Oh and just a few more clarifications on how reserve works.

If I were to go 145 and commute ORD until I’m senior enough to transfer to MIA, do I again have to do reserve until I’m senior enough to hold a line?

If instead I pick 175 and commute until I can upgrade, then I’m not seatlocked so I pick 145, I would have to continue to commute until I’m senior enough to MIA and then reserve there until I can bid a line, correct?
