And you are exactly correct that in my view at least, the point of the thread is precisely not another discussion of the merits of BoB.
What's to stop you taking an empty 2L bottle through security and filling it up airside if you don't wish to pay for water in the airport or onboard? I'd trust the water fountains in the airport other the potable water supply onboard.
I do of course accept that you can become mildly dehydrated as a result of the drop in humidity to 20% (from 30-60%) with 50% recirculated air on a flight (heck try a submarine where it is almost entirely recirculated and just purified), but we are only talking a couple of hours, not sure it will worsen any jet-lag. One should avoid drinking caffeine and alcohol before a flight if one is worried about being dehydrated by flying.
Having said that, it is interesting those who just choose their moment when CC can easily supply the water without having to either disturb their BOB service or remember it in minutes several seam to have a greater "success rate".
