GREENSBORO, N.C. (AP) _ Troubled low-fare Eastwind Airlines has lost $29 million in four years, and owners UM Holdings Inc. now say they are willing to sell the company for $10 million.

Eastwind boss Chris Dimitriyadi said months of complaints prompted the decision, announced Thursday, to sell or seek a merger. Dimitriyadi took the leadership reins of the company temporarily after President Terry Hallcom, three vice presidents and 10 other executives were fired in July.

The company has spent months talking to potential buyers, Dimitriyadi said. Four companies are interested, including two international carriers who want to add Eastwind's routes to their own.

The Greensboro-based company has been the subject of scores of written complaints to regulators in recent months. Customers have been angry over delayed or canceled flights and incorrect billings.

The state Attorney General's Office looked into the problems and had told Eastwind to shape up its operations. The company cut back its flights last month in an attempt to regroup and improve service.

Dimitriyadi said that Eastwind will not change its daily schedules until a buyer is found and the sale is final.

Eastwind flies out of Piedmont Triad International Airport and airports in Philadelphia, Orlando, Fla. and Trenton, N.J. The airline employs 145 workers and has two leased Boeing 737-700 aircraft.
