Can You Bring Sunscreen on a Plane? Travel Size Rules Can you bring sunscreen on a plane? Yes - but the liquid rule decides how. Bottles and tubes count as liquids, so each must be 3.4 oz (100 ml) or smaller in hand luggage, all fitting in one quart-size clear bag. Larger bottles go in checked luggage with no size limit. Solid sunscreen sticks skip the liquid rule entirely and never leak in your bag. Sprays are allowed in the same 3.4 oz limit, but pack them upright to avoid pressure leaks.
