PHOENIX (AP) _ America West Airlines pilots voted overwhelminly Thursday to join a union after rejecting two earlier attempts to organize.

Of the 1,095 America West pilots eligible, 802 voted to join the Air Line Pilots Association, 28 voted for other union representation and four ballots voided, the National Mediation Board in Washington, D.C., said.

ALPA represents 44,000 airline pilots at 37 U.S. airlines.

''With ALPA, we have joined the most sophisticated and respected union in the airline industry,'' said Capt. Mike Martin, chairman of the America West Pilots Organizing Committee.

America West was the only major carrier whose pilots were not represented by a union.

Two previous attempts to form a union failed to gather enough votes.

ALPA representation ''will not deter in any way the company's commitment to further improve the dramatic turnaround that has been achieved in 1993,'' said Michael J. Conway, America West's president and chief executive.

America West, which has been operating under Chapter 11 bankruptcy protection since June 1991, lost money for 10 consecutive quarters before reporting profits in the first two quarters this year.
