I am traveling with children, do my children need to have a photo ID or their birth certificate to travel?

All passengers who are 18 years of age and older must present a government issued photo ID. If your children are less than 18 years of age they will not need to have a photo ID or birth certificate to travel within the continental United States. Beginning October 1, 2021 you will be required to have a passport or REAL ID to board federally regulated domestic flights.
