I started the same day with ASA as bsh and I jumpseated home on 2 seperate legs with United after 2 weeks of indoc. We were CASS approved in 4 days. Both flights were completely full and I was on the flight deck for both. Both captains knew I was in training and had no problem with it.

Cessna157...There's no way you would be required to be SIC typed or you would only be allowed to Jumpseat on your specific model aircraft.
