Is it possible to credit more than monthly guarantee while flying in Hawaii? What about the US bases?

How is the flying on the 700/900? Longer trips / fewer legs per day? I imagine that a PHX base will likely be flying out West, while the others stay in the North-East.

How likely is it to get a line quickly at the various bases, also which bases are rather junior right now?

Lastly, what kind of travel benefits could I expect?

Appreciate the info.
