I routinely conceal large bottles of liquids on my person while going through airport security. I've probably gone through airport security in various places with a 1.5L bottle of water more than a hundred times now. Haven't been caught once, although of course the US-style scanners could presumably defeat this.

Same with hot sauces, perfume and the occasional bottles of wine. I really don't like to travel with a checked-in luggage, so this is a frequent problem.

Luckily I own lots of Rick Owens clothes with large hidden pockets.

As for me, my our bags have been taken off the line to be inspected the last 3 times someone in my family forgot large toothpaste tubes in their carry on.

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.

its very much about looks. Uk airports (used to?) seize aftershave in bottles that are the shape of grenades. Its very obvious what they are (made of glass, branded, spray out aftershave) but they are banned nonetheless.

  • The real question here is whether you can buy the exact same bottle again in the duty-free after security.

  • I've flown with someone who simply said she has prescription medication with her.

    I mean it was the truth. It was legitimately prescription medication. In this case. But I can imagine someone could lie.

Yeah I also regularly bring a razorblade (for my old fashioned safety razor). I have got caught once but it's worth the risk of wasting a few minutes.

If this was really about security, it would be set up so that just deliberately breaking the rules for the sake of minor convenience actually had some consequences.

If I wanted to blow up a plane with liquid explosives I would just... Try a few times. If you get caught, throw the bottle away, get on the plane, and try again next week.
