Flown ICN-KUL route last week,
"Peach color seat, 332, no power ports."

Lounge wise, I was given choice of
some 3rd party operter Lounge at West wing(High Number Gates) or
KE Lounge at East Wing(Low number gates)
I choose to go safe with KE lounge. Although LooooooooNG walk was required after using lounge. (Lounge is at #11, gate was #48 - go figure your self)
<This inconvinence was caused because of closing of west side KE lounge, and whole construction going on due to opening of new satellite next month>

SEAT
retro style Recliner was installed, Business cabin was pretty full,
My self couldn't find the Power ports, but Portable-AVOD player was
subsdised my laptop well for entertainment purpose wise.
Just avoid front section of middle Isle seats as they don't have overhead bins

Service
2 Meals were served,
Heavy lunch right after takeoff and
some Frys & Spring rolls 1hours before land.
Variaty of beverage selection was big Plus.

Airport - Upon Landing
L1 and L2 doors are being used to disembarkation so use what ever you are closely located.
had to use Monorail to immigration,
Fast lain immigration was available for business/First class boarding pass holders. (Orange Carpeted)
Baggage delivery to corousel took good 10 minutes after passing immigration,
and seemed to be KE business class PAX was even more prioritized over MAS business class PAX.
(because of way of putting bags on plane, and ICN MH baggage folks are all outsourced by KE)

Overall decent experience for 6hours flight, I was even considering connecting at PVG inorder to catch new 777's flat bed, but I was traveling with my MUM, who denied to understand making a connection for a such distance.
