The Transportation Security Administration requires all adult passengers over the age of 18 to present a valid U.S. federal or state issued photo ID. A passport is the ideal, however, a driver license or state issued ID as well as other government issued documents that contain a photograph, name and expiration date are acceptable.
Children under 18 are not required to present identification for U.S. domestic flights, but on international routes children (including infants) are required to present a valid passport to exit, enter or re-enter the United States. It may be wise for frequent travelers to get passports for all family members since proper documentation simplifies the boarding process.
Some passengers not having proper identification due to loss, theft or other circumstances must provide adequate information to the TSA officer to verify identity. This will certainly delay the security clearing process, and if identity can not be verified, the passenger (most likely) will not be allowed through the checkpoint.
If passengers approaching the checkpoint have the proper photo ID and boarding pass out and available for review, it will expedite the security check process. Birth certificates for infants and young children may also speed the process.
Passengers must be patient while going through the checkpoint. TSA agents are there for passenger safety and security. Agents will not tolerate belligerent behavior, inappropriate jokes or threats. Unacceptable behavior will cause unnecessary delays and may result in meetings with law enforcement.
