At the ALPA National BOD in 2014 I added an agenda item to the legislative affairs committee to defend the 1500 hour rule as a priority. The legacy carriers on the committee supported my resolution, and the amendment was passed to include that as an ALPA priority.
It was astounding that the only arguments against defending the 1500 hour rule came from some other elected Reps from the other regionals in the room who were concerned about exactly what you listed above. As if fixing hiring were their problem to fix.

The bonus has proven that what ALPA said is exactly correct. We don't have a pilot shortage; we have a pay shortage causing a pilot shortage. The lack of pay will eventually cause a real shortage as currently an insufficient number of people are entering the profession; so an actual physical shortage will come later also. If the compensation were better, more people would enter the profession. So, when you get down to it; it is a pay shortage.

The newly revitalized FFD Committee is doing great work, and over time will be instrumental in turning things around. It should have happened a decade ago, but late is better than never.
