If US Airways Group Inc. completes its merger with America West Holdings Corp., only two top US Airways executives are expected to join the new carrier, the airlines said yesterday.

Alan W. Crellin, US Airways vice president of operations, would retain the same title and oversee the combined carrier's day-to-day operations for safety, maintenance, airports and in-flight services.

Crellin, 58, would join Bruce R. Lakefield, 61, US Airways president and chief executive, who would become vice chairman of the carrier.

But several longtime, key US Airways executives probably will not be moving to Tempe, Ariz., where the merged airline would be based. Elizabeth K. Lanier, 53, general counsel; Jerrold A. Glass, 51, executive vice president and chief of human resources; Ronald E. Stanley, 58, chief financial officer; and Christopher L. Chiames, 46, senior vice president of corporate affairs, are not being offered comparable positions, a source familiar with the executive decisions said yesterday. The source spoke on condition of anonymity because personnel changes are not yet final.

A bankruptcy court hearing is scheduled for Sept. 15 to determine whether the executives will receive severance packages.

In May, US Airways and America West announced plans to create the nation's sixth-largest airline. The airline would operate as a low-cost carrier, uniting US Airways' strong East Coast route system with America West's West Coast presence.

US Airways and America West executives hope to complete the merger by late September or early October. The new airline would be called US Airways.

The merger was approved by the Justice Department and the Air Transportation Stabilization Board, the federal panel overseeing $1 billion in loan guarantees to the airlines. The deal still must be cleared by a bankruptcy judge, America West shareholders and the Transportation Department.

Most of the senior executives who would oversee daily operations already hold similar positions at America West.

W. Douglas Parker, America West's president and chief executive, would serve as president and chief executive of the merged airline. J. Scott Kirby, America West's vice president of marketing and sales, would retain his title. Kirby's US Airways counterpart, N. Bruce Ashby, is leaving the Arlington-based airline at the end of the month to become chief executive of IndiGo, a start-up, low-cost airline based in India.

America West's finance chief, Derek J. Kerr, and general counsel, Jim Walsh, also would retain their positions with the new airline.

In a joint letter to US Airways and America West employees yesterday, Parker and Lakefield said they expect to have the new management team in place by the fall.
