Not sure if you've been in an airport, but you can buy a bottle of water and bring it on an airplane.

[mschuster91]

Yeah, and it costs 10x as much as in a regular super market, despite being the same water.

I really, really dislike flying. Not because of the flying itself, but because of being treated like a potential terrorist all the time.

So carry an empty bottle/tumbler/thermos and fill it up at the water fountain?

[mschuster91]

You're not allowed to do so, at least when I tried taking an empty bottle it was confiscated (Munich Airport, EDDM).

Strange, I've been traveling with a 500cc refillable water bottle forever, never had any trouble (Germany, Netherlands, East Asia). Maybe it helps that my bottle is designed to be refilled, and not just an empty bottle from the supermarket.

[hueving]

That's definitely not true for any airports in the US. Finally a category where US airport security is more sane.

[gmac]

Commonly there is no water fountain.

[ZanyProgrammer]

I've seen a lot of airports (recently PDX and O'Hare) that have water bottle filler up dispensers past security.

[JimmyAustin]

There is always a bathroom.

[gmac]

Yes ... but sometimes only hot water is available, and at all times the quality of water not marked 'drinking water' could in principle be suspect (it might come via a tank somewhere — this is certainly common in old UK domestic plumbing — and the tank might have dead rat in it, etc.).
