In April of 2003, Carty and his executive board struck a cost-cutting deal with American's labor unions, intended to mitigate AMR's upcoming $1 billion first-quarter loss. The deal unraveled several days later, when unions learned that AMR executives were keeping $41 million in retention bonuses. Several AMR board members, most notably University of Oklahoma president David Boren, called for Carty's resignation.
Carty resigned on April 24, 2003. He was replaced as CEO by Gerard Arpey, and as chairman by Edward A. Brennan. He remains on the board of directors at Sears, Roebuck and at Dell Computer.
