If a
VB aircraft uplifts potable water in DPS it is not suitable for drinking
In that case it's not really potable water, is it, since "potable" means fit for drinking.
When almost all the airline magazines and passenger advice videos include the lines "make sure you drink plenty of water", it's about time airlines were mandated to provide a minimum of 250ml of water per passenger per hour on any flights over say 90 minutes. Consuming water may also be of assistance as part of a DVT prevention protocol. Giving it away might be cheap insurance.
Haven't flown in a heavy for a while but they always used to have water fountains with paper cups in each section near by the toilets. What's happened with that?
