I have a differedn opinion, I try to check as much as I can I just carry on my small Tumi briefcase/backpack. It is soo much easier with security now. I am, the one that always has my stuff hand searched. I guess it is because the airlines cannot believe that a 19 year old has elite status and flys first class (I am referring to some agents on an AS flight the other day) With checked bags I may have to wait another couple minutes, but at least I don't have to lug them around the airport (Really helps when I have to run to the plane (SFO-IAH-MID horror story) Checking for me makes flying easier especially in NRT when I go out to town I don't want to spend 900yen to have them hold my bag!
