The hygiene of the bathrooms were terrible. Urine smells leaked out into the cabin and the seats were really tight, even for a petite woman like myself. Flight attendants did not go through the cabin enough to offer refreshments.

The hygiene of the bathrooms were terrible. Urine smells leaked out into the cabin and the seats were really tight, even for a petite woman like myself. Flight attendants did not go through the cabin enough to offer refreshments.

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 flight was ok. The person who brings tea and coffee totally forgot about us or just walked past at both meals. And special attention is given if you are Taiwanese

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.

Boarding is fast and easy for economy class, food was ok baggage policies are good

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.

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.

The full flat bed was not that comfortable, hard and lumpy., too much space wasted with those bulky walls and divisions instead of making the bed 3-4 inches wider. The compartment where you put your feet is like a shoebox, poor design. Toilets of A350 are just too small, sink is too small

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

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.

All of the JAL flights in this itinerary were great. However the last leg of my flight from LAX to SFO was through Japan Air’s partner, AA which wqsn’t up to par. We were informed only minutes before boarding time of a delay despite the airlines knowing about the delay far earlier (the aircraft we would be taking arriving arrived and disembarked close to our boarding time, for all to see but AA still kept the original boarding time posted until last minute). Furthermore, once we boarded the taxi/wait time was also extended, with the pilot blaming “construction at SFO” for the delay, rather than taking accountability for the the plane’s late arrival coming into LAX. We took off approximately an hour later than scheduled. It’s for these reasons I adamantly avoid American Airlines when possible. Again, JAL was stellar.

Great service but food taste and options have gone down a few notches.

This airlines is always my favorite. Very consistent customer service and food is good. My last flight with them, I had no idea we landed because it was just that smooth of a land.

Excellent crew, immediate attention for any request. Both ways on time (rather before time arrival at Haneda). Only complaint was that the seats are not reclining like rest of the airlines that I travelled. The Backrest is fixed. The reclining is only within the box seat, so you slide down forward for reclining, not backward. So it was bit uncomfortable. The food for the day trip was excellent. For the night flight, no breakfast was served, only dinner, which was disappointing.

At least it was not very cold inside the plane. I noticed there was now a bidet in the bathroom and that’s good! I didn’t like the window seat. Flight was smooth except for 1 turbulence. Plane was on time. Thanks. Food was not that great. Miso and green tea were good! As usual movies were old and there were no changes.

Food as always. PA was not clear, especially the English ones. Very limited Hollywood movies. Unlike the first flight I had, this plane has less leg room and less room for my under seat baggage.

Please change menu every now & then bc I fly twice within the year and serving the food the same

The Experience was fantastic, it's a quick flight so no entertainment or food. Just a refreshment

Great crew, Japanese domestic flight is just a drink service but crew are very attentive

First of all I had dozed off. And when I woke up, my food was on a tray without telling me the food was there or asking me if I wanted something to drink. They never came back to ask me if I wanted anything to drink and I tried to stop them several times. I personally have a problem swallowing food without something to drink with it. so therefore I could not eat., second thing for the entertainment. There was no place to plug the headset in because the tip had been broken off into the monitor to where you couldn’t even watch a movie or hear any music that was annoying .

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???

Short flight but delayed. Since its a short flight no food or entertainment necessary

We had an awesome flight attendant who came by and made sure we were okay. Checked on us often and even shared some snacks that she had brought on, like edamame with chili and garlic seasoning. Yummy!

Flight was comfortable. The attendants did a great job. I’ve flown on several flights with Hawaiian. No complaints. Suggestion: The egg salad sandwiches seem to be a standard on most flights. I see a lot of them being returned or refused. Seems like a waste. I think Ham & Cheese would be more acceptable.

Overall good experience. I'm just over 6ft with long legs and legroom could be better, but is on par with other airlines. Only real negative was turbulence but that's not the airlines fault.

We were not given the seats we reserved. But helpful attendant at gate gave us very nice seats.

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.

Air Canada had a lot of delays on our flight going back to Seattle. So much inconvenience for a long trip.

Moderate size plane, not completely full, easy boarding, some rows with just 2 seats so a couple can have a row to themselves

The Carry-on luggage that approved by TSA and all other airlines,- always an issue with Air Canada. This is inappropriate as my carry on suitcase meets the requirements however it always asked to check in on AC flight on the gate. Yes I have it for free, but it takes extra time to pick up on the carousel. Apparently it fit the overhead space, so why AC has this issue all the time?

The terminal this flight boarded from was so far away, poorly temperature controlled, and generally uncomfortable. The plane was small but the flight was short, so it wasn't so bad.

Seriously need to improve the time schedule and the plans

Great TV, easy boarding, wonderful ground crew and flight crew.

Pretty good service and US Migratory officers providing services in Canada was awesome, because the arrival was quick and smooth

Rude Customer Service at checkin, 90 minute limit in flight check in is too strict. I was in line for 30 minutes because of slow/insufficient workers. Somewhere I got to the the counter of course the employee warned me about the 90 minutes. People were cutting the lines. No one did anything.

Rouge needs to offer seats with better pitch in economy. Many sick people on a full flight.
