We did not receive our special meal request (vegetarian). The crew was apologetic but then kept interrupting me at least 6 times to ask to see my email or access the web to show verification. (I did not have internet access while on the plane). They kept asking the same questions and taking down the same information. It became exasperating. I understand these errors occur but the constant questioning was disrupted and only compounded the error.

excellent, food was great, the crew were excellent and very accommodating. thank you very much

Older 777 - showing lots of wear - Premium econo seats that are difficult to recline and worn springs to they don't return to takeoff position without standing and pulling them forward

I booked a ANA flight, this was just a regular United flight — as always very bad, dirty, rude service, quite frankly really embarrassing to be flying with this after spending time in Japan.

Staff and crew are wonderful, professional and courteous. Meal is delicious and snacks can be improved. Entertainment needs improvement, pls update selections of movies. I appreciate that our flight was on time

I flew economy class so of course it’s not as roomy as business and first class. But overall it was ok and the seat had an interesting way to recline — the seat itself extended forward instead of the backrest. This way the person sitting behind me would not lose space by my reclining—excellent concept. I wish all airlines used these seats.

Flying with ANA is always a breeze. Seats are very comfortable.

For the price of a seat that is obviously crammed together so as to get many more people onboard and combined with the long flight duration, Free WiFi should be an automatic “Thank You for Flying with Us!” To charge an additional fee when so many other businesses offers it is a bit “cheap” on the airline’s part.

Flight was on time and the crew was as expected, friendly and respectful. Food could’ve been better though.

Food was high quality. Crew was extremely professional, polite, attentive. Flights were on time. Plane had good media tech.

Overall great experience. All four members of my family were seated together without paying extra to reserve seats. Everything was on time. Food was great and healthy. Media entertainment was good. Rock music could be added as a listening choice. No issue with baggages. Flight attendants were friendly and helpful. I would recommend EVA to friends and family.

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

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.

Eva Air's Business Class is pretty decent. With the given price, I think that the food can be better.

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.

It’s wonderful service aboard. Delayed for departure but arrival in Korea went so well.

Ok, the flight was late and the plane was old. The check in crew in Narita were amazing however.

Seems like crew assumed you're korean. Not impressed by crew

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 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.

Extra leg room was nice. The wheelchair situation getting off the plane was a disaster. No wheelchairs or porters were waiting for customers to be picked up when the plane arrive pretty much on time. After about 45 minutes of waiting on the chair service I just walked myself to the luggage claim. Aren't they supposed to know when the planes are going to arrive and land? It was messed up from thr time we landed. No wheelchairs and no porters. Finally After an hour of waiting for them to arrive I walked to the Baggage claim myself. Not a good way to return home from a great Hawaiian vacation.

The flight was so cold from Vegas to Hawaii. Everyone was so cold they put on goodies. They made us buy blankets for $13 each for 4 people. The plane was like an icebox. Now on the way back you made me pay extra so my family can sit together. Will not use you again.

The in flight speakers little touches of humor were entertaining.

The crew was quick and efficient. The flight was uneventful and arrived slightly early.

My seat was broken I couldn’t put it back I have really bad back issues , the flight was 5 hours delayed and there was a drink dude harassing the entire flight

No food or entertainment because it was a short flight. Unfortunately the takeoff was delayed more than an hour

The flight left and arrived on time. the only food offered on the 5+ hour flight was a cheese sandwich. Unlike Alaska Airlines there was no information on the website regarding food at all or any option to purchasse in advance. Otherwise, it was an excellent flight.

Flight was ok, a bit of turbulence, but Ok. With some exceptions, staff could use some attitude improvement. I know they have a tough job, to carry out with little time, I appreciate the control and service they provide. They have to consider passengers medical deficiencies. I for example have eye, disabled.

Parents with kids should all be in the same area. Sounds rude but who what's to fly 6hrs with crying and bratty kids. Just my opinion.

Ok, so I didn’t have seats, so got there very early. I was first in line only to be told, listen for your name for seats. The flight was boarding before they gave me a middle seat, way after others showed up who were given more favorable treatment. Ok, so , don’t show up early and obey all the rules??? Clearly, your gate clerks did not. What gives???

Experienced flight cancelations and delays in 5 days. They seem pretty common to AC. Experienced with one of AC's check-in agents at the counter of a big liar. She lied and acted (yes like acting in a movie) that an early flight was fully booked and refused to rebook me, but my flight was delayed two hours so I could not make my connection. Later, I got help at the gate to switch the early flight (Big thanks to that agent). Ater boading, I found the early flight was only 2/3 full meaning there was almost one vacant seat in a 3-person seater, and multiple empty 3-seaters. AC is wired that it is filled with good and bad employees. BTW, AC employees seem never smile, or they don't know how.

I appreciated the flight was on schedule but the crew told us that the flight would be delayed because of an air craft queue to take off. Instead of us arriving at 11.55pm, we were in Toronto at something past 2am which was a massive disadvantage on my part.

Not much food/snacks. I had just tea and it was so bitter.

My husbands flight last night Vancouver/Sydney was 90 minutes late in leaving. My flight tonight Vancouver/Seattle was also late in departing.

My mother, 80years old, had arranged for wheelchair assist to and from the aircraft cabin and in the airport but, no one showed up for her to de-plane. Apart from Air Canada having a reputation of being late for every leg of its flight so nothing was new this time so this time they did worse by not assisting seniors. I guess our whole family is done with this airline

Flights delayed over 4 hours with no compensation. No agents at counters to assist with re-booking.

Seating for almost 3 hours in the plan before aircraft takeoff. Very exhausted .

The bathroom did not have hand soap. That is unacceptable.

The only problem I encountered was they changed the gate on me while I was sitting down but no one notified me, they had sent me an email and by coincidence I checked it and found out that they had changed my boarding terminal. No one notified me and when I had asked the lady she told me yes this is the spot while they had already changed to another gate/terminal

I was seated next to someone who was, to be polite, not a small person. I had to press myself against the wall as I had no personal space. Aside from that the crew was wonderful and they got me home safely, which is the most important part of my journey. I am very appreciative to your air crews for the job they have, which isn't easy, and appreciative of the fact that they are professional and courteous. The employees I encountered on my journey, with the few exceptions I mentioned in a previous review, are a credit to Air Canada.
