Wife just came back from National Board travelers association, global organzation comprised of global financial and consultant firms. Delta was represented by a major player and advised specifically that comair does not produce the income to debt ratio and decision has been made to offset this cost to delta. Just relaying what was said.
As for the comment on Wings, I personally have seen the wings as well as worn by an FO in GSO last week. The overall sense is that comair will no longer be affiliated with Delta.
