A plastic water bottle isn’t triggering a tsa pre check metal detector. I’m totally doing this next trip

They could theoretically revoke precheck for doing this, but my guess is they won't because it is a believable accident (just like people leave them in their bag all the time) and given that the sign warning about firearms mentions that even that is just a five year suspension, not permanent, my guess is they wouldn't even bother for an harmless item.

I've never done that yet I've never had any trouble finding water past security or even on a plane?!

Airport prices in the UK for recreational travel work like so:

Flight from London to Barcelona: £16

Bottle of water past security: £5

Train to airport: £26

Taxi enters drop-off area for 30 seconds: £7

A person who wants to get the advertised flight at the advertised price has to be very careful.

When people say "water" here I have to assume they mean "vodka". Otherwise you can just bring an empty bottle and fill it on the other side. It's the toiletries that pose a problem.

Some airports charge money for water after security.

Others disallow even empty bottles at security screening
