I guess everyone here knows you can't bring blades onto the plane on a carry-on. Does anyone know about the restrictions on liquids - 100ml of balms as long as it is in a visible container? But what about soaps, some are hard and others creamy - should I be worried about getting a soap through. And does anyone have tips for getting a travel sized amount of a favourite soap scraped from a full-size bar. How do you travel without seperation anxiety?
