The vote by the Atlanta-based airline's rank-and-file pilots was 61 percent in favor, the union said in a memo to pilots.
The agreement, which runs through 2009, would take effect Thursday, assuming a bankruptcy court judge also approves the deal at a hearing later Wednesday in White Plains, N.Y. The government's pension insurer has objected, insisting that a $650 million note and $2.1 billion unsecured claim that Delta has promised the pilots should belong to the agency if the pilots' pension is terminated as expected.
The concessions deal is subject to final approval by the court, though it is unclear when the court will rule. If the deal does not get final approval, an arbitration panel would again consider the company's request to reject its contract with the pilots so it could unilaterally impose the cuts it wants. Delta, the nation's No. 3 carrier, believes the deal will be approved by the court.
In a letter to pilots after the vote was made public, Delta's top three executives said the ratification by the rank-and-file marks a new start for the airline.
"If we seize this opportunity rather than squander it, Delta Air Lines once again can proudly become the gold standard of the industry," the executives said.
The chairman of the pilot union's executive committee, Lee Moak, said in a statement that the agreement the pilots ratified "provides a framework for Delta to successfully reorganize and emerge from bankruptcy ready to win in today's competitive marketplace."
The Air Line Pilots Association, which represents Delta's 5,930 active pilots, has said the agreement reached in April between Delta and union negotiators is in the best interest of the airline, its pilots and its creditors. The cuts are in addition to $1 billion in annual concessions the pilots agreed to in a five-year deal in 2004.
In its objection to the new deal, the Pension Benefit Guaranty Corp. believes it should get the $650 million note the company has promised the pilots if Delta terminates their pension plan. It also wants the $2.1 billion unsecured claim the pilots have been promised.
The PBGC made a similar objection during the bankruptcy case of UAL Corp.'s United Airlines, but dropped its opposition to the Elk Grove Village, Ill.-based airline's plan to terminate its employees' pension plans after reaching a settlement with the company that promised the agency up to $1.5 billion in notes and convertible stock in the reorganized company.
Separately, a retired pilots group had objected out of concern the deal would ultimately reduce their benefits based on the pension being terminated. But their objection was expected to be resolved at Wednesday's hearing.
