You do not need a passport for domestic flights in the US

A passport is not required to fly between US states. The Transportation Security Administration (TSA) accepts a standard driver's license or state ID card as proof of identity at airport security checkpoints. If you don't have a driver's license, you have other options that work just as well — you do not need to obtain a passport for domestic travel.

The confusion often comes from international travel, where a passport is mandatory. Domestic flights operate under different rules. As long as you have one of the accepted forms of identification, you can board a flight within the United States without a passport.

Key Takeaways

  • A valid driver's license or state ID card is the standard form of identification for domestic flights and is accepted at every US airport.
  • If you don't have a driver's license, the TSA accepts military ID, passport cards, tribal IDs, and several other documents listed on their website.
  • Real ID-compliant licenses became required for domestic flights in May 2025, so check whether your state ID meets the current standard.
  • You can still fly with a non-compliant ID if you also bring a secondary document like a birth certificate or Social Security card, though this takes longer at security.
  • Children under 18 do not need to show ID on domestic flights if traveling with an adult, but the adult must have valid identification.

What counts as valid ID for domestic flights

The TSA maintains a list of documents it accepts at security checkpoints. A driver's license or state ID card is the fastest option. If you don't have either, you can use a military ID, a passport card (which is different from a full passport and costs less), a tribal ID issued by a federally recognized tribe, or an enhanced driver's license.

Less common but still valid options include a US passport, a permanent resident card, a US merchant mariner credential, or a border crossing card. You can also use a state-issued ID for people with disabilities. The document must not be expired, though the TSA allows a grace period for IDs that expired during the COVID-19 pandemic — check the TSA website for current rules on expired documents.

If you have none of these documents, you can still fly, but the process is slower. You'll go through additional screening, which can add 15 to 30 minutes to your airport arrival time. You'll need to bring secondary documents like a birth certificate, Social Security card, or utility bill with your name and address.

Real ID compliance and what changed in 2025

Starting in May 2025, the TSA began enforcing Real ID standards for domestic flights. This means your driver's license or state ID must meet federal security requirements. Most states have already updated their licenses to be Real ID-compliant, but not all. You can check whether your state's ID meets the standard by looking for a star or marking on your license — the TSA website has a state-by-state guide showing what that marking looks like.

If your ID is not Real ID-compliant, you have two options. You can renew your license through your state's DMV and request a Real ID-compliant version, which usually takes a few weeks. Or you can continue flying with your current ID by bringing a secondary document — a birth certificate, passport, or Social Security card — which requires extra screening at security.

The Real ID requirement applies only to domestic flights. If you're flying internationally, a passport is still required regardless of Real ID status.

How to get a Real ID-compliant license

Contact your state's Department of Motor Vehicles (DMV) or equivalent agency — the name varies by state. You can usually start the process online by scheduling an appointment or requesting a form. When you go in person, bring documents that prove your identity, Social Security number, and current address. Most states require an original birth certificate or passport, a Social Security card or tax return, and a utility bill or lease.

Processing times vary by state, typically ranging from two to six weeks. Some states offer expedited processing for an additional fee. If you're flying soon and your current ID is not compliant, bring a secondary document to the airport instead of waiting for a new license.

Flying with children and minors

Children under 18 do not need to show ID on domestic flights if they are traveling with an adult. The adult must have valid identification, but the child does not. This applies whether the child is a US citizen or not.

If a child is traveling alone or with someone other than a parent or legal guardian, some airlines require additional documentation, such as a notarized letter of consent from the parent. This is an airline policy, not a TSA requirement, so check with your specific airline before traveling.

What to bring to the airport

Arrive at the airport with your ID in hand. Have it ready when you reach the TSA checkpoint — you'll need to show it before you can proceed through security. If your ID is expired or not Real ID-compliant, bring your secondary documents (birth certificate, Social Security card, or utility bill) as well.

Keep your ID easily accessible in a pocket or bag you can reach quickly. The TSA agent will scan or examine it, so make sure it's not damaged or difficult to read. If your ID is damaged or the photo is no longer recognizable, renew it before your flight to avoid delays.

Frequently Asked Questions

Can I fly with just a photo of my ID on my phone?

No. The TSA requires a physical ID document, not a digital copy. You must bring the actual card or document to the checkpoint. Some airlines are testing digital ID options, but they are not yet standard across US airports.

What if I lost my ID right before my flight?

You can still fly by going through additional screening with secondary documents like a birth certificate or Social Security card. This process takes longer — plan for an extra 15 to 30 minutes at security. Contact your airline before arriving at the airport to let them know your situation.

Do I need a passport card instead of a regular driver's license?

No. A passport card and a driver's license are equally valid for domestic flights. A passport card is useful only if you plan to travel internationally by land or sea to Canada, Mexico, or the Caribbean. For domestic flights alone, your driver's license is sufficient.

Can I use an expired ID if it's only been expired for a few months?

The TSA's rules on expired IDs change periodically. Check the TSA website before your flight to see the current policy. During the COVID-19 pandemic, expired IDs were accepted with a grace period, but that grace period has ended. Most expired IDs are no longer accepted, so renew yours if it has passed the expiration date.

What if my state hasn't issued Real ID-compliant licenses yet?

As of 2025, all 50 states and US territories have Real ID-compliant licenses available. If your state is still in transition, you can request a compliant version at your DMV. If you can't get one before your flight, bring a secondary document to the airport for additional screening.
