It’s great, long flight and arrive safe at destination

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

I can't believe they put my wife and I in the two middle seats! It is a very long flight and we had single flyers on either side of us blocking the way to the bathroom! There's no reason to not give one of us the isle seat so we could have managed bathroom needs and snacks with convenience. So I think very poorly of Korean air to put us both in the middle, I've never had that happen before and will probably avoid this airline in the future because of this. We tried to have them change it but they didn't so you pretty much lost a customer because of it.

One of the flight attendants stepped on my foot. I was on the aisle seat. A lady inside needed to get out. So Instood. Just then, a flight attentendant came wuicklybtheoughbthe aisle and stepprd on my sock covered toes. I let out a small sound. She stopped momentarily, but didn’t ask how I was just took off of the aisle. Never came back to see how I was. Fortunately, I was not really hurt other than a slight soreness in my toes. But I found that to be very negligent.

This was an amazing flight. The crew was great. The service was great. The food provided was great.

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

They were very accommodating of a dietary issue. Nice movie & tv selections. Non-stop helped get through a very long (15 hr) flight

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

My baggage is lost. Flight cancelled, Rebooked ticket through long routes. Mental stress, emotional hurt

The flight overall was good. The attendants did a good job except that 1 female had too much fragrance on. The other things that made the flight unpleasant were out of the airlines control.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I would love the entertainment center to be updated with more content. The flight to Doha had more options than the one to Miami

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

I felt that when I was rerouted it should have been to business class.

The flight was smooth Thank God but the delays and changing gates for 3-4 times made me so tired of walking back and forth with heavy bags I thought I was going to pass out with heavy headaches but Thank God finally found the final gate and home safe. These delays happen anytime for important reasons so just be patient when you come across these situations.

Nice comfortable flight from Barcelona back to the states. The premium economy offers the extra room we need for my husband. The food was good and our flight attendants were excellent.

the trip to madrid was uncomfortable with my legs touching the seat in front of me

Very crowded flight but what can you expect these days?? Crew was accommodating.

Small outdated plane from Philly to Des Moines with very uncomfortable seats. The plane was old, so we had mechanical issues that delayed us for 3 hours with very little communication. It was a very unpleasant experience and I will try to never fly AA again.

The seats in economy were appeared to be quite thin and lack sufficient cushioning to be comfortable. Perhaps it was my seating position but the plane seemed notably load.

Internet was a bit expensive and did not work ask that week otherwise a good flight

They don't make it easy or promote their food options. Dirty plane. Delayed.

International baggage recheck process in Philadelphia was a disaster. Waited 1 hour and 45 minutes to receive our bags. Waited 15 minutes to recheck bags, flight notification boards were blank so we asked an AA representative for our connecting gate and we were directed to the wrong terminal and gate. Our connection window was over 3 hours and we made our flight by 5 minutes. We pulled away from the gate and sat on the runway for 1 1/2 hours. 1 of our 4 bags didn’t make it to Phoenix. The mobile app for lost baggage didn’t work, the AA rep had to manually fix.

I miss my flight and they could not rebook me that day because the other flight was full, and for the next day I had to pay a whole new fee again which I think is unprofessional

The flight had a delay that made me being in a real rush to take the second flight. The delay was almost for 2 hours. They moved us from gate to gate in 4 times. Once I arrived to Philadelphia, I got to run thorough all the airport, as the train was already closed by that time. So I got sick with asthma for all the running I had to do. And I was the last one to board, when it was almost closed. So irresponsable with the people
