If you’re reading this on an airplane while sipping an in-flight coffee, you might want to put the cup down.
According to a 2019 Airline Water Study released by DietDetective.com and the Hunter College New York City Food Policy Center at the City University of New York, “many airlines have possibly provided passengers with unhealthy water.” The study, which took seven months to conduct, investigated the onboard water quality of 11 major and 12 regional airlines, then ranked them accordingly.
Alaska Airlines and Allegiant had the best water quality scores of major airlines at 3.3, while JetBlue and Spirit Airlines had the worst, tying at the bottom with water health scores of 1 on a 0-to-5 scale.
Almost all regional airlines studied earned poor water health scores, with the exception of Piedmont Airlines, which earned a 4.33. Republic Airways came in dead last with a score of 0.44.
