North American Airlines (NA, New York John F. Kennedy International (JFK)) and World Airways (WO, Atlanta Hartsfield Jackson International (ATL)) parent Global Aviation Holdings has filed for chapter 11 bankruptcy protection on February 5 and plans to restructure and reemerge from bankruptcy with smaller fleets for both carriers. It is expected that lower demand from the US military for long-haul charter services has contributed to the financial difficulties the two carriers are now facing.
