At Piedmont, you're guaranteed to get your #1 choice of base (so long at that choice is PHL). I don't think anyone has been assigned MDT recently, although has been a TDY (temporary duty) assignment for a few months. But that comes with its own set of rules and benefits, and there have been plenty of volunteers in the last couple of months. The latest bid had only 1 TDY slot. Current junior FO in Charlotte in April is Aug '22 hire.

It doesn't matter if you live 10 minutes, 3 hours, or 13 hours - short call reserve is a 2 hour call out. Plan accordingly. If you need a crashpad for reserve, it sucks, but that may just be the reality if your unable/unwilling to move. Good news is that it will temporary. Also good for you, with PHL being junior, you won't have to worry about any of this.
