The first thing that happened when Mary, an Alaska Airlines attendant, received a new, high-performance, synthetic uniform in the spring of 2011 was a hacking cough. Then a rash bloomed on her chest. Next came migraines, brain fog, a racing heart, and blurry vision.

Mary (whose name I've withheld to protect her job) was one of hundreds of Alaska Airlines attendants reporting that year that the uniforms were causing blistering rashes, swollen eyelids crusted with pus, hives, and in the most serious case, breathing problems and allergic reactions so severe that one attendant, John, had to be taken off the plane and to the ER multiple times.
