There is a shortage of regional CA, this will continue in the near term.

The 50 seaters will greatly reduce. 76 seaters will replace much of this lift. Same seats, fewer pilots.

Mainline will replace some of the 76 seaters. Same seats, fewer pilots.

On top of this, regionals will merge and some will go out of business.

It is a distinct probability regional flying will become part of mainline, to give them seniority numbers. This will attract and retain pilots.

I have predicted several years ago, regionals will shrink to 1/4 the number of companies (already several are out of business). Number of pilots flying regional planes will reduce to 1/2. This is already happening.
