Boeing is poised to secure a deal with package delivery company FedEx for 25 more 767 cargo jets, in a contract worth roughly $5bn.
Representatives from both firms discussed the contract over the weekend in Seattle, according to Bloomberg.
Spokespeople from both camps declined to comment on the situation, with Boeing reps saying they didn’t discuss talks with customers.
FedEx have an existing contract with the firm and upgraded to the 767 freighter in 2013 for its domestic network, providing improved fuel, maintenance and cost savings over the MD-10 freighters it replaced.
FedEx already operates 23 Boeing 767-300s and is the only Boeing customer for the plane, although a version designated the 767-2C is the platform on which the company is building a new US Air Force tanker, the KC-46A.
