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.

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.

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?

The leg room, complementary WiFi and food and drinks. Friendly staff

Crew was great, plane was old and uncomfortable, food was barely edible

It would have been better if the airlines would of have the gate ready to go instead of waiting 30 minutes for the other airplane to take off

Everything for a 9:30 hour flight was fine. Seats are not very large, but worked. You should get up 2 or 3 times during that duration flight for your legs sake. Food needed more Protein meats for me. I have to check on a diabetic meal in future. I don't do sugar, so very little too eat. Flight was cheap so I am willing to look over other amenities. Everything else was great

Most of the crew was wonderful but I had one bad experience with a crew member. When realizing my seat did not have an outlet compatible with my phone charger that I would need for transportation upon landing I asked an older, blonde heavily madeup member (I am describing her as I did not get her name) if there were chargers elsewhere I could use she said no, that not even the flight attendants had access to any. This however being my second flight of the day with Hawaiian airlines on a similar plane knew that chargers were available in extra comfort seating. I asked another passenger if I could use their plug and they agreed. She twice berated me for this and when I asked her to please stop talking to me about it she yelled that she was writing me up and ran down the aisle and did not return. I found this behavior disturbing. The other passenger was not bothered and this didn’t appear to be a safety hazard to anyone but it seemed to enrage her that used a plug that was not next to me.

Friendly crew. One seat didn’t have a window and another no foot rest.

Free WiFi was much appreciated. The only choice for food being a pepperoni sandwich was disappointing.

The food was good but for the landing we had to wait 30 mins for the other plane to depart to its destination

Food can be more healthy instead of processed. Crew was friendly and courteous. Our flight time changed so they gave us extra comfort seats which was very nice.

Starlink is a big plus and great customer service - boarding agent and the flight attendants

Maybe add a seat trade app for flyers that didn’t get seats together

It’s been awhile since I have traveled on United. I, along with my family who were on the flight noted how smoothly everything went . Boarding, flight crew and service was excellent.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence.

There's just no way to sit fully upright and comfortably in these seats. There needs to be 2 more inches of room, and that's not something that only one person on the flight needs - the whole flight needs 2 more inches of room. If that means you sell 6 less seats, so be it. It's too close for anyone. Forcing people to pay for "premium" economy just to get "barely enough space to breathe" isn't really an answer to that.

The crew were very nice. The Chocolate is good and v there’s no entertainment. Thanks

The crew were very nice. I would have appreciated a pillow for comfort. I had a special meal that was sloppy, but the salad was great. Thanks

I liked all the informational texts. I always knew where to go and when .

Boarding is very confusing. They have Line 1 and Line 2 and many many Boarding groups. Everyone lines up under those two lines long before they call zones. If you have a higher zone 2 like I did due to a Premium Plus ticket, it’s very awkward having to ask each person which zone they have. Extremely chaotic process. On board the flight attendants had no charisma whatsoever, even to us paying extra for an upgraded cabin. I asked for a chamomile tea after dinner (as no coffee or tea was even offered) and the FÃ said they didn’t have even though listed on the drink menu. Also, the mid flight service was entirely skipped which was a soup and sandwich combo. Supposedly had a variety of snacks mid flight too but those never materialized either. A few times I walked Back there, not a single flight attendant acknowledged me as they were all deep into their iPhones. I simply Wanted a glass of water since ZERO water runs were made on this 9hr 30 min flight.

Liked the hospitality . The ight took us 6 hrs to get from fort myers to ewr.

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

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

Overcharged by either United or Air Canada. Abuse of access to my credit/debit card.
