KE is always hot. I bring a pair of shorts onboard. I generally prefer KE metal over DL if the seat is comparable (lie-flat vs. recliner).
I took KE from ICN-BKK December 13 and just yesterday settled a 36 hour delayed luggage claim. They fought my claim every step of the way and I eventually settled for less than the full amount I was out of pocket. I sat in the back, but my wife and I each had 4 seats to ourselves.
One thing I liked: After each passenger used the lav, a FA would go in and clean it immediately. They wear those covid space suits like you see Chinese passengers wearing.
