Is it really true normal upgrade is 12-24months? (Normal=non-TDY)

What equipment and base is most junior for captains? What base is junior for New hires?

What equipment and what bases end up getting TDYs often each month? Seems like TDY is commutable.

You really get a revenue airline ticket to get to your TDY base? Does it have to be on AAY or can you really live anywhere that has a hub and fly in on any airline? Thanks y'all. I've got an interview coming up.
