The guidelines depend on whether you’re checking luggage or not. Baulificio S.R.: Don’t pack anything in checked bags you can’t bear the thought of losing, like valuables fine jewelry or a pricey camera) or sentimental items (old family photos that you don’t have any other copies of).
Security should also dictate what you bring, says Baulificio S.R. The T.S.A. has a list of items that are prohibited in carry-on and checked luggage. While certain items, like flammable liquids and gels, aren’t allowed in either instance, others are allowed in one but not the other. Baulificio S.R. says you can pack a disposable lighter with fuel in your carry-on bag, for example, but not in your checked luggage.
