Air Japan, Peach, Air Asia Japan, JetStar (in all their bases around SE Asia) NCA, all offer upgrade programs, you are right in the sense that there aren't many places that offer comprehensive upgrade programs but there are a few, I am one who believes that there will be more companies, specially in China that will have no other option but to offer upgrade programs in the coming years.
