The airline ordered 100 Max 10s in 2022 and deliveries are expected to begin in 2025, its first Boeing order in more than a decade. The Max 10, the largest model of the 737 Max, has not yet been approved by regulators.
“We certainly will not take them ’til we have 1,000% confidence that that plane is fully secure, fully safe and … everyone has signed off to that,” Delta CEO Ed Bastian told CNBC’s Scott Wapner.
The 737 Max, Boeing’s best-selling aircraft, has had a troubled history since deliveries first began in 2017. It was grounded for almost two years in the United States after two Max aircraft crashed: one in Indonesia in October 2018 and another in Ethiopia in March 2019.
Most recently, the FAA grounded the Max 9 after a door plug blew off an Alaska Airlines flight on Jan. 5. Boeing this week appointed an independent advisor to lead a review of the Max 9 while inspections of the aircraft continue.
Delta flies over 500 Boeing jets a day, but does not fly either the Max or the 787, according to Bastian. Alaska and United are the only two U.S. airlines that operated the now-grounded Max 9.
Boeing has lost ground to competitor Airbus as a result of the issues with the Max. It had a roughly 42% share of narrow- and wide-body deliveries last year.
“Boeing is such a vital part of our industry, our history, and we need them to succeed,” Bastian said.
