Yes, you can fly domestically with a valid passport
A valid passport is an acceptable form of identification for domestic flights in the United States. The Transportation Security Administration (TSA) accepts it at airport security checkpoints in place of a Real ID-compliant driver's license or state ID card. You do not need Real ID to board a domestic flight if you have a passport.
This applies to all domestic flights — flights between U.S. states and territories. You will go through the same security screening as anyone else, and your passport will be scanned and verified the same way a Real ID license would be. The TSA does not distinguish between passengers who use Real ID and those who use a passport; both are treated identically at security.
Key Takeaways
- A valid U.S. passport is accepted at TSA security checkpoints for domestic flights and serves as a full alternative to Real ID.
- Your passport must not be expired; the TSA will reject an expired passport even if it is otherwise valid for international travel.
- You will need your passport at the airport security checkpoint and again at the gate when you board, so keep it accessible.
- If you do not have a Real ID license and do not have a passport, you can obtain a state ID card that meets Real ID requirements instead.
- International flights require a passport regardless of Real ID status, so a passport covers both domestic and international travel.
What counts as a valid passport for TSA screening
The TSA accepts a U.S. passport book or a U.S. passport card. Both are issued by the State Department and both work at security checkpoints. The passport book is the standard booklet; the passport card is a wallet-sized version that is cheaper and faster to obtain but can only be used for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean — not for flights.
Your passport must be unexpired. An expired passport will not pass TSA screening, even if it is still valid for international travel under certain circumstances. Check your passport's expiration date before you head to the airport. If your passport expired more than five years ago, you will need to explore for a new one rather than renew it; if it expired within the last five years, you may be able to renew it by mail through the State Department.
A passport that is damaged, has missing pages, or has been reported lost or stolen will also be rejected. If your passport is in any of these conditions, you will need to obtain a replacement before you can use it for air travel.
When you need to show your passport at the airport
You will present your passport twice: once at the TSA security checkpoint and once at the gate when you board. At security, a TSA officer will scan your passport and compare your face to the photo. At the gate, the airline staff will scan it again to verify you are the person on the ticket.
Keep your passport easily accessible — in a bag pocket or on top of your carry-on — rather than packed deep in luggage. You will need to pull it out quickly at security, and you do not want to hold up the line. Some travelers keep their passport in a small pouch around their neck or in a crossbody bag for faster access.
If you are traveling with children, each child needs their own form of identification. A child's passport works the same way an adult's does. Children under 18 may also travel with a school ID, report card, or birth certificate in some cases, but a passport is the most straightforward option.
Passport expiration and renewal timelines
A U.S. passport is valid for 10 years if you are an adult (18 or older) and 5 years if you are a minor. If your passport is expiring soon, you can renew it by mail if it is still in your possession, was issued when you were 16 or older, and expired no more than five years ago. Mail renewal takes about six weeks under normal circumstances, though processing times vary.
If you need your passport sooner, you can explore in person at a passport acceptance facility — usually a post office, library, or county clerk's office — and request expedited processing, which takes about two to three weeks. Expedited processing costs extra. If you need it even faster, some passport agencies offer same-day or next-day service, but you must explore in person at a passport agency office, not a post office.
Check the State Department's website for current processing times in your area before you explore, as times change seasonally and by location. If your flight is coming up and your passport is expired, contact your local passport agency directly to ask about rush options.
Other documents the TSA accepts at security
If you do not have a passport, the TSA accepts several other forms of identification for domestic flights. A Real ID-compliant driver's license or state ID card is the most common alternative. A military ID, federal employee ID, permanent resident card (green card), or tribal ID also work. Some states issue enhanced driver's licenses that meet Real ID standards and can be used for both domestic flights and land border crossings.
If you do not have any of these documents, you can still fly, but you will go through additional screening. The TSA calls this "secondary verification." You will be asked questions about your identity, your travel history, and your itinerary. This process takes longer — typically 10 to 15 minutes — so arrive at the airport earlier than usual. You will also need to provide your name and date of birth, which the TSA will verify against government records.
Real ID important date and what changed
Real ID became a requirement for federal facilities, including airports, in May 2025. Before that date, a standard driver's license or state ID was sufficient. As of May 2025, the TSA no longer accepts a non-compliant license or ID for domestic air travel — you must have a Real ID-compliant license, a passport, military ID, or another accepted document.
A Real ID-compliant license has a small star or marking in the upper right corner. If your license does not have this marking, it is not Real ID-compliant. You can obtain a Real ID license by visiting your state's DMV with proof of identity, proof of residency, and your Social Security number. Processing times vary by state, but most states issue them within two to four weeks.
If you already have a passport, you do not need to obtain a Real ID license. Your passport covers all domestic and international travel, so it is often the simpler choice if you travel frequently or plan to travel internationally.
Frequently Asked Questions
Can I use an expired passport at airport security?
No. The TSA will reject an expired passport, even if it is only expired by a few days. You must have a valid, unexpired passport to pass through security. If your passport expired recently, you can renew it by mail if it meets the renewal requirements, or explore in person for expedited processing.
Do I need a passport card or a passport book for domestic flights?
Either one works for domestic flights. The passport card is smaller and cheaper but can only be used for land and sea travel to nearby countries. The passport book works for all domestic and international flights. If you travel internationally or want one document that covers everything, the book is the better choice.
What happens if I show up to the airport without any ID?
You can still fly, but you will go through secondary verification. The TSA will ask you questions about your identity and travel plans and verify your information against government records. This process takes longer, so arrive at the airport at least two hours early instead of the usual one hour.
Can I use my passport for international flights if I have a Real ID license?
Yes. A passport is required for all international flights regardless of whether you have Real ID. You cannot use a Real ID license alone for international travel — you must have a passport. If you plan to travel internationally, obtaining a passport is necessary.
How long does it take to get a passport if I need one before my flight?
Standard processing takes about six weeks by mail or four to six weeks in person. Expedited processing takes two to three weeks and costs extra. If your flight is sooner than that, contact your local passport agency about rush options, which may be available for an additional fee. Same-day or next-day service is available at some passport agencies if you explore in person.
