Rumor has it that DE's be shortly posted on the net. Although it is probably better to promote from within, the company needs extra lift rapidly and experienced commanders NOW as they can fill all these planes they say, it could also be that these 340s won't remain in the fleet, hence the DE contracts and not investing more into full training. Keep in mind that it is a good thing that the company is doing well.
As for the pay, the suggested 12k a month plus per-diem, transport, accomodation,etc. is pretty fair, Remember that these are wide-body heavy metals, and contract folks always make more than permanent staff since they don't have a vested long term interest in the company-plus that can only improve the pay for all of us worldwide.
Good luck to those in a bargaining position!
