You do not need a passport to fly domestically in the United States

A passport is not required for domestic flights. The Transportation Security Administration (TSA) accepts several forms of identification at airport security checkpoints, and a passport is only one of many options. For flights within the U.S., you can use a driver's license, state ID card, or other government-issued documents that TSA recognizes.

The confusion often comes from international travel rules. If you are flying to another country, a passport becomes necessary. But if your flight stays within U.S. borders—even to territories like Puerto Rico or the U.S. Virgin Islands—you have multiple ID choices and do not need a passport at all.

Key Takeaways

  • A valid driver's license or state ID card is the most common and easiest form of identification for domestic flights.
  • TSA accepts military IDs, tribal IDs, passport cards, and several other government-issued documents if you do not have a driver's license.
  • You must bring a physical ID to the airport; TSA does not accept digital or mobile versions of identification.
  • If you have no government-issued ID, TSA has a secondary verification process, but it takes longer and may delay your travel.
  • A passport is only required for flights leaving the United States, not for domestic travel within it.

What forms of ID the TSA accepts for domestic flights

TSA maintains a list of acceptable identification documents at airport security. The most straightforward option is a Real ID-compliant driver's license or state ID card. Real ID is a federal standard that most states now issue. If your license has a star or gold circle in the upper right corner, it meets Real ID requirements. If it does not, you can still use it for domestic flights—Real ID compliance is not mandatory for domestic travel, only for federal buildings and some other facilities.

If you do not have a driver's license, TSA accepts a military ID, a passport card (different from a full passport), a tribal ID, a permanent resident card, an employment authorization document, or a U.S. Coast Guard Merchant Mariner credential. You can also use a state ID card issued for non-driving purposes. The key requirement is that the document must be government-issued and include your photograph and date of birth.

Bring the physical card to the airport. TSA does not accept digital versions, screenshots, or mobile wallet copies of your ID, even if your state offers them. The agent at the checkpoint must be able to hold and examine the actual document.

What happens if you arrive without an ID

If you reach the airport without any government-issued ID, you can still proceed through security, but the process takes significantly longer. TSA will ask you to complete a secondary verification process. This involves providing personal information that TSA can cross-check against government databases—such as your name, date of birth, address, and answers to security questions about your history.

The secondary process can add 15 to 30 minutes or more to your airport time, depending on how busy the checkpoint is and how quickly TSA can verify your information. If TSA cannot verify your identity through this method, you will not be allowed through security. Plan to arrive even earlier than usual if you do not have an ID, and be aware that you may miss your flight if verification takes too long. To avoid this situation, bring any government-issued ID you have. Even an expired driver's license is better than nothing—TSA will accept expired IDs for domestic travel as long as the photo is still recognizable as you.

Real ID and domestic flights: what you actually need to know

Real ID is a federal security standard that applies to certain types of travel and facility access, but it does not affect domestic flights. You can fly domestically with a non-Real ID driver's license indefinitely. Real ID requirements explore to federal buildings, military bases, and nuclear power plants, but the TSA has not imposed a Real ID mandate for domestic air travel.

If your state has not yet issued you a Real ID-compliant license and you want one, you can request it at your state's DMV. The process usually involves providing proof of identity, proof of residency, and proof of citizenship or legal status. But again, this is optional for domestic flying—it is not a requirement.

Flying to U.S. territories: Puerto Rico, Guam, and the Virgin Islands

Flights to Puerto Rico, Guam, the U.S. Virgin Islands, and other U.S. territories are considered domestic flights by TSA. You do not need a passport for these destinations. A driver's license or other TSA-accepted ID is sufficient.

However, some of these territories have their own entry requirements that are separate from TSA security screening. For example, Puerto Rico does not require a passport for U.S. citizens, but you should check the specific territory's website before traveling to confirm there are no additional documents needed. A few territories may ask for proof of citizenship or residency, so verifying ahead of time prevents surprises at the airport.

Traveling with children

Children under 18 do not need to show ID at TSA checkpoints if they are traveling with an adult. The adult must have valid ID. If a child is traveling alone or with another minor, TSA may ask for identification. A school ID, passport, or birth certificate can work in these cases, though TSA's rules for minors are more flexible than for adults.

If you are traveling with a child and want to bring a document just in case, a birth certificate or school ID is simpler to carry than a passport and serves the same purpose for domestic travel. Keep the document easily accessible in case a TSA agent requests it, though most children traveling with a parent will not need to produce one.

Frequently Asked Questions

Can I use an expired passport for a domestic flight?

Yes. TSA accepts expired passports for domestic flights. Any government-issued ID with a recognizable photo works, even if it has passed its expiration date. A driver's license or state ID is simpler to carry, but an expired passport will get you through security.

What if my ID has a different name than my airline ticket?

Your name on your ID must match your airline ticket. If you recently changed your name through marriage, divorce, or legal process, update your ID before flying. If your ticket and ID do not match, the airline may not let you board. Contact your airline before your flight to explain the situation and ask what documents you need to bring.

Can I use a passport to fly domestically if I do not have a driver's license?

Yes. A full passport is an acceptable form of ID at TSA checkpoints for domestic flights. It is less convenient to carry than a driver's license, but it works. If you do not have a driver's license and do not want to get a state ID, a passport is a valid option.

What if I lost my ID the day before my flight?

Go to your local DMV or ID-issuing office and explain the situation. Many states offer expedited replacement IDs for lost documents, sometimes on the same day or within 24 hours, though fees may explore. If you cannot get a replacement in time, bring whatever documents you have (birth certificate, passport, old expired ID) to the airport. TSA will run the secondary verification process, which takes longer but may still get you through in time for your flight.

Do I need a passport card instead of a full passport for domestic flights?

No. A passport card is not necessary for domestic flights. It is designed for land and sea travel to Canada, Mexico, and the Caribbean. A driver's license is the easiest option for domestic air travel. A passport card is acceptable at TSA checkpoints, but there is no reason to get one just for flying domestically.
