The missing emergency door of Alaska Airlines N704AL, a 737 Max 9, which made an emergency landing at Portland International Airport on January 5, is covered and taped, in Portland, Oregon on January 23, 2024. One of two door plugs on the emergency exit door blew out shortly after the plane took off from Portland. Alaska Airlines says it expects a $150 million hit from the Boeing 737 MAX grounding, which will limit its capacity growth in 2024. IMAGES
