Overall, very uneventful and pleasant experience. Most importantly, no delays.

Not very comfortable seated in the back plane due to turbulence

Everything about Korean air is great, hands down! Will always prefer this airline from other carriers.

I enjoyed flying on Korean Air. The service was great and the food was yummy. They served white fish.

Ford not that great the seat not to big for leg room like other airline

It was ok. Not good and not a bad experience

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

Not accommodating ground staff On board slow service Crew members not very friendly

lunch was good; breakfast was kinda meh cabin temprature was way too high new entertainment system but somewhat limited content

Boarding was terrible. My wife uses a wheel chair and she was in an incredibly hot closed metal cargo box for close to 20 minutes before getting on board

Only water and pretzels served on six hour flight. Did not see crew rest of flight. No video screens and so no wired audio. Poor sound on plan so did not understand anything said by crew. This is a safety issue. Electrical socket did not retain charging block so could not charge phone. No video screen so could not watch movies. Phone is not a substitute.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

I like the non stop flight to Lagos. The cabin crew were great, the food was alright and the ride was smooth. The downside is there wasn’t wifi connection from Lagos to Washington as stated. The 11hrs flight, became boring at times because of no wifi.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

One of the best flying experiences I’ve ever had.

The flight cancellation and process for getting a new flight was not that clear. United also had some delays that were unexpected. I am the most disappointed by the fact that I originally bought a Lufthansa ticket, only to be flown by United.
