I know in Japan being an FA is a prestigous job, it attracts really sharp and good looking ladies. A good number of them meet well-heeled road warriors when they're working F and get married and do the Japanese custom and quit their jobs to raise the family and manage the household.

I can't comment on other Asian countries but for the Japanese airlines, it explains why most of them are young and cute.

Here, a lot is based on senority and women have a more prominent role in the workforce than in most Asian countries, so many of them tend to make a full career as a FA as opposed to doing it temporarly. When layoffs come like after 9/11, the first ones to get cut are the younger ones who have less experience.
