UniFoxOs,
And maybe if we pax knew how the airport security muppets were going to interpret those rules we would know what not to take.
I'd agree for a worldwide basis, but the original poster was talking about the UK - I'd say it's pretty clear cut across the UK on what is and is not acceptable for airport security.
I fly twice a week, generally Glasgow to London Airports, but occassionally to others - it's the same at every airport in terms of what you can pass through with - that's not rocket science.
I fully support any argument about the theatre of security (to quote Bruce Shneier) - I'm an information security professional - but to complain about what are now quite clearly defined and understood rules is another thing, hence my "muppets" comment ..... this isn't about a very occassional flyer being caught out, the original poster appears to be a frequent enough flyer.
