AMR, US Airways Said to See Merger Talks Into Midweek

US Airways Group Inc. and AMR Corp.’s American Airlines still are working on details of an $11 billion merger agreement, and any announcement would come no earlier than midweek, people familiar with the matter said.

The carriers had been heading last week toward board votes tomorrow and a possible announcement Feb. 12, said two of the people, who asked not to be identified because the talks are private. That time line will slip to later this week, they said.
