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.

Glad you had Bibimbap which tasted much better than mesh potato or pasta.

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.

So far one of the good one , whenever I go to Korea , I always use Korean airline .

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.

They could have had more up to date movies/better choice of music.

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

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

Excellent service provided the flight crew. Food and drinks were very good.

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

Not enough food for everyone. . Always run out of food when we ask

I was amazed at how clean Cathay Pacific planes were compared to our US domestic airlines. Everything was great all but the food service I was just okay with. Shorter flights with other airlines usually provided more meals and snacks that I have been on. Almost a 16 hour flight just two meals and no snacks with Cathay Pacific. Even ran out of what I wanted for one of them. Other than that top notch!

The crews were smiling all the time with soft tunes when they spoke; the food was excellent. Thank you!

Cathay flight was fine, Amsterdam airport was a nightmare, spent way too much time walking to our next connection, no travelators.

They charged me $900 to board my flight I already paid for just because I missed my previous flight. I do not recommend this airline by any means.

Not good. Small seats. Not enough food that customers wanted. No special requests were given that i could see. Slow response from flight attendants

For a transpacific flight, flying economy is awful! The seats are cramped and its meant for petite folks! Good luck if you have long legs. BOARDING - AWFUL, we got to Hong Kong - the gate was listed, but upon arrival, there was a MESS of boarding procedures, they basically DIY'ed how to board but making three lines and putting three ground crew to check for passports in the terminal area. THEN to make it worse, after going through that cattle process, all of a sudden you see people standing and looking confused, apparently we were told to get in line to board, but the AV notification wasnt even working. So people started cramming in line - worse than cattle. One saving point, the flight crew forgot to serve me dinner and after waiting for it, I fell asleep since this was a midnight flight. After letting a crew know that I was forgotten, all of my meals were served first !!! Yay for being in the economy seats! Nothing much to write home about once more!

They canceled our flight and left us stranded to figure it out

We appreciated the friendly, efficient, and professional flight attendants. A wider selection of hot foods would be nice.

Did not have enough time from Venice seaport at Ravenna to get to Venice airport in order to make the scheduled flights. Need to have at least 3+ hours from ship docking to airport.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

The plane used to go to Chicago was a bit outdated and needed a refresh

My connecting gate in .Chicago was across the aisle from my arriving gate. Otherwise I would not have made my connection. So that was very fortunate.

when you can say you don't remember being at any point upset during a flight, the airline is winning .

flight was delayed and stewards were preoccupied and not helping passengers. The pilot was very communicative which was great. The window was dirty as were the back of the front seats with chewed gum and slime on it. I hope this helps.

Traveling on two legs the food was identical and not very good

Agent checking me in was great. Plane was nice. Problem was with the handling of my fragile check in. They damaged my steel drum, waiting to hear back from them to see if they will take any responsibility. Think twice about travelling with something fragile, they don't seem to treat it any different than normal luggage

I had a problem checking in as I didn’t have the correct code. I had to phone BudgetAir.com. They charged me an additional 174US for some tax or something in order to provide me with my booking number. I will never use a third party seller again. Absolutely criminal activity. But I did get to where I wanted to go

Still sitting in a hotel when I'm due for work

My trip was two parts flying from Canada to ATL then to PNS I had confirmed seats with tickets at boarding in Canada and bags tagged for said flight. Got to ATL got help to plane before boarding ended and was told at the gate that I had no seats on this flight even though I had tickets that said so I was told by a supervisor with Delta that I was booked on flight 5 hours later not the one on my ticket had to sit in ATL not knowing if my bags were on flight I was booked on or the one I was told at the gate for 5 hours later or even if I would have seat on that flight as seats were to be assigned at gate. Will never recommend West Jet product and am not sure about Delta any longer and had never booked thru Kayak for flight before and will probably never again and will be sharing my experience with who ever will listen to me about it to warn them to avoid the problems I went thru.

Terrible experience at the gate. Charged for carry on luggage despite them meeting the requirements for sizing.

It was not clear that a shopping bag with gifts would need to be checked. Lucky that my friend checked her carry on so that she could take mine on. It contained fragile items ( and expensive). Plus they charged me $100 for that last minute change.

Never been on a long haul flight that didn't have on flight entertainment. I hope the way back is better !

It was fine for a low cost trip. No entertainment and poor food offer. The sits were ok. It was on time.

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.
