The next time you fly Spirit Airlines, you would be well advised to make one of your carry-on items a bottle of water.

A new study from Hunter College’s New York City Food Policy Center and the not-for-profit organization Diet Detective raises concerns about airline water quality.

According to the rankings, Spirit Airlines is tied with JetBlue for the worst water.

The 2019 Airline Water Study ranks 11 major airlines and 12 regional airlines based on the quality of the galley water.

Each airline included in the study received a “Water Health Score” from zero to five, based on criteria like fleet size, the presence of E. coli and coliform in water samples collected between 2012 and 2019.

Scores of three or higher indicate “relatively safe, clean water.” Spirit and JetBlue's water scored a 1.

The report confirms what previous studies have shown: You should not drink airplane water.

Flight attendants pour drinking water from bottles, but airlines still use galley water in the coffee and tea they serve. Passengers also come into contact with it when washing their hands or even taking a drink from the sinks in the bathrooms.
