The F/O pay is comparatively low, and the aircraft are relatively new. They are operating -800s and have recently taken on a -400 to fly the VIP operations.
Management is all ex military... which is how they airline is run. Pretty good guys and straight forward.
They fly world wide, stay in pretty decent hotels, and you won't starve while you are flying as the crew meals are pretty good and plentiful.
It is not a commuting job... so you need to take that into consideration. The average age of captains are in their '40s... so upgrade is going to take quite a while.
But on a whole as far as charter carriers go in the US... Miami Air is probabaly the best one to work for.
