Im at Flight express and really love it. The maintence is pretty good, usually only have an airplane try to kill me about twice a week, but its always "fixed" the next day.
Depending on the base you get you might have a stready run right out of ground school other wise you could be a rotation guy at a specific base until something opens up and you bid by seniority. A rotation guy only switches runs among his base, not like other companies where you are sent all over the country and on the road for long times. (it does happen on rare occasions though)
All the pilots i work with and have met at other bases have been great, we really seem to have a good group of people. Besides Flying Single Engine Night IMC in winter, at least where I'm based ought to teach you a few things.
Seriously about the maintence, it really is good, these planes are high time and used constantly, but there is nothing shady about this company
