@stardust:
Initially you are only dealing with the headhunters and not with Vietnam Airlines; and these guys know about Aviation as much as my grandma who told me once not to fly to high and to fast because it might be dangerous.
So if you put in your application as type A320/A330 they might not find a "Airbus 320330" in ther database and you are out. You are dealing with a bunch of shortsighted laywers....i am quite sure that VNA will still need a lot of pilots in the future.
