The Atlanta-based carrier also revealed that it is giving its former finance chief free flights for life in exchange for her consulting services over five years.

The agreement calls for former chief financial officer Michele Burns to provide consulting services to Delta until 2009 on issues related to her time at the airline.

In exchange, Burns, who left Delta in May to become CFO at bankrupt energy supplier Mirant Corp., will get unlimited free air travel anywhere Delta flies during her lifetime. The filing also said that Burns' spouse or domestic partner and any children -- until they reach age 19, or 23 if a full-time student -- would also get the free airfare. The company would not comment about Burns' family.

Burns will not receive any other compensation besides the free flights, which will continue after her consulting services are completed, spokeswoman Peggy Estes said. The agreement bars Burns during her service term from soliciting any Delta officer or director to go work somewhere else.
