Delta Air Lines' flight attendants will file union cards for representation in the Association of Flight Attendants-CWA on February 14, a union spokeswoman said on Sunday.
"They want a seat at the table -- whether it is during regular contract negotiations or mergers -- so they can have a voice in their careers," said Patricia Friend, president of AFA-CWA International.
The union said a "solid" majority of Delta flight attendants have signed cards seeking union representation.
The flight attendants' move comes amid media reports that Delta and Northwest Airlines are close to a merger. Northwest's flight attendants are already represented by the AFA.
A merger would combine Delta's strong Atlanta hub and its transatlantic route network with Northwest's extensive Asia presence that includes a hub in Tokyo.
