How are these scores so vastly different between airlines?
I understand the water sources may vary (by airport? not sure?), but if the planes are largely manufactured by Boeing and Airbus, how are the onboard water sources / distribution systems getting contaminated?
Delta being a 5.00 means they're doing something different, but what is it & what control do they have over the plumbing, water systems, etc.?
