He was a captain for many years with Northwest, merged and became one of the most senior in the whole company, most senior on the AC certainly. He had mentioned he was a 26 year captain at his retirement. So since he was 39? Might have been is total years as captain also and not in a row on a single AC. But im fairly sure had been on the 757 and 767 most of his career as FO or capt. But he was the most senior or #2 in the company when he retired.
