US Airways, AMR near $11 bn merger, deal seen within week: sources

Horton rebuffed an aggressive takeover push from US Airways early in the bankruptcy process, saying the airline preferred to exit court protection on its own and consider a deal later. But after several months of talks with its own creditors as well as with US Airways, Horton has softened his approach and agreed to consider all options.

A combined American-US Airways would provide the scale to match bigger rivals that are upgrading service and expanding international routes. The merged company would have revenue of $38.69 billion based on 2012 figures, ahead of United Continental which had revenue of $37.15 billion last year.

The new American would have a solid presence on the important U.S. East and West coasts and on North Atlantic routes, given American's revenue-sharing joint venture with British Airways and Iberia.
