Hawaiian Airlines Threatens Bankruptcy Filing: The carrier said it may be forced to seek Chapter 11 protection and halt operations if its unionized employees fail to ratify certain modifications to their contracts. Hawaiian Airlines Inc. said in a statement that the modified contracts are necessary to consummate a pending $20-million financial investment from Airline Investors Partnership. The unions involved are the Air Line Pilots Assn., the Assn. of Flight Attendants, the International Assn. of Machinists and the Transport Workers union. The Honolulu-based carrier said it may be unable to sustain operations beyond next Thursday unless it receives additional cash before then. It said the partnership is prepared to make an interim bridge loan.
