American Airlines CEO Robert Isom said "Boeing needs to get their act together" over ongoing quality issues that have grounded planes. Isom joined other airline CEOs like Southwest's Bob Jordan in publicly expressing frustration with Boeing's manufacturing problems. Alaska Air estimated it will incur $150 million in costs from the recent grounding of Boeing 737 Max 9 planes after an accident. Southwest said it no longer expects to receive the smaller Max 7 model this year and cut delivery expectations due to Boeing's supply challenges.
