Smisek stepped down in 2015 amid an investigation into whether United flew a route between Newark, N.J., and Columbia, S.C., to curry favor with the chairman of the agency that operates New York-area airports. He received $4.9 million in cash severance, along with millions more in stock grants. He also received lifetime flight benefits. (AP Photo/Manuel Balce Ceneta, File)
