dv, I'll take stabs at them, but those aren't easy to answer.
1 - Where would you be commuting from? Miami? I don't know if domicile would matter that much. I haven't nonreved to/from MIA very much, so I don't know the degree of difficulty.
You need to state exactly where you're commuting from.
2 - No guess at all. It looks like the bottom of a previous class got fifi to DEN. When I went through, that wouldn't have happened. The next class could easily get SFO or ORD.
3 - Traditionally, it's been ORD and SFO. Now, I don't have a clue.
Where do you want to live and where do you want to domicile?
