I know Jyri tried to threaten the check airman group years back over this, he wanted to bring in a bunch of Riddle kids and 78 year old retired pilots to come and do sims, it was shot down. I would say it isnt normal for airlines to have in their CBAs that only seniority list pilots can do flight training. It is a great benefit to all of us that those checking and training us are the same ones flying on the line.

You can see from above that SWA, UAL and DAL all use non seniority list pilots to do flight training. Again, its a benefit to us.
