Alaska Airline flight attendants reported health complaints related to new uniforms rolled out in 2011 (1). By 2014, approximately 800 flight attendants had complained about how the new uniforms were negatively impacting their health, which led to Alaska Airlines recalling the uniforms, though without acknowledging harm. The research recently published by Dr. McNeely and colleagues suggests these health symptoms could be associated with the uniforms, based on data from before, during, and after use of the uniforms among Alaska Airlines flight attendants.
