I've always heard that you should stay hydrated while flying, but apparently you shouldn't use water on an airplane! Even to wash your hands!
According to a new study, many top airlines do not provide very safe drinking water and it could make you sick! 23 airlines were checked (11 major and 12 regional) and only 3 out of 11 hit the mark and only 1 out of 12 also hit the mark.
Is there any safe water to drink on planes? See the rest of what you need to know here!
