I hate to keep showing up....but. I actually worked for scenic for a very short time. The DC-9 operator in LAS I worked for went out of business and, needing a job, I applied with them and was hired as a DHC-6 Captain (had previously flown the type during my first airline job) I attended their ground school. Due to certain events I didn't stay but....Seemed like a very professional place to work. They have been in business for many years.
I hate to tell you this but the u.s. operators are a breed of their own. One resume will probably not do it. You have to communicate with them at least bimonthly (that holds for most any u.s. operator). Keep sending your resume and, if possible, call them and confirm they have recieved it. They like consistency and interest.
Good Luck.
