Reaping the benefit of a worldwide recovery in air cargo, even amid fears of a global trade war, Boeing on Tuesday announced a big order from air package delivery specialist FedEx Express. FedEx ordered a dozen 777 freighters, for delivery between fiscal 2021 and 2025. While that’s too late to help fill out empty delivery airplane slots on the assembly line in Everett between now and the introduction of the new 777X model in 2020, it will help bolster production in the early, slow-production years of the 777X. In addition, FedEx ordered a dozen 767 freighters for delivery between fiscal 2020 and 2022, vindicating Boeing’s decision to increase production of that jet by 20 percent from 2.5 to 3 jets per month beginning in 2020. The combined 767 and 777 order for 24 widebody aircraft is valued at $6.6 billion using Boeing’s list prices.
