What you're seeing is a protected ex-TWA captain. The company terminated Supp CC (STL CA-protected base) during the BK. The new arbitrated ruling produced new CA-protected positions on the -80 in DFW and 767 domestic in MIA. They have a right to a certain number of CA slots, and they hold those slots with their AA seniority number, which in many cases is junior to the usual LAA CA seniority. As a result many of them are on reserve. At least that's how I think it works.
