wow...so many questions
okie, firstly, you will definitely be based in Singapore. SIN base crew fly to Tokyo, NYC, LA, San Francisco, Vegas (till Oct 06), Saigon (till oct 06), KUL, Osaka only for now. Each flt, max of 4 SIN crew.
I'm not sure abt SQ pay, but I heard its about 3.5 to 4k? Correct me if I am wrong. JAL starting pay will be about 2.5- 2.8k. basic will increase every fiscal year. i heard from others that SQ crew fly a lot more though. We get 3 off days after each states flt. 8 off days a month usually.
Training is 3 months. 1.5 in SIN, 1.5 in Tokyo. Involves a lot of Jap lessons.
The type of pple they are looking for...look-wise: 1.58m minimum,fair, no coloured hair, pleasant looking, no tattoos or visible scars. They will do a check on the 3rd round. Personality-wise: must be interested in jap culture, language, can't be stubborn and talk back, must smile a lot. Best if you are the sort that can apologise whether its your fault or not...hahaha... its kinda jap service culture. And must be able to take a lot of crap from passengers who can't tell diff btw orange juice and apple juice =p
Not sure what else I can tell u... hope this helps=)
