RDG,
For pax, it's around 2 weeks here and there. For cargo, I am not too sure.
If you are an instructor, it's a different story.
But on the whole, it's about 2 weeks.
It's kind of enough for me though. I am sort of a loner and prefer more alone time.
About A380 crews, I've heard rumours that the crews have already been chosen and briefed. I myself have not been chosen or such so I don't think I have the right to comment. But none of the people I know have been called up yet. Rumour or not, someone please enlighten me as I would also like to know.
