Started flying in 1976.

in 1978 deregulation was going to create thousands of new airline jobs.

It did. No shortage.

Wages have been cyclical as pointed out, but, over time have trended down. No shortage to drive the pay trend line back up.

When push comes to shove hiring requirements change. No shortage.

I have been watching this for 33 years. No shortage yet.

If you are waiting for a shortage to make things better, you are going to be waiting a very long time.
