I'm 17 years old and I live in Southern CA and I was wondering if I could travel by plane to Washington state even though I don't have a visa. If so, what form of ID would be presentable to TSA? (I don't have a driver's license yet)
Anectodally, http://maphappy.org/2015/09/i-basically-used-a-costco-card-to-board-a-flight/ this person have boarded a flight with nothing but a Costco card.
A KPIX 5 undercover producer tested this security system, arriving at the San Francisco, San Jose and Oakland airports without official documentation. In every case, the producer was allowed to pass through security using a student ID and personal credit cards and was not subject to a secondary screening before gaining entrance to the terminal.
In the event you arrive at the airport without proper ID, because it is lost or at home, you may still be allowed to fly. TSA officers will request you present two other forms of ID bearing your name. One of the items must bear your name and other identifying information such as photo, address, phone number, social security number or date of birth.
There is no standard list of what alternate forms of ID are acceptable. Examples include: temporary paper driver's licenses, non-driver IDs, social security cards, birth certificates, marriage licenses and credit cards.
Also, if you are a Mexican citizen then you can get a Matricula Consular which is accepted by the TSA.
Travel within the United States requires no visa; as you are flying within the same country.
You will need proof of identification which is accepted by the TSA; however the site clearly states "Adult passengers 18 and over..."; for accompanied minors you don't need identification.
For unaccompanied minors (like yourself), you need to check with the airline. As by law there is no identification required from you, but there needs to be some proof that the person whose name is on the ticket is the person boarding the plane:
TSA does not require children under 18 to provide identification when traveling with a companion within the United States. Contact the airline for questions regarding specific ID requirements for travelers under 18.
So, its best to check with your airline what is required. They may even fast track your security clearances and give you priority boarding (as an unaccompanied minor).
