Delta said a U.S. bankruptcy court approved its disclosure statement about its reorganization and set a hearing to confirm the plan April 25.
The court told Delta it could begin soliciting creditor approval of its reorganization.
Two-thirds of creditor claims, estimated at about $15 billion, need to vote in favor of the plan for it to be approved.
Atlanta-based Delta's creditors, along with Delta management, rebuffed a $9.8 billion takeover offer from US Airways last week.
Delta filed for protection under Chapter 11 of the U.S. Bankruptcy Code in September 2005.
The third-biggest U.S. carrier filed its reorganization plan with the bankruptcy court in December, stressing its interests were better served by remaining independent.
