Delta Air Lines Inc., the least-unionized major carrier in the U.S., dodged an organizing election to represent flight attendants when the Machinists abandoned plans to hold the vote.

Employees had turned in too many questionable cards to support the balloting, the Machinists said Monday in announcing that it was pulling the plug. The union said it would file again with U.S. labor officials to stage another election in 12 months once the effort is formally dismissed.

Pilots are the only organized major work group at Delta, which has prided itself on being a mostly non-union airline. In January, the Machinists delivered almost 12,000 so-called request cards to the National Mediation Board to seek a representation election at Atlanta-based Delta.

Delta pared an earlier decline after the union’s disclosure, and fell 0.9 percent to $41.87 at 3:06 p.m. in New York.
