The lead labor negotiator for AMR Corp. pilots said that a merger between AMR and competitor US Airways could save $130 million a year in cuts to bankrupt airline's pilots' union, Reuters reported yesterday. Neal Roghair testified in bankruptcy court yesterday that a merger would lower to about $240 million the projected annual cuts from the Allied Pilots' Association, which represents 10,000 pilots at American Airlines' bankrupt parent. The company, which filed for bankruptcy in November, said that it needs about $1.25 billion in annual labor concessions, and has proposed a business plan to achieve those savings that has left its unions livid.
