Study ranks airline water quality; report urges passengers to avoid tap water

A new study from a New York–based nonprofit health researcher ranked the water quality on major U.S. airlines, evaluating contamination levels and other safety factors. Delta scored the highest with a perfect five out of five, while JetBlue and American ranked at the bottom with scores under two. The report advises passengers to avoid drinking tap water on flights and to skip hot coffee or tea when possible.
