An American Airlines plane sits on the tarmac at the Great Moncton International Airport, in Moncton, New Brunswick, after landing due to a report of smoke in the cockpit.
A federal labor-relations agency has scheduled an election this month to decide whether American Airlines customer-service agents will be represented by a union.
Fort Worth-based American tried to block the election sought by the Communication Workers of America. About 10,000 agents will be eligible to vote.
The National Mediation Board originally ordered a May election, but American sued over what percent of agents the union needed to request an election .
The mediation board Wednesday said it was proceeding because American had not won a court ruling to block turning over mailing lists of potential voters. Voting begins June 21 and will end Aug. 2.
American's parent, AMR Corp., filed for Chapter 11 bankruptcy protection last November.
