Hang in there
Wicked shimmy,
Perhaps you are a little too pessimistic.
Have you researched how many new 400s are planned to arrive in the next year or so, and the number of new but empty pigeon holes in the crewroom?
Do you realize that for every new F/O there is normally a training requirement for an upgrade of classic F/O to 400, 400 F/O to classic command and classic command to 400 command? The training section is flat out, and the captains are working pretty hard as well.
Nothing happens overnight.
When you consider a lot of those in QL may not have got in first go, probably spent several years in GA, had an absolute minimum of 1500 hours and 500 twin, if not the 3000 or so that was the norm, and then had to serve five to six years to get a command, and then not always at their home or desired base, you may not get much sympathy from them, not that you were seeking it of course.
After too many consecutive CB-SY-CB runs, your enthusiasm may even wane a little.
Have patience and good luck.
You might even enjoy some GA experience in the meantime.
Cheers, harrowing
