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

as said previously, the Hawaii legs are shorter, so you'll probably com up shorter than with other bases that have longer legs.

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.

reigonals don't fly very far compared to their larger counterparts. Most trips are :30-1:30. If you want to get a better idea, google a tail number and look it up in flightaware. Iad might be expensive to live in, but most that don't want phx bid for iad/clt because the weather is usually better and is usually 'easier flying'

Lastly, what kind of travel benefits could I expect?
