Unlimited drinks and snacks on this long flight. Very courteous Korean staff !!!

Absolutely wonderful,love the big clean plane specially the good food.

Was an easy and great flight. On time. Food was tasty and the only complaint I have is something no one could do anything about. Seems like there’s a lot of ill people in Korea these days and the flight was full of people coughing.

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.

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

Absolutely horrible. The fight member crew or not very friendly and the food was horrible.

It would be better if flight crew can clearly communicate in english. But they are kind and accommodating. Food is good, especially the sandwiches on the self-serving snack trays. They are better than the ones served. Boarding was organized.

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.

Really good! I like all the crew, they were so nice and very efficient.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

Seats were really tight and the seat belts did not give enough slack.

I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Cleanliness of seats, trays, storage pockets need more attention, but everything else was good.

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

One of the worst check in process at the DIA as well as the boarding counter Changed seat at the last minute and assigned middle seat while I paid for window seat. Requested many times but to no avail . horrible customer service and very poor process Requesting refund for seat that was changed last minute

Good overall flight. Excellent crew. Food options could be improved.

Vegan food tasted good. Restroom could be kept cleaner. Seat tray table was a bit tilted so food tray kept sliding down a bit. Flight crew can be a little more friendly, caring and approachable. Their faces lacked smiles and tone was stern.

Flight was delayed then we had to redirect for medical emergency during which time we had no information on what is the plan. The connecting flight was also delayed.

Professional & courteous cabin crew. Food was very good even in economy class

7 stars hospitality and an excellent service by the Turkish Airline entire team. Somehow, our membership numbers for mileage points were not indicated on our boarding passes issued at O’Hare Airport by the Turkish Airlines check in desk. During transit in Istanbul, I brought to attention of customer service Turkish Airlines. Please have our mileage points posted to our membership account from O’Hare Chicago to Lahore for both my wife Kaukab Shirazi Thank you

Terrible boarding experience, with an incomprehensible assignment of priorities. “Fast track” was the slowest. Poor system planning.

Terrible boarding process, no proper line maintained even for business class, crews are not very attentive, business class food quality / variety / quantity have gone down, everything has become cheap.

This was a pleasant, short flight and the crew was friendly.

Very poor. Our special services attendant gave us incorrect information. I also was mishandled at landing. There was no wheelchair waiting. I fell deboarding the plane. Appalling!

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

Boarded over an hour late, no communication, the sign just changed, no attendant to answer questions - she disappeared forever (hiding). Small plane and couldn’t hear the overhead nor understand.

Service in first class no longer exists on American Airlines .

Customer service in first class does not exist on American Airlines

I never have a good experience with American and this was no different. The airplane was INCREDIBLY hot. Like unbearably so. Everyone was fanning themselves with pamphlets and sweating. When someone asked the flight attendant to turn down the temperature they were told there was nothing the crew could do. Once we pushed back from the gate we then had to wait an hour to take off and the communication from the crew was not good. People were getting up this whole time and a man was even in the bathroom when we took off. Once we landed at our destination we waited another 30 minutes at the gate to deplane with, again, no communication from the crew as to what was going on.

Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.

First, to be fair, the flight was on time and the trip through the air was relatively smooth. But the flight was full, and they were checking carryons. As this process went on, the crew got increasingly rude and overbearing. During the drink service, a young girl (maybe 9) who had gotten up to use the lavatory got stuck behind the cart. At some point, she started feeling fearful and overwhelmed. Passengers noticed this and asked the crew to let her return to her seat. They refused. Then she started crying, and they still refused to move the cart forward to let her sit. The poor girl was trying to be brave and compose herself. The crew handled the situation terribly and with zero grace or decency. That episode, to me, encapsulates AA’s attitude toward its passengers. Disgraceful. The plane itself was cramped and miserable, as usual. There was zero inflight media or entertainment, other than the lane and borderline inappropriate jokes the steward made during the safety briefing. Then, of course, it took the better part of an hour for the checked bags to show up at the carousel. AA is no better than the el cheapo airlines these days and a far, far cry from its former self.

Everything was good till we got to yyz...then we got to the gate and there was NO GATE AGENT. We waited 15 min before disembarking. No internet No IFE Old aircraft Second leg in two weeks NOT IMPRESSED

The flight was delayed at the last moment quoting an absurd weather reason. This delay led to an issue with my connecting flight. I was made to run (literary) from this flight to the next one ( as they preponed departure. I was still in my DCA to YYZ flight when the boarding started for the next connecting flight. After my sprint to get the connecting flight, found that no place for my carry on. Had to sit for 3 hours with my back-pack on my lap , it was the most uncomfortable and inconvenient journey with little to no empathy shown by cabin crew in both flights. Another poor show from Air Canada!! Cant help because of lack of options !!

Horrible I had a health emergency and couldn’t go Air Canada refused to allow me to reschedule

First, When I check in at Phx air Canada counter, I couldn’t make it myself, either at the check in counter, the lady told me that I need a Canada visa to take this plane, then I told her that I have a lots of friends go back to China and transfer in Canada, I’ve never heard they say they needed a visa to stay in the airport, also, I have US lawful green card, as I did research, I knew all U.S. green card holders don’t need a visa to go to Canada if stay a short time. And then they agent lady asked her workmates, spent over an hour then finally have the boarding passes for me. Secondly, my flight is from Phoenix to Hongkong, one stop at Vancouver, but I had to get my bag in Vancouver then re-check in again there. I asked them, they told me that because my layover time is too long (about 20 hours), so they can’t do bags check through. I understand this, just compared with other airlines I travel before, this isn’t a good experience to me.

Excellent crew, great food despite catering issues. We need more people like this.

Very good ! I would recommande it to my friend and family

Really poor travel experience. My first flight was cancelled, which cut my international trip short and threw off my schedule. I will not be flying Air Canada again if I can so help it. The crew and in-flight experience was pleasant and enjoyable but the consistent delays and cancellations are not worth it.

I was not even asked if I want some water. Joke. Steward gave me a biscuit cover in chocolate and did not even look at me.

Economy middle seat was so narrow that I could not sit back comfortably with passengers on either side of me. Over the 9-hour flight, with my body slightly twisted most of that time, my previously-healthy left knee became very painful, even though I got up to walk multiple times. The knee is still painful 3 weeks later. Otherwise, it was a nice flight, but I was crippled over my entire vacation.

Ok Did not like that the second leg of flight was moved earlier making it a rush to make
