Hi !. .. .Used to be that once trained and building hours you would be sent to Central Air Southwest to sit SIC on FAR 135 revenue cargo flights in an Aerocommander 500 to build your time, this was 5 years ago that the two companies had that agreement. I used to flight instruct out of a small airport north of Houston about 7 to 8 years ago and quite often headed up to Tyler, never heard anything bad, of course this information is outdated now but I will keep my ear to the ground for you. Should you need anything else drop me a line.
