JAL though, totally different... love their service and hospitality and their meals are generally great, but the cabin temp is ALWAYS too warm for me. I'm 5'9, 160 and I have a really hard time sleeping when it's too warm. I always choose an AA 787 if possible and am very happy with space, air flow and cabin humidity seat comfort. Temp seems to generally be 70-72 Fahrenheit in all cases. Delta also seems have this same temp when I'm on transpacific or transatlantic flights. Of the Asian Carriers, Cathay has typically been the coolest in my experience. China Eastern, Hainan and Air China are just OK. JAL by far has the hottest cabins I've ever been in...
