An International flight from Cebu to Incheon was delayed the night before without a proper explanation. Same thing happened from Incheon to Cebu in the first leg. I will not fly Korean again. And I will ensure Delta their US partner hears about it. This is a routine by Korean to delay flights from and to Cebu via Incheon.

An International flight from Cebu to Incheon was delayed the night before without a proper explanation. Same thing happened from Incheon to Cebu in the first leg. I will not fly Korean again. And I will ensure Delta their US partner hears about it. This is a routine by Korean to delay flights from and to Cebu via Incheon.

When I selected my seats, it showed row 29 as the front row, so I paid extra to sit in what I thought would be the front row, but when I boarded the plane, row 29 was the second economy row. I was disappointed that I'd spent almost $100 more for no actual benefit.

The food is always good and that flight was particularly good.

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.

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

Although the flight left late, we arrived early. It was one of the quickest boarding and off boarding experiences I’ve had. It was kind of annoying the only drinks they had were water, coffee, and tea. The flight was very smooth, temperature was just right, and flight attendants were friendly.

Rode in a smaller plane and short trip meant no snacks, no free wifi or tv. It was only 30min flight so honestly wasn’t a big deal to lack these items.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Kind staff. Snacks are small but that’s the new normal.

Overall, terrible. Flight from SFO was delayed due to “air traffic control issues”, and we were all mislead about connecting flights. Told “you have 20 minutes to catch your connection”. Reality was 5. We got to watch the plane sit at the bridge. Won’t fly Delta with a connection again.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

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

The boarding experience was good; $20 for wifi per flight is uncompetitive compared to Delta, Southwest, and others, and puts American lower on my list given similar pricing.

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

Same as before being upgraded to business class made it perfect

I flew out of Reagan National. My flight was delayed, delayed, delayed, and then canceled ...THREE TIMES over TWO DAYS. Staff were seemingly not empowered to provide information on why the flights were screwed up. A real nightmare.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.

Flight delayed on both ends - have a gate ready at DCA, don't make us sit for 30min after being late to take off as well.

I liked nothing about this flight nor the incredible lack of service and communication on this flight from the Captain to every staff member. Arrogant, entitled and lacking any kind of basic customer service

Everything should be better, terrible flight and airport service. Delayed for 6 hours, flying around for 1 hr, and keeping us on a plane for another 2,5 -3hrs.

The plane was dirty. It appeared that Air Canada did not know vacuum cleaners had been invented. Second, the overhead bins were about 1/3 or 1/2 the size of "normal" bins. That was a problem. The worst was disembarking in the weather in Montreal. I have cold agglutinin disease. That means my red blood cells clump together and then are destroyed when exposed, even by breathing to cold air. A few seconds of exposure can be dangerous. I am now experiencing extreme fatigue caused by the anemia from that experience. I should have had more assistance descending a narrow ramp and then traversing, even if only a few feet, of icy pavement. The blowing snow penetrated my facial covering and has caused problems.

Good airport. Good entertainment on the big flight. Did not have a good way to prop up or mount my phone/ipad

I booked my flight ni November and was placed on standby? How does this happen. Flight was 1 1/2 hours late departure plane was switched to a smaller plane easy to tell this is a government run company they don’t care about anyone

Boarding was a disaster one person checking in 200 people took 25 min to check in zone 1&2.

Old, noisy plane, bad coffee, delayed. Flight attendant was very nice.

Boarding could be improved, no need to wait after a previous group is completed

We boarded 1.5 hours late. Long wait for the bags when we got to Mexico City. Long wait to get on plane with people mover truck. Friendly staff. They answered all questions as best the could. Such a long, long walk from the plane to customs. Thank you, Michael A. Burris Cambridge, Massachusetts USA

Delayed in Fort Lauderdale 3 hours , gave us $15 coupon for meals at 20:50, when most of the restuarant closed at 21:00.
