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.

I wish the serve should leach and drink. Maybe because only 2hr

It was ok I thought because my flight was 1pm i was expecting to have lunch but it didn’t and after 7 hr finally dinner time was only chicken sandwich and next breakfast was an hour before plane land in Tokyo. so I should bring some food with me. Japanese flight attend was nice but the other was chewing gum and how she ask and respond to customers was not professional I felt. Maybe because Japan flight attendant is highly train and everyone looked very dress and professional so I was kind disappointed. I like that the bathroom was very clean .

Lovely airport at Haneda. Great food selection. Spacious and private boarding area with dedicated bathroom for each gate.

They did not get my request for veg food that i made a month ago. Also did not have any backup veg food on board or fruit plate or simething. Very disappointing as i had hward about how grwat ANA was supossed to be. Alsio entertainment was lacking and screen and tech was subpar. Overall just mid to low tie. They are living off reputation and are being passed up by most other carriers.

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.

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

t and I Flight crew did excellent job taking care of us and feeding us and staying professional. The boarding was delayed by an hour and then extra security measures were taken. No real explanation except for they said it was more of a maintenance dey

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.

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.

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.

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.

Food and roominess were better on other international flights I’ve been on.

This flight was delayed approximately 4 hours due to bad weather in HNL.

The flight was cold. The entire time, the food was nothing more than a cheese hot pocket. They wanted to sell everything else midway during the flight. They said that we were landing in a half hour and then added that we had to return to Honolulu, but gave no reason why. I was so scared I was crying. I didn’t know until we landed that it was because of an unruly passenger that we had to turn around. The crew was very cold about it, and we had to wait in the airport where they gave us snacks, which was nothing more than a bag of pretzels and a fruit juice

It was great with the exception of a rude desk member on the way back. And a terrible sandwich on the way back.

One of the best flights Ive had in a long time

Flight delayed then cancelled then gate changed two times then baggage lost.

My flight was canceled minutes before boarding started. It took three hours to get rebooked and it was on another airline overnight with another stop added. All I got was two $15 food coupons.

The plane is extremely loud and there’s no place to charge devices.

Not great to be very honest. Our flight was delayed after we sat at the airport until 15 minutes after we were supposed to leave . We were then notified the plane was being worked on “and the parts were out in the ground and still not finished .” Even though the work started the evening before and they knew it wasn’t fixed. . Then we were told it would be a 1:15 pm boarding time so we waited then at 1:45pm we were told it would be an 11:15pm boarding . It was changed to and 3:55am boarding the next morning . We lost out on a day in Hawaii and a night of our VRBO rental.

Safety record impeccable and important since flying many hours and thousands of miles over ocean.

Limited snack options cause the snack vendor was on strike

The experience was generally above average. The only downside was the absence of WiFi during my flight from Vancouver to San Francisco.

I was appalled to have to pay for just a regular seat when I went to book 24 hrs before my flight! Because it was only an hour flight I didn’t choose a seat from Grand Junction to Denver, but I did for Toronto and had to pay just to choose a regular available seat! In my 60+ years of flying this was the first time I have heard of this. Also, allowing people to bring on “huge “ suitcases, not carry on size, but much bigger, and then a large pack pack stuffed. So they take up all the room in the overhead bins and if we are later boarding, there is no room so we have to check our small carry on. I have already paid for and checked in one bag! I certainly will not choose to fly with United again unless it is the “only” airline available!

on demand entertainment in seat back awesome Check in Kiosk too demanding with endless demand for more information information then says go to counter. Counter agent unfriendly. Do it yourself check in luggage procedure not intuitive, upset employees frustrated the whole procedure.

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

Crowded plane but it flew on time and had friendly staff

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.
