What water are they testing? The drinking water on Alaska, for example, is Boxed Water. I'm not sure if that's what they use for coffee and tea, but they didn't actually mention testing the coffee or tea (that I could find).

They do not used bottled (or boxed) water for coffee. That comes from the coffee machine built into the galley, which uses the aircraft’s onboard potable water tanks. Those tanks are filled from a hose by the ground crew during refueling. (At least for major US airlines. I understand some other carriers serve instant coffee packets. Even then, the hot water still comes from the aircraft tanks.)

  I wonder how air Canada reconciles this. There was a popular globe and mail article a while ago that gave awful rankings to air Canada's water tanks -- so the company put up signs in the bathroom saying the water is non-potable and called it a day. Not super comforting if they're then using the same 'non-potable' water to make coffee...

      boiling it will remove bacterias, but not toxins (if there are any).

        Is there any reason to expect there would be "toxins", given that it's just water? I can imagine how there might be accumulated toxins it's a pack of chicken breasts left in a hot car for 8 hours, but if it's water it should be fine? After all, boiling water is a tried and true way of making water safe to drink.

Yes, there are substances that slip through, but it works well enough for most cases that it's probably fine. Otherwise you get into weird edge cases like "what if there are prions in the water?!?" or whatever.

      I guess I don't know exactly how these airplane machines work but in general ideal coffee brewing does not reach the full boiling point.

Completely orthagonal -- I absolutely can't stand the taste of the "Boxed Water" Alaska uses. I swear I can taste the cardboard or whatever they use to package it. I always bring my own water instead.
