I’ve always been impressed by the cleanliness of the toilets or, at least, its frequent monitoring, cleaning, and toiletry replacements. The in-flight service by flight attendants is superb.

I’ve always been impressed by the cleanliness of the toilets or, at least, its frequent monitoring, cleaning, and toiletry replacements. The in-flight service by flight attendants is superb.

I won't hesitate to fly with Korean Air again and agian....if I can get a good deal.

The flight attendants seemed to be a little more grumpy this time. A350s could use more toilet stalls.

Excellent service, love the extra amenities (water bottles, blankets, etc.).

It was horrible. The flight crew was unfriendly and the food was absolutely horrible.

They had the same movie choice as my previous flight, not much of a choice, movies were not up to date, music was uninteresting. Other than sitting on the ground for 40 minutes after boarding the plane, with pilot telling us that they couldn't load the plane because of rain, (bullshit) We finally got into Bangkok of course 40 minutes late.

Terrible experience will never fly Delta again. Delayed flight with total disorganization and inept crew who wouldn’t communicate.

Will try never to fly Delta international again. Flight delayed and staff completely inept in dealing with it. Would not communicate, rude, completely disorganized. Once we reached Seoul the staff there had no idea what to do with us and led us around the airport from one pointless line to another. They were clearly not told how to manage the situation even though they had hours to make a plan. Never again.

They texted me my gate number and then they texted me again it’s now boarding but in different gate, and the gate was so far from the gate they texted me earlier. I have to run just to get to my flight. They always do that.

The crew and my luggage was still pretty good after a long flight. They take good care of the luggage.

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

I love my flight attendant Faith, always smiles always helpful. She makes the flight experience wonderful thank you

My return flights were changed by the airline and my preferred seat selection with extra legroom was not transferred to the new flights

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

Very dissatisfied with the fact that I had upgraded to first class for the second part of my trip only to find out that the lounge was still not available to me, as well as not having any food or drink service on the flight due to weather, so I lost out more than what I paid for.

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

The crew was outstanding. And the food was surprisingly good. The chicken and the pasta dish were both delicious and I was supposed with a pizza twist near Landing. We hit a lot of turbulence and the crew was calm and kind. Loved the TV in screen. Tons of new releases.

ANA was great. United was horrible. They bumped us from economy plus to economy and were supposed to contact us for a refund but no luck. We booked the seats 9 months in advance.

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

Comfortable as it can be for a basic economy seat. The TV screen on my 15 hour international flight went out after 1 hour or so and it never worked again. The food is very high in processed carbs and sugary items.

A three (3) hour flight should have meal service in First Class, not just potato chips!

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward into a very uncomfortable position and it is not removable.

Boarding in Paris was a nightmare for us. Why passengers have to get checked luggage tickets and then to go to counter to get luggage weight and send to the conveyor? We counted 14 security and airline checks before getting in the plane. We will never again use United or travel to France, neither stop by IAD airport.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

Finding the gate was very confusing. Our boarding pass listed one gate and the staff verbally told us a different gate.

Plenty of overhead space but forced to check my carry-ons both legs

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

Just about made it for the next flight. They need to put in longer layovers if they know they close the gate 10 min before they take off. I will never do a layover for less than 90 minutes

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

It was on time, which is always a good thing. There wasn’t any food hence my okay rating.

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.

Best flight by a pilot I’ve ever been on as a 62 year old

After multiple delays (I lost count), the flight was canceled due to a "maintenance issue". So instead of a direct flight arriving at 5:00, I had to take a flight connecting through Chicago. That flight was also delayed, partially because the plane from the cancelled flight hadnt been removed from the gate and there was nowhere for the other plane to park. (Did nobody think this might be an issue during the hours after that flight was canceled?) The connecting flight out of Chicago was delayed as well. I didn't arrive until 12:30am the next morning. I should have just cancelled the trip. It wasn't worth the hassle and stress.

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

The flight was delayed for 4 hours and the airplane was really old cuz not one thing was working.

They charge 5 dollars for plastic headphones for a flight of 1 hour! Seats are awful. Service is terrible.

Nice crew - very small plane and uncomfortable, with no entertainment options…

was wondreful! just let me know what airline im flying in advance!

On this flight, we didn't even get water offered, nor any other beverage. Therefore we got a snack of pretzels. Flight was good and Air Canada a good airline

I would realllllly like to have been in a seat closer than row FORTY. Needing assistance - longgg way to walk down and back; then they put me in the middle seat-needing to get up for the window seat passenger to go to the washroom etc.

Everything was seamless. I would have appreciated knowing there would not be any real food available for purchase in advance. Otherwise a great experience. Thank you!

The flight was delayed but at least they let us know early about it (the night before)! Everything after that was smooth!

Our seats were changed 3 times in the final 24 hours, and then my wife and I ended up with two middle seats in different rows. Full flight so no changes could be made at the gate.

Air Canada was on schedule, fast, and took care of me the whole flight. With affordable price, I 100% recommend you fly Air Canada if you are able to.
