Union withdraws filing to organize Delta flight attendants

The International Association of Machinists has withdrawn its filing for an election to unionize Delta Air Lines flight attendants.

Once the National Mediation Board formally dismisses the union’s application, no filing for a unionization election among the airline’s flight attendants is allowed for one year, according to Atlanta-based Delta.

The Machinists union had filed for the election in January, but said it recently found that some of the cards submitted to authorize an election had insufficient information or questionable signatures.
