Inspired by this question over at MiYodeya, does anyone know of specific practices or regulations regarding the use and cleaning of water urns on commercial planes?
Specific questions would be
- are water urns on planes only used for water?
- are they washed? (or do we saw that they don't need to because they only contain water)?
- are they washed in dedicated washing machines for water urns or with other food containers/dishes?
These might seem weird questions but some Jewish travelers who observe Jewish dietary laws (i.e., eat kosher) will decide whether they can drink coffee on planes based on these answers.
