Airport security has become complicated, so be prepared and know the rules so you can get through security without delay.
Passengers are allowed to carry on liquids, gels and aerosols in containers that are 3 oz. or smaller. All containers must be in one quart-size, zip-top, clear plastic bag that must be taken out for X-ray.
Sharp objects such as box cutters, knives (except plastic or round bladed butter), razor blades, swords and ice picks are prohibited from being carried on. Scissors with blades less than 4 inches long are permitted.
Baseball bats, hockey sticks, golf clubs, ski poles and other sports equipment are not permitted as carry on.
No weapons are allowed, including guns, any explosives, flammable items, disabling chemicals, mace and stun guns.
If you are unsure whether an item is allowed to be carried on, it is better to check it than having to deal with airport security incidents.
