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

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.

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.

There could have been better spacing of the passengers, it was crowded in some parts of the plane then other while rows were empty

Plane took off on time and I had the whole row to myself!

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 flight was a superior flight in all regards. Extremely pleasant experience.

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.

It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

delta last minute gave me a boarding pass for a different flight with no confirmation that they were changing it

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

Excellent flight and got us around tough weather. Only issue was seat TV did not work and crew tried to reboot.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

was sitting in the jet bridge for 10 minutes in -20 degree weather waiting for my bag

Very convenient considering that is a non-stop flight, but the Aeromexico still has old model planes, so the entertainment was very poor and the space for carry-on luggage was very limited.

Flight taking off must have been behind, because there was no pre-departure drink for first class like normal. Also, person in front of mine’s seat got stuck in the as far back as it normally goes position for the whole flight even during landing, flight attendant unable to fix it. Gate was not empty when we arrived, but that is MSP’s fault since was overdue for push back, not Delta’s, so had to sit on tarmac for a while and international flight so then still had to go through customs. Flight crew was excellent throughout though!

Flight from MEX to ATL had to divert to Tampa. When we got off the plane, there were non directions on what to do. Nearly 30 minutes just standing around. Finally told to go through security with no boarding passes, and turned away. Then told to to go back. Took forever to leave Tampa for ATL. Missed my connection to Harrisburg.

This long-haul international flight was the most comfortable among any of the same kind of flight operated by an American-headquartered airline - second to none!
