The attendant said: “Flight attendants will not drink hot water on the plane.
“They will not drink plain coffee, and they will not drink plain tea.”
This is because while the water tanks are cleaned, cabin crew are never informed how often they are cleaned.
Boiling water for beverages like tea or coffee usually kills the bacteria making the drink safe to consume.
However some cabin crew members aren’t convinced that four times a year is sufficient seeing as thousands of passengers travel on planes each day.
A study from the Environmental Protection Agency found that one in eight airplanes do not meet the standards for water safety, and that 12 percent of commercial planes in the US, tested positive for high levels of bacteria in tap water supply.
Therefore, it is always advised to either skip tea and coffee on-board and opt for a beverage in a bottle or can or you can purchase a hot drink before you step onto a plane.
Planes are notoriously known for their lack of hygiene, with a recent study conducted by the Canadian Broadcasting Corporation found that seat pockets were amongst one of the filthiest spots on a plane.
Seat pockets were found to have traces of E.coli, while the other areas including the tray table had traces of bacteria.
Flight attendants have previously revealed that tray tables don’t get cleaned everyday, especially when there is a tight turn around and a flight needs to get on its way.
