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. If you have a passport and no Real ID, you can use it to board any domestic flight within the United States.

This is the simplest answer: your passport works. You do not need a Real ID to fly domestically. You need one of several forms of federal identification, and a passport is one of them.

Key Takeaways

  • A valid U.S. passport is accepted at TSA checkpoints for domestic flights and counts as a federal ID, just like a Real ID driver's license.
  • A passport book or passport card both work for domestic air travel; either one is sufficient on its own.
  • You do not need to carry both your passport and your driver's license — the passport alone is enough to clear security.
  • International flights require a passport regardless of Real ID status, so a passport is your only option for travel outside the U.S.
  • If your passport is expired, it will not work for any flight; you must renew it before traveling.

What the TSA actually accepts at security checkpoints

The TSA maintains a list of acceptable forms of identification for domestic air travel. A valid U.S. passport appears on that list. So do a Real ID-compliant driver's license, a military ID, a state ID card, a tribal ID, and several other documents. The point of Real ID was to set a minimum standard for state-issued IDs — but it was never the only way to fly.

When you reach the TSA checkpoint, you hand over one form of federal identification. That document must be current (not expired) and must have a photo. A passport meets both requirements. The TSA agent will scan it, compare your face to the photo, and wave you through. The process is identical whether you show a Real ID or a passport.

Passport book versus passport card: which one works

The U.S. State Department issues two types of passports: the traditional passport book and the smaller passport card. Both are valid federal identification for domestic flights. Either one will work at the TSA checkpoint.

The passport card is wallet-sized and easier to carry than the book. However, the passport card can only be used for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean — not for air travel outside the U.S. If you think you might fly internationally, stick with the passport book. For domestic flights only, the card is fine.

Why you might still want a Real ID even if you have a passport

A passport works for flying, but it is not a replacement for a driver's license in everyday life. You still need a license to drive. If your state offers a Real ID driver's license, getting one means you have a document you can use for both driving and flying without carrying your passport everywhere.

A passport also takes weeks to renew if it expires. A Real ID driver's license renews on the same schedule as a regular license — usually every five to eight years depending on your state. If your passport expires while you are traveling, you cannot fly home without getting an emergency passport at a U.S. embassy or consulate. A Real ID license does not have that problem.

The choice is practical, not legal. You do not need a Real ID to fly. But having one means one less document to keep track of.

International flights and passport requirements

For any flight leaving the United States, a passport is required — Real ID status does not matter. You cannot board an international flight with only a driver's license, even if it is Real ID-compliant. A passport is the only document the U.S. government and foreign governments recognize for international air travel.

If you are flying internationally, make sure your passport is valid for at least six months beyond your travel dates. Many countries will not let you enter if your passport expires soon after you arrive. Check the entry requirements for your destination before you book.

What happens if your passport is expired

An expired passport will not work at the TSA checkpoint, even if it was valid when you booked your flight. The TSA requires your ID to be current. If your passport expired, you will be turned away at security.

Renewing a passport takes time. A standard renewal by mail takes four to six weeks. An expedited renewal takes two to three weeks and costs extra. An emergency passport at a passport acceptance facility can sometimes be issued the same day, but only if you are traveling within the next few days and can prove it. Plan ahead and renew before your trip.

Other federal IDs that work if you do not have a passport

If you do not have a passport and do not want to get one, you have other options. A Real ID-compliant driver's license works. So does a military ID, a state ID card, a tribal ID, a permanent resident card, or a U.S. Merchant Mariner credential. The TSA website lists all acceptable documents.

The important date for Real ID compliance at airport security was May 7, 2025. After that date, a standard (non-Real ID) driver's license will not work for domestic flights. If your license is not Real ID-compliant and you do not have a passport or other federal ID, you will need to get one before flying.

Frequently Asked Questions

Do I need to bring my passport in its original case or folder?

No. The TSA only needs to see the passport itself. You can carry it loose in your bag or pocket. The case or folder is optional and does not affect security screening.

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

No. An expired passport will not work at the TSA checkpoint. If your passport is expired, you must show a different form of current federal ID — such as a Real ID driver's license, military ID, or state ID card.

What if I lost my passport and my flight is in two weeks?

You have time to get an emergency passport. Visit a passport acceptance facility or passport agency in person with proof of your travel (your flight confirmation) and a birth certificate or other proof of citizenship. An emergency passport can be issued the same day or within a few days, depending on your location and how quickly you explore.

Does my passport card work for domestic flights?

Yes, your passport card is accepted at TSA checkpoints for domestic flights. However, if you plan to fly internationally, use your passport book instead — the card is only valid for land and sea travel to nearby countries.

If I use my passport to fly, do I still need to show my driver's license?

No. You only need to show one form of federal ID at the TSA checkpoint. A passport is sufficient on its own. You do not need to carry or show your driver's license.
