I've had numerous opportunities to see the flight crews for various Asian airlines, both here and overseas, and the flight attendants are basically ALWAYS young, thin, and cute (if you like Asian women). Usually they even look more or less alike (go figure), are wearing EXACTLY the same uniforms as the others (most western airlines allow different uniform pieces to be worn depending upon the season, so each FA doesn't necessarily dress the same), and they even all have exactly the same LUGGAGE.
The EEOC-style "if you can do the job, you can do the job regardless of age or rotundity" thing hasn't quite caught on around the Pacific Rim. Thank goodness.
I tried to fly asian airlines back to the states whenever possible during my 4 years of living in south Korea, they only have small petite young asian vixens as flight attendants. Korean air isnt all that bad either but they do have a few token gay korean dudes (which closely resemble ugly korean chicks) and a few haggard grandma's. But hands down asian airlines is the best, kuwaiti airlines isnt bad either they only employ young poor filipina chicks
I lived in the Napa CA yacht club for awhile. The local airport was a training ground for Japan Air lines. They placed all the pilot and their family in the neighborhood. To Americanize them they gave them the same style house, the same car, the same portable basketball hoop, (set really low) even the same little white dog. Pleasant people but they stuck out like a sore thumb.
All things being equal, wouldn't you rather have a young, attractive girl bring you what you want when you want it than have a 50yr-old "senior flight attendant" bring you what you want when you want it? Hooking up with them has nothing to do with it... Mostly FA's hook up with pilots, other FA's, people they meet in the hotels on overnights, not the passengers on their own flights (at least those that hook up AT ALL).
And as things usually are on domestic airlines, all things AREN'T equal, especially on international flights... The FA's who have the seniority to bid the cake trips across the oceans are the ones that are not only the most worn out but the ones with the worst attitudes. 'Specially those in First or Business.
