The most basic requirement for airline travel is valid identification, such as a passport, for adults aged 18 or older. Passengers under the age of 18 are not required to have valid identification for domestic travel within the United States; however, their parents or guardians will need to show identification whether at the departure or arrival airport. Aside from having a valid boarding pass, the other basic requirement for airline travel is to follow the guidelines for acceptable items to carry onto an airplane.
Restricted items, such as liquids, lotions, gels and food, must be sealed in containers smaller than 3.4 ounces and displayed at the security checkpoint. Baby formula, food and milk are exempt from this rule. Sharp objects, sporting equipment and weapons are strictly prohibited from carry-on luggage and must be transported in checked luggage.
Aside from a United States passport or passport card, some acceptable forms of identification for airline travel include:
- DHS trusted traveler cards
- U.S. military ID
- Permanent resident card
- Border crossing card
- DHS-designated enhanced driver's license
- DMV-issued driver's license or other state photo identity card
- Tribal-issued photo ID (must be federally recognized)
- HSPD-12 PIV card
- Airline- or airport-issued ID
- Foreign government-issued passport
- Canadian provincial driver's license
- Indian and Northern Affairs Canada card
- Transportation Worker Identification Credential
