Four flight attendants who were aboard the Alaska Airlines 737 MAX 9 that suffered a mid-air cabin panel blowout in January last year are suing Boeing for physical and emotional harm.

In separate lawsuits, they are demanding compensation for physical and psychological injuries, emotional distress, and both past and future economic losses.

“Each of the four flight attendants acted courageously, following their training and putting their passengers’ safety first while fearing for their lives,” Tracy Brammeier, the attorney representing each of the plaintiffs, said.

“They deserve to be wholly compensated for this life-altering traumatic experience.”

Boeing declined to comment, while Alaska Airlines did not immediately respond to a request for comment from Reuters.

The lawsuits, filed Tuesday in King County Superior Court in Seattle, accuse Boeing of negligence and failing to exercise reasonable care in the design, manufacture, sale, and maintenance of the 737 MAX aircraft and its components.

“Boeing knew or should have known of the quality control issues present in its production of the 737 MAX line of aircraft,” the filings said.

The incident triggered a major crisis for Boeing and led the U.S. Justice Department to launch a criminal investigation, declaring that the company had violated the terms of a 2021 deferred prosecution agreement.

Last month, the US National Transportation Safety Board concluded that Boeing failed to provide sufficient training, guidance, and oversight to prevent the incident.
