WASHINGTON (AP) -- An executive who helped guide US Airways Group Inc.'s bankruptcy reorganization is resigning to become CEO of IndiGo, a startup Indian airline, The Washington Post reported Saturday.

N. Bruce Ashby, 44, will step down as US Airway's head of marketing by the end of the month, the newspaper reported.

Low-cost airline IndiGo is expected to begin operation in 2006. One of the company's lead investors is Rakesh Gangwal, a former chief executive at US Airways who Ashby served under as vice president of planning.

Ashby was also a member of the steering committee that helped orchestrate US Airways' merger with America West. US Airways executives say the merger should be competed by early October.

''It's uncertain as to whether there will be more (executive resignations) and over what period of time,'' said US Airways spokesman David Castelveter.
