Buckly's and no chance getting in direct entry on the 757 (or 767 if PX ever get one again
). You simply won't get a lookin based on seniority, unless you are a PNG national but even then you would be very very lucky to even be considered unless you are a wantok of someone high up in managment. Even know the airline has a shortage of crews, they are filling the 757 openings from within.
On the other hand if you want to fly a Dash 8 or a Fokker 100, apply. All applications nowdays have to go through the HR department I believe.
