Unless things have changed I call bullshi* on that one. I knew one bloke that was chucking bags with betweeen about 1000 hours and he couldn't even move into an operational role let alone flying within
VB - he eventually left. Another nearly had their mins and worked in an operational role, was always told this would not lead to a flying job, eventually got promised it then basically they renegged as they had no one that could do his job if he left - he walked as well.
Might have changed since but nearly everyone I've spoken to that worked for in
VB in ground positions said that transferring from pit crew to nearly anywhere internally was VERY difficult.
