I don't get these guidelines for what you can take on board. If you take creams into the cabin they must be no more than 100ml. Now, granted, this is because of terrorists hiding dangerous chemicals in drinks, creams and lotions, etc. Fine. They have to set a limit somewhere, however arbitrary it may seem.
But why on earth are people allowed to take cigarette lighters? Have I missed something here; I thought smoking on-board was err, illegal! You can't smoke till you've landed and are out of the airport, so why would you need to carry a lighter?
