The airline staff from start to finish were great. I had a sudden injury preventing me to bend, carry, etc..I forgot the young ladies name, but without question she immediately picked it up and began measures not only at IAD, but ALL the way to ICN Korea. She was fantastic. And, the inflight services were “super” KAL please find out the young ladies name and commend her. Very respectfully....
