From friends:
VOZ have made no promises nor provided any avenue for promotion or a career. There has been lots of huff n puff about getting something in writing but it hasnt happened.
Most will sit in their prospective seats for many more years unless expansion ramps up.
Nowhere does it say that VOZ cant hire more DEC's if there isnt enough interested
VB pilots.
Hell, even
VB took DEC's very recently on the EMB.
For the record, a/c 4 has already arrived.
Good luck.
