ATA Airlines to reorganize under bankruptcy protection

ATA Airlines to reorganize under bankruptcy protection    ATA Airlines, the 10th-largest airline in the United States, filed for Chapter 11 bankruptcy Tuesday, joining United Airlines and U.S. Airways in seeking protection from creditors.
   Delta Air Lines has warned it is on the verge of filing for bankruptcy unless it can negotiate wage concessions with its pilots.
   ATA, which also has a cargo operation that carries small packages, said high fuel prices, low fares induced by tough competition and a decline in its military charter business contributed to growing losses. For the six months ended June 30, the airline lost $90 million.
