working and when trying to watch a movie the onscreen display kept flashing off and on making it very difficult to watch.

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

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

You did not put me on a Korean Air flight! so I do not have nothing to say

My flight was diverted to Atlanta and I was not given enough time. I paid my travel on April 23, 2023. It was originally Delta from Norfolk to NY, then Korean Air from NY all the way Philippines which is my final stop. Instead from Atlanta to Korea I flew Delta which is okay. Then Korea to Philippines, I flew Asiana Airlines. What I did not like, Ieagle did not sent me an email that my flight was change and so when I went to check in Wednesday the 10th, at 4:30 a.m they told me my flight was delayed at 6;00 p.m and diverted in Atlanta and I am flying Asiana from Korea to Philippines. I do not appreciate that Kayak or Ieagle chenge our flights 5 times and then last minute change again during my day of flight. I hope that you will not make any changes of my flight o Feb 15th because it has to be the same flight with my husband. That is the reason why we made the arrangements early on.

On time. Great service. Good food. Good movies. All good!

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, comfortable, and entertaining. All told, ZERO issues with it. And sadly, so far the flight was WAY more comfortable than the hellhole that is "Lambug Beach Resort" at Badian Beach!

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 would not help with ticket issue since they were purchased through a travel agency. Even though it was EVA ticket stock. Travel agency Budget Air didn't reissue ticket after airline change which I didn’t learn until trying to checkin on Christmas Day and there was no contact number for the agency to help. I will never use Budget Air to purchase flight again and disappointed in EVA’s refusal to help. Thankfully just under 12 hrs before departure someone from the agency was available to reissue tickets. I was starting to think we would not be flying and the stress trying to resolve was completely unacceptable.

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.

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.

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.

Airfare was ok . Food not good , seat ok but not comfortable. Lay over too long , crew was ok Overall just ok

The crew was amazing and really nice. The OS on the entertainment system could use an update, though. It felt old and outdated but had anything you'd need to keep busy. I usually never use it anyways, but that did stand out.

Aside from a LOT of turbulence the flight was perfect! The flight crew was superb and the food was delicious!

2 things that really tanked our experience with this trip with Asiana Airline (which used to be among my favorite airlines): 1) The "random" security screening at the boarding gate is crazily thorough (which is completely redundant to the security screening before we went through the security checkpoint before getting into the gate area), and the water was acquired inside of the gate area (from a lounge operated by the Inchon airport). We were asked to take out *EVERY* single items from the carry-on luggage and open up every comtainers / bags / packages to inspect. To add to it, there were two inspection workers there (one seemed to be a trainee and the other seemed to be a trainer), and the trainer worker held a very unfriendly / arrogant attitude towards us. As the youngest member (a minor) of my family was being "screened", the rest of my family wanted to make sure that no inappropriate actions would happen to her. That trainer worker yelled at us and attempted to use rude body language (waving her hands) and facial expression to ask us to stay away. 2) The luggage handling at the destination was really *REALLY* bad. Among my 25+ years of travel experiences, I'm going to have to say that this was the worst luggage experience where we didn't lose our luggage. Our flight was scheduled to land 12:45pm, and landed around 1pm. 15mins delay in landing is absolutely normal. Deplane process took a bit longer than usual flight (we waited for around 20mins, after arriving at the gate, before people were able to actually leave the plane). However, the luggage took another *2 HOURS* to arrive at the baggage claim carousel. This is insane. What's worse is, due to the delay in luggage, the flurry of passengers from our flight collided with 3 other incoming flights. The US border / custom line was like the longest Disneyland attraction line winding through the entire arrival hall and around all the baggage claim carousels (like at least a thousand people). I've never seen anything like that at SeaTec airport (US border control), period. The luggage claim experience really tanked our trust and overall impression for Asiana Airline's Seattle airport ground operational effectiveness and efficiency. This has to change in order for them to remain relevant / in-business with increased competitions from Korean Air and other Asia-based airlines.

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

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.

The crews are professional and nice, the flight was on time

Food - while flying in Japanese style was edible, returning options were not edible to me

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

It was good no problems made it on time for the next flight overseas!

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

The crew was fantastic and the over flight was perfect as well.

They shld provide food. Between food they are giving 10 hours gap which is toooo much

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

I had already opted for Vegan food before 2 months yet they say we have no record for it,
