Cape Air is always hiring street captains, for the 402, assuming you have an ATP or are ATP qualified. You'll have to build some seniority before getting on the ATR though. I have no major complaints about Cape Air as a company really. You work hard, do a lot of legs (6-12 per day), have passengers breathing down your neck, and fly old airplanes with crappy heaters and no A/C, at low altitude in the wx. But your IFR and stick and rudder skills will improve doing this flying. The company does a decent job of taking care of the employees, pay is ok, we have good union representation, and you're home every night.
The biggest complaints would be:
-Lack of career progression (flying a twin piston, no turbine)
-pay (better than most regionals first year but you'll have a hard time breaking six figures here unless you have 15 years seniority and work 6 days a week)
-Bases: you can be home every night, but Cape Air has like 30 domiciles, and you have to re-bid for a base every 6 months until you are senior enough to stay put, which may take a couple years. Also, new hire captains can almost count on going to Billings, or MAYBE one of the junior bases in the midwest or northeast
