All children must pass through the Transportation Security Administration (TSA) security screening checkpoint at the airport. Children must be removed from carriers or strollers before walking through the metal detector. While parents may hold small children, the TSA recommends that all children who are old enough walk through the detector on their own. All of the child's toys, blankets, stuffed animals and other items must be passed through the x-ray scanner and may not be carried through the metal detector.
The TSA allows persons traveling with young children to carry breast milk, formula and juice aboard the plane in excess of 3.4 oz. when the liquid is declared at the security checkpoint and is inspected by an officer. Teethers and baby food are also allowed on flights, notes the TSA website.
While children under age 18 traveling domestically are not required to carry photo identification, all children, including babies, traveling by air to or from international destinations must travel with a United States passport, according to the U.S. Department of State. Ensure that the child has applied for a passport well in advance of an international trip, as passport processing takes several weeks.
