seats are pitched well. you don't feel too tight.

I appreciate the email reminders for online check-in which made my entry to the lines less stressful. The flight was on schedule and on time. The baording staff were proactively helpful and approachable. The airplane inflight food, entertainment and comfies as well as provisions are excellent even in the economy seating. The airline transfer was smooth and easy! Luggage safe and intact! Thank you EVA airline for making my trip a reliable safe and comfortable experience.

Movie selection was not as good as recent flights I've taken (EVA and other airlines).

Very smooth flight. Superb crew, great food and service. Slept most of the way. Excellent airline.

The boarding was organized and efficient. The crew was very thoughtful and did not wake me up when meals were served. I was totally exhausted after 2 weeks of vacation with a tour group. So sleep was more important to me. The crew just left me a sticker telling me that food had been served and if I woke up hungry to contact the crew. I did have the last meal scheduled on board. Food was very mediocre. The scrambled egg and minced meat were too salty. The porridge was passable. I was disappointed because I have high expectations of food from Taiwan. I thought EVA being a Taiwan based airline would have served its customers better tasting food.

The food is quite mediocre. I had spaghetti and the tomato based sauce was quite salty and there were no other flavors, no spices used in the sauce.

basic and only minimum of service, they offer nothing special

friendly and professional cabin staff... seems cold and a bit aloof...

delayed and the cabin crew was like trainees.. a bit careless and not so pleasing to their job

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The boarding process for Korean airlines is very straightforward and easy. You've never met such helpful and friendly people. The food was great and the entertainment options were excellent too. My teenage boys found programs they wanted to watch while I had fun watching a full season of the Last Man - the Blind Investigator (Japanese), which my wife enjoyed too. My only complaint was that it takes a very long time to taxi at ICN (20 minutes) and the pilot had to hold at the gate for 10 minutes after our scheduled departure time, which meant we got to Seattle 27 minutes late. Luckily I had a long enough connection to make my next flight, but just barely.

The food on this flight from NRT to ICN was average. The staff were very friendly, but the flight took about 60 minutes longer than it should have because the pilot was only flying at 330mph instead of 500-550. Not sure what the reason is for that, but it meant for a much longer flight.

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

My second flight wasn't better than the first one. And this is 14 hours trip, crew came out only to offer food and the choices was poor. This food choices are good for Asian people but not for westerners. The breakfast kind thing was a corn sausage really disgusting. The air-conditioned blower really blow high and cold, turn out on my arrival to feel seek, that makes the trip uncomfortable. The crew didn't not really come out during the trip to offer drinks or snacks. No fruits available. Very poor service

Food choice could be better, plus the crew can walk around and offer snacks and drinks. Also the air-conditioning onboard blows high speed, and very cold makes the trip uncomfortable.

long flights are difficult but the crew and amenities made it a very good experience

Our seat row plus one ahead and behind we're completely overlooked during beverage service...

Always have great flight experience on Korean Air. Glad to have been able to book this on Kayak/Under Pricer this year!!

I loved everything, I was just a little confused on my bag allowance. When I checked in it said I was allowed 2 check in bags, but when I got there they said I was only allowed 1 so I had to pay an additional 200 dollars! Other then that everything was great! I would love to use your Airlines again when I fly out to Manila again in late May, however I want to be able to have 2 bags included this time lol 😆

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

Everything was fine and I have no complaints or things to note.

Overall, it was ok. However, the food was very sub-par.

The economy seats are much indeed roomier. Meals needs improvement.

Horrible airline. Missed my baggage and don’t want to reimburse for the basis items. Pathetic customer service

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

bad… no veg food was provided eventhough i pre ordered special meal

no veg food was provided eventhough i pre ordered special meal

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

My suitcase was completed destroyed. The top part is broken and unusable now.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

All male crew was just too woke for me. I felt like a sardine. I will never take a window seat or the rearmost seat again. I booked early and did not pay for seat selection and that was a mistake. The security at IAH was atrocious. I was violated and radiated as I was in a hurry to connect to my other flight. I may have lost items under the seat in front of me that I couldn't see nor bend over to look.

Liked nothing. As per previous segment it was delay delay delay.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

Most disapointing experience. We were rerouted to Toronto, after a 7 hours flight , where we sat on the tarmac for a little over 4 hours, in a full airplain with no air. We were given a tiny cup of water twice during that wait. After the long wait we taxi out of toronto to wait another 30 min. Many people missed their conections including my kids and I. We were promised a hotel room in Montreal on the aircraft and at the exit of the aircraft, then directed to a desk after custom where me and my two kids were told that we do not get a room for the night and that we were on our own, after a back and fourth and stating what was told to us, the agent at the counter says that we are right and that we should have a room. I ask the lady if she could look into a different flight for us for the next day as I was with two you g kids and wanted them to get some rest. The gentlemen next to her jumps in and said there wss nothing without even (pretending) looking at their system, I insist and say that they could look for the kids. They seemed to have trouble with our reservation so they gave up. I told them that I needed to talk to a manager, they said there were no managers and that no one can do anything, to which I responded that there must be someone that could do something and that it does not make sense for them to repeat the same think as we are not undestanding each other. She threatns to call security and says I am rude. I say I will go, just give me the vouchers and ger response is “ not giving you the vouchers because you are rude”. I was not rude. It is normal to want to talk to a manager. I even said that the people at the counter were not resoonsible for the long journey and that there was nothing they could have done. But to threten and himiliate someone just because they ask for someone else to talk to ? I understand they are overwhelmed, but you know the quality and calibre of a company in the bad times not the smooth ones. I ended up leaving and paying for my own room and board.

Flight was great my baggage was on time everywhere but my bags had been handled ruff cause they got damaged.

I think it went very well. We flew international and felt safe and well cared for. We were on time both leaving and returning.

Three of four legs of our trip to and from Japan involved delayed flights. Hours and hours of delay. Food poor quality and inedible particularly on the Japan to Toronto segment. Two planes on the Japan to Washington return trip required replacement aircraft to be flown in from somewhere. Boarding in the dark on the field, one passenger fell and was injured. Overall bad experience.

2.5 hour delay sitting in the plane on the tarmac, you tell me how the experience was

This was my first time flying Air Canada. My first flight was delayed and then cancelled due to maintenance issues. They kept us informed and put me up in a nice hotel along with 2 food vouchers for my flight the next day. I understand things happen and they took care of the problem very well.I also like the fact that they don't charge for your first checked bag. The food was also hot, fresh and good.

There is not enough room for people over 6 feet in the seats for a flight that long. Crew only came by when it was meal/snake time, in the 11 plus hour flight we did not see anyone walk around, on our flight to Japan we did not know where the call button was to ask for water, on the flight back we finally pushed enough buttons to find the call button

I hope these comments will find their way to AC customer experience team. Me and my spouse 50 years of aged coming back from 7 days perfect vacation... While boarding in FLL flight AC1621, one of the boarding agents (tall aged african american) man literelly yeld at my wife during the picture talking process. MAM ! STEP !! BACK !!! We are not illegal immegrants beying deported, nor are we in the millitary. We are customers returning home. This was unacceptable. While boarding in YYZ flight AC1154, one of the boarding agents (tall aged caucasian) man criticied with several complesant remarks my passport condition saying that I could not travel intl with it due to stain, decoloration, and BLOOD. My passport does not have blood on it! Yes it might be in less than perfect condition, but their are ways to talk to customer that does not imply not allow a boarding agent to be angry fathery like, or a custom agent looking at a suspicious individual. Both experience were less than acceptable for might I remind you a paying CUSTOMER returning home.

Lynda was rude and unhelpful. We asked for tea wiht a slice of lemon. She served us Coffee instead. When we spoke to her she made it seem as if we were lying. I asked if she would like to taste it and see - her reply was I don’t need to be rude. After this incident we were treated with subpar service for all beverages and food items after. We’re were purposely left out when they did garbage collection.

They lost my checked in luggage, why do I pay for my cargo not arriving at the same destination as me?

This flight didn't happen for me because of overbooking.

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.
