USAir Ends Wage Concessions Talks: The parent company of the airline said it is ending talks with its unions on a wage concession and restructuring package and now will concentrate on cutting labor costs by traditional collective bargaining. The airline has been unable to reach new labor agreements with its pilots, flight attendants, machinists and transport workers. Arlington, Va.-based USAir Group, which has the highest labor costs of any major carrier, has said those agreements are critical to its future. The company was trying to negotiate $500 million in wage concessions from its unions.
