It’s not as if you can smoke

Colin

The explanation is simple:

A cigarette lighter costs around £1.50 in the air side duty free; whilst a bottle of decent scent will set you back anywhere between £50 and £100.

It's about as logical as them confiscating any liquids deemed flammable before going air-side, whilst at the same time selling you as much highly flammable spirits fifty yards down the corridor as you can set fire to and smash to use as a weapon.

But then they are making money from the latter and not the former aren't they.

Because the fluid content of the lighter is less than 100ml, and the fluid content of the perfume is more than 100ml.

The very clear rule is a standard plastic bag of items <100ml each, in total <1000ml.

Simple.
