hi all i've just checked in online for my flight tomorrow and i was wondering if you can put a can of hairspray in the suitcase... it's never been a problem before.
don't use it myself, but have packed other aerosols with no issue, i'm sure you'll be fine
though given how many use hydrocarbon propellants, i'm always intrigued that they allow them on planes, and of course the tsa allows alchohol in checked baggage, but not flammable liquids
never expect consistency or logic in air transport security
