Study: Some Airlines Provide Unhealthy Water to Passengers

Airlines are serving potentially unsafe water to passengers, prompting researchers to recommend bottled water and caution against drinking coffee or tea onboard.

Major U.S. airlines received varying grades, with Delta and Frontier earning top marks, while American, JetBlue, and Spirit scored “D” ratings. The EPA’s Aircraft Drinking Water Rule requires testing for contaminants, but enforcement is lax, raising public health concerns.
