Not very comfortable seated in the back plane due to turbulence

We were seated at the back and that was very uncomfortable for me with the turbulence we experienced on our way to Chicago.

I enjoyed flying on Korean Air. The service was great and the food was yummy, especially the bibimbap and cold spicy noodles. The only thing that bummed me out on this red-eye flight was that my seat did not properly recline so I was not able to sleep.

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

On time and flight crew are always so happy to help and always smiling unlike other airlines.

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

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.

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

The overall flight went well and the aircrew was pleasant.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

Not impressed with check in desk staff at Vancouver airport. Not a professional mind service and not cared or tried to help. Don’t think I would fly with them again

Flight crew was especially thoughtful and attentive, made sure our seats were comfortable so we could rest on the long flight

Very comfortable flights. Not so many new releases in terms of films.

Lounge in pukhet not good Very nice new aircraft Super crew as nearly always with Cathay

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

We were delayed an hour leaving Munich (No fault of the crew). They kept us posted on the status so we knew what was going on, but as a result we missed our connection in Chicago and the communication on connecting flights was pretty poor as we disembarked. It was already stressful and some of that could have been reduced by better communications about where to find transfers, etc.

One problem, but a serious one - the plane is built with electric windows that tint dark to reduce light. Sitting next to the window is VERY UNCOMFORTABLE as it emits so much HEAT in the face when tinted.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Wifi wasn't working on one of the UA flights after boarding.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

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.

Overall, I would have to say my experience with Air Canada was mediocre their DC tens. Need to be updated not comfortable at all. Only one out of my four flights was decent. The staffing was very nice. Going through customs in Montreal was quick and easy. Air Canada has room for improvement with their facilities.

Everything was great. I really like how they had their safety film set up showing you the beauty of the country.
