Prunezeuss,
I work with these cabin crew every time I go to work, and I also have a copy of the GD on every flight. Apart from the 2-3 Japanese crew on a Japan flight, 2-3 Korean on a Korean flight etc, the vast majority are Singaporean, with a small percentage of Malaysians.
With the pride of the "Singapore Girl" evident here, I imagine that the claim that experience as a SQ cabin crew will help on a resume is probably correct.
Would you mind enlightening us as to where you got the evidence to back up your statement?
