When are you flying? Im going in September and have seats on the a380 out of JFK but thinking of flying the ORD-ICN route to try out Kosmo 2.0 for the sole reason that the 747-8i Kosmo 2.0 seats have air vents. Last time we took the a380 the F cabin was a sauna. Would love feedback if you're going soon!
I'm not going until Feb 2018. I booked the return on SQ and had to base my trip around when I could find 2 saver award tickets. I'd much rather have a cold cabin than a hot one. I hope the 2.0 seats help.
