Paul,
The seniority list has to grow if the airline is to grow. Right? Or am I just really bad at math? Seems to me we are already short of pilots, at least on some fleets. So we might need more pilots to fly those shiny plastic jets coming from Airbus. I realize not all will be growth, but those which are will require about 20 extra pilots more per aircraft.
Also, you say management celebrates when a B scaler is replaced by a C scaler. Really? You'd rather have a zero or near zero experience, cheap "pilot" in need of massive amounts of training OVER a pilot with thousands of flying hours from various backgrounds already in possession of said training. Sorry, I disagree. The guy with a spreadsheet might prefer that, but he does not know anything about running an airline.
