Hawaiian Airlines Unions Ratify Contract Changes: The move will allow the airline to pursue a $20-million investment offer to continue operating. The 1,200-member International Assn. of Machinists, the 500-member Assn. of Flight Attendants, the 248-member Air Line Pilots Assn. and the 24-member Transport Workers Union were asked to give up raises of about 5% for a chance to buy more stock at reduced prices and to negotiate new raises tied to profits. Hawaiian Airlines Chairman and Chief Executive Bruce Nobles said last week that the airline could stop flying after Thursday if workers did not ratify the cost reductions and the company did not get interim financing.
