A recent study ranks the water served on major and regional US airlines.
Drink up if you're on an Alaska Airlines or Allegiant Air flight. Those two airlines tied for first place in the rankings in the study, from the Hunter College New York City Food Policy Center at the City University of New York and the website DietDetective.com.
But you might need to exercise some caution if you're on a JetBlue or Spirit flight. They tied for last among major airlines in the study, which came out at the end of August.
A list of recommendations for air travelers from the study include warnings not to drink water onboard an aircraft unless it is in a sealed bottle or to drink any coffee or tea prepared on board.
And instead of washing hands in the airplane's bathroom, the study encourages passengers to use hand sanitizer.
