Memphis, Tenn. ? A proposed contract for pilots of FedEx Express, operator of the world’s largest cargo airline, is heading to union members for a vote.

The FedEx Master Executive Council, the governing body of the FedEx pilots’ union, approved the proposed contract late Friday and recommended approval to the pilots.

FedEx Express, the largest division of Memphis-based FedEx Corp., and its 4,700 pilots represented by the Air Line Pilots Assn. first reached a tentative agreement Aug. 26 after negotiating since March 2004.

Voting by the pilots begins Sept. 18 and runs through Oct. 17.
