The Department of Justice said Tuesday that it will require US Airways and AMR to divest facilities at seven airports in order for their proposed merger to proceed.

In a release, the DoJ said the airlines would divest slots, gates and ground facilities from LaGuardia, Reagan National, Boston Logan, Chicago O'Hare, LAX, Dallas Love Field and Miami International airports.

Shares in US Airways were halted earlier Tuesday, after early reports saying that the two airlines were close to settling a state and federal antitrust suit.
