Could be. Could just be sample size. Could also just be that most babes worth their salt fly first class, not in coach, and most babes in coach either have their own babes (babies usually) or are jailbait. Also could be just that the bad experiences tend to carry more weight than the neutral (which is really most flights anyway) or the moderately ok (such as glimpsing a babe nearby...it is pleasant but far from transcendent).
