NEW YORK (CNN/Money) - Albert Casey, former chairman and CEO of American Airlines' parent AMR Corp., died this weekend at his home in Dallas, the company said in a statement.

He was 84, according to the Dallas Morning News.

Casey served as CEO of the world's largest airline from 1974 to 1985, according to AMR. He remained on the board until 1991, and then held a number of positions including U.S. postmaster general.

He also led the Resolution Trust Corporation, set up by Congress in 1989 to liquidate the assets of failed savings and loan associations.

Casey is credited with leading American Airlines through the early days of deregulation and moving its headquarters from New York City to Fort Worth in 1979.

"He assembled a management team who, under his skilled leadership, guided American through the early days of deregulation and built it into one of the world's preeminent airlines," said American Airlines' current CEO Gerard Arpey in a statement.

"This airline is grateful for his extensive contributions and we will miss his friendship and support. We extend our deepest sympathies to the Casey family on its personal loss."

Casey was born in Boston and received undergraduate and graduate degrees from Harvard University. He also spent four years in the Army during World War II, according to the company.
