All passengers who are traveling on an aircraft are required to go through an airport security checkpoint before boarding the plane. TSA officers operate each checkpoint. To advance through security, each passenger needs an airline boarding pass and a form of photo identification issued by the government, such as a driver's license or passport. Travelers must then remove their shoes and pass through the metal detector, while carry-on bags are placed on a belt to go through an X-ray machine. Those who set off metal detectors may be selected for a one-on-one screening via either a hand-held wand or a pat down. In addition, TSA employees also screen checked bags to ensure that no prohibited materials are taken onto the plane.
All carry-on luggage must be screened through the security checkpoint via an X-ray machine or through manual inspection by a TSA employee. Individuals are allowed to bring liquids, aerosols and gels in their carry-on bags in limited quantities. All liquids, aerosols and gels must be in a clear, zip-top bag and in containers that are 3.4 ounces or smaller. Passengers are allowed one bag per person, and the bag must be removed from the carry-on luggage to be screened. A number of items are prohibited, including sharp objects, sporting goods, guns and firearms, tools, martial arts and self-defense items, explosive and flammable materials, disabling chemicals and gels. Some items are allowed in checked baggage. Prohibited items are subject to change at the TSA's discretion.
Every passenger who wishes to board an airplane, including babies and children, must pass through the security checkpoint. TSA officers are trained to understand a parent's concern for her children, and to approach children gently and respectfully. Parents and children will not be separated during the screening process and officers will consult with parents should a child be uncomfortable. Children's diaper bags toys, and carriers must go through the X-ray machine. In order to walk through the metal detector, children must be removed from their carriers, and parents and children may walk through the detector together. Necessary items such as baby formula and foods, medications and breast milk are allowed onto the plane in reasonable quantities that exceed 3.4 ounces and do not have to be in the clear zip-top bag at checkpoint. However, these items must be declared at the checkpoint for inspection. The TSA recommends that parents only carry on what is needed for the child during the flight, and any additional materials should be checked.
