US Airways Group Inc. and American Airlines parent AMR Corp. are in the final stages of negotiating a merger, with the final price and management structure still to be resolved, Reuters reported on Friday. The two airlines, as well as AMR's creditors and its bondholders, have focused their efforts in recent weeks on reaching a merger agreement, and a deal could come in the next two weeks. AMR's board, which has not made a final decision and still considers its own restructuring plan as a viable one to revive the airline, plans to meet on January 28 and January 29 to discuss the latest developments in the negotiations.
