I'm going to Europe in about a month (not Spain, alas) and understand it is now illegal to pack any sort of food substance of any kind in the luggage you check in. Is this true? I've always packed power bars to take overseas for those early busses and trains that leave before cafes open, then return with chocolate, coffee, cans of olives, etc. Now EVERYTHING has to be in carry on???? How did you folks handle the new rules and regs?
