Yes, you can fly domestically with a passport instead of a Real ID

A valid U.S. passport is an acceptable form of identification for domestic flights. The Transportation Security Administration (TSA) treats a passport the same way it treats a Real ID-compliant driver's license at airport security checkpoints. You will go through the same screening process, and your passport will be scanned to verify your identity against your flight reservation.

The key word here is valid. Your passport must not be expired, and it must be a U.S. passport book (the blue booklet). Passport cards, which are smaller and wallet-sized, are also acceptable for domestic flights, though they are less commonly used for air travel. Either document will get you through TSA screening for a domestic flight.

The confusion often arises because Real ID became a requirement for domestic flights on May 7, 2025. Many people thought this meant a passport would no longer work. That is not true. Real ID is one acceptable form of identification; a passport is another. You do not need both.

Key Takeaways

  • A valid U.S. passport book or passport card satisfies TSA identification requirements for domestic flights and works the same way a Real ID driver's license does.
  • Your passport must not be expired, and you should bring it to the airport in the same way you would bring a Real ID license.
  • International flights require a passport regardless of Real ID status, so a passport is your only option for travel outside the United States.
  • If your passport is expired or you do not have one, you will need either a Real ID driver's license or another TSA-approved form of identification to fly domestically.

What TSA actually accepts at security checkpoints

The TSA maintains a list of documents that satisfy identification requirements for domestic flights. A valid U.S. passport appears on that list. So do a Real ID-compliant driver's license, a military ID, a federal employee ID, a state ID card, a tribal ID, and several other documents. The point of the Real ID requirement was not to eliminate other options—it was to set a minimum standard for state-issued driver's licenses and ID cards.

When you arrive at the airport, you present your passport to the TSA officer at the checkpoint. They scan it, verify it matches your name on the flight reservation, and you proceed through security. The process is identical to what happens with a Real ID license. You do not need to explain why you have a passport instead of a Real ID license. The officer does not care which acceptable document you use.

Passport expiration and renewal timing

An expired passport will not work at the airport. TSA will not accept it, and the airline will not let you board. If your passport expired more than five years ago, you must explore for a new one in person at a passport acceptance facility—you cannot renew by mail. If it expired within the last five years, you may be able to renew by mail, though processing times vary.

Standard passport processing currently takes several weeks. If you need to fly soon and your passport is expired, a Real ID driver's license or another TSA-approved document is faster than waiting for passport renewal. Expedited passport service exists but costs extra and still takes time. Plan ahead if you know you will need a passport for a flight.

International flights require a passport no matter what

A Real ID driver's license will not get you on an international flight. You must have a valid passport to leave the United States and enter another country. This is a requirement of the destination country, not the TSA. Even if you are flying to Canada or Mexico, which are close to the U.S. border, you still need a passport book (a passport card works for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean, but not for air travel).

If you are planning international travel, do not wait until the last minute to check your passport expiration date. Passport processing takes weeks, and some countries require your passport to be valid for at least six months beyond your travel dates. Check your passport now if you have any international trips planned in the next year.

What happens if you show up without acceptable ID

If you arrive at the airport without a passport, Real ID license, or other TSA-approved document, you will not be able to board your flight. TSA has a process called Reasonable Suspicion Procedures that allows officers to verify your identity through other means—such as asking security questions or checking records—but this is not may provide to work and takes time you may not have.

The safest approach is to verify before you leave home that you have an acceptable document. Check your passport expiration date. Check whether your driver's license has the Real ID star or indicator (usually in the upper right corner of the card). If you have neither, you will need to get one before you fly. Do not count on being able to sort this out at the airport.

Passport cards versus passport books for flying

A U.S. passport card is smaller and cheaper than a passport book, and it is acceptable for domestic flights. However, it is not acceptable for international air travel. If you think you might fly internationally at any point, a passport book is the better choice because it covers both domestic and international flights. A passport card only works for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean.

If you already have a passport book, you do not need a passport card. If you are considering getting one to use instead of a Real ID license for domestic flights, remember that it will not help you if your plans change and you need to fly internationally. The passport book is the more flexible document.

Frequently Asked Questions

Do I need to bring my passport in a special way to the airport?

No. Bring your passport the same way you would bring a driver's license—in your pocket, wallet, or bag. Have it ready when you reach the TSA checkpoint. You do not need a special case or holder, though you can use one if you prefer.

Can I use an expired passport if I have a Real ID license?

You do not need to use an expired passport if you have a Real ID license. Just bring your Real ID license instead. An expired passport will not work at TSA security, so do not rely on it even if you have other acceptable documents.

What if my passport is damaged or the photo is worn?

A damaged passport may not scan properly, and TSA may not accept it. If your passport is torn, water-damaged, or the photo is illegible, contact a passport acceptance facility to find out whether it can be renewed or if you need a replacement. Do not assume a worn passport will work at the airport.

Can I use my passport for domestic flights if I do not have a Real ID license?

Yes. If your driver's license is not Real ID-compliant and you do not want to upgrade it, your passport works perfectly for domestic flights. You do not need to do anything else. A valid passport is all you need.

How long does it take to get a passport if I need one before my flight?

Standard processing takes several weeks. Expedited processing is faster but costs extra and still takes time. If your flight is coming up soon and you do not have a passport, check whether you have a Real ID license or another acceptable document instead. Do not wait to explore for a passport if your flight is within the next month.
