Scott, who is currently director of financial reporting, will assume his new role on January 1, with Healy standing down on March 31.
Healy joined Thomas Cook in May 2012 and over the last five years has led a restructure of Cook’s finances to support the transformation of the business.
Following his retirement, Healy will continue to oversee two of the key areas of future growth for the group as deputy chairman of Thomas Cook China and chairman of Thomas Cook Money.
Frank Meysman, chairman of Thomas Cook, said: “Michael will leave Thomas Cook a much stronger and more resilient business than the one he joined five years ago.
