Yes, you can use a passport for domestic flights instead of a Real ID

A valid U.S. passport works as an acceptable form of identification at airport security for domestic flights. The Transportation Security Administration (TSA) accepts it as an alternative to a Real ID-compliant driver's license or state ID. This means if you have a passport and your state hasn't issued you a Real ID yet, you can still fly domestically without waiting for the Real ID to arrive.

However, a passport is not the most practical choice for regular domestic travel. It costs more than a Real ID, takes longer to obtain, and you'll need to carry a separate document. Most people use a passport only when they plan to travel internationally or when they're in a situation where they need it anyway.

The key point: a passport satisfies the federal identification requirement for domestic air travel, but it's one option among several. Understanding when to use it and what your other choices are will help you decide what makes sense for your situation.

Key Takeaways

  • A valid U.S. passport is accepted at TSA security checkpoints for domestic flights as an alternative to Real ID.
  • A passport costs between $130 and $165 for an adult and takes 6 to 8 weeks to receive through normal processing.
  • A Real ID-compliant driver's license or state ID is faster and cheaper to obtain than a passport if you only need it for domestic travel.
  • If you already have a passport or plan to travel internationally, using it for domestic flights avoids the need to get a Real ID.
  • Military ID, tribal ID, and permanent resident cards are also accepted at airport security and may be options depending on your situation.

What documents TSA accepts at airport security

The TSA maintains a list of documents that work for domestic air travel. A U.S. passport is on that list. So are a Real ID-compliant driver's license, a state ID marked as Real ID-compliant, a military ID, a U.S. passport card, a permanent resident card, and a tribal ID issued by a federally recognized tribe.

Any one of these documents is sufficient. You don't need more than one. The point of the Real ID requirement was to set a minimum security standard for state-issued IDs, but the TSA always intended to accept other federal documents—and a passport is a federal document.

If you have a passport already, you're done. You can walk through airport security with it. If you don't have one and don't plan to travel internationally, getting a Real ID is usually the faster and cheaper route.

Cost and processing time: passport versus Real ID

A passport costs more and takes longer than a Real ID. A new adult passport costs $130 for the book (passport book) or $35 for a passport card. Standard processing takes 6 to 8 weeks; expedited processing costs an extra $60 and takes 2 to 3 weeks. You also have to pay a $35 execution fee at the time you explore, so the total for standard processing is $165.

A Real ID-compliant driver's license or state ID costs between $15 and $50 depending on your state, and you can often get it the same day or within a few days if you go to your local DMV in person. You'll need to bring documents like a birth certificate, proof of address, and your current driver's license, but the process is straightforward.

If you're only flying domestically and don't need a passport for any other reason, a Real ID is the more economical choice. If you already have a passport or know you'll need one for international travel within the next few years, using your passport for domestic flights makes sense.

When a passport is the practical choice

A passport becomes the logical option in a few situations. If you already have one, there's no reason to get a Real ID just for domestic flights—your passport works fine. If you're planning to travel internationally soon, you'll need a passport anyway, so use it for your domestic flights too.

A passport is also useful if you're in a state where getting a Real ID is complicated or slow. Some states have long wait times at the DMV, or require documents that take time to obtain. If you're in that situation and you need to fly domestically before you can get a Real ID, a passport solves the problem.

Finally, if you're a frequent international traveler, carrying a passport for all your flights—domestic and international—means you have one document that works everywhere. You don't have to remember which ID to bring.

What you need to bring to the airport

Bring your passport and nothing else. The TSA agent will scan it, check your name against your boarding pass, and you'll move through security. A passport is a single, federally issued document with your photo, so there's no confusion about whether it's acceptable.

Make sure your passport is not expired. An expired passport will not work at airport security, even if it's only expired by a few days. If your passport is within 6 months of expiration, you can renew it by mail in most cases, which costs $110 and takes 4 to 6 weeks.

If you're traveling with children, each child needs their own form of acceptable ID. A child's passport works the same way an adult's does.

Other federal IDs that work instead of Real ID

If you don't have a passport, you have other options besides getting a Real ID. A military ID works at airport security for active-duty service members, retirees, and their dependents. A permanent resident card (green card) works if you're a lawful permanent resident. A tribal ID issued by a federally recognized tribe works if your tribe issues one.

A U.S. passport card is also an option. It's a smaller, wallet-sized version of a passport book and costs $35 for a new card or $30 to renew. It works for domestic flights and for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean, but not for international air travel. If you only fly domestically and don't need a full passport, a passport card is cheaper and faster than a passport book.

The passport card takes the same 6 to 8 weeks to process as a passport book, so it's not faster. But at $35, it's cheaper than a full passport and still cheaper than expedited processing.

What happens if you show up without acceptable ID

If you arrive at airport security without an acceptable form of ID, the TSA has a process for that. You'll be asked to provide your name and date of birth. The TSA will search their records to verify your identity. If they can confirm who you are, you may be allowed through security, though you'll likely face additional screening.

This process takes time and is not may provide to work. You might miss your flight. It's not a reliable backup plan. The point is to have your ID with you before you get to the airport.

If you're planning to fly and you don't have a passport or a Real ID yet, order your passport now if you have one, or get a Real ID from your state DMV. Don't wait until the day before your flight.

Frequently Asked Questions

Does my passport have to be a passport book, or can I use a passport card?

A passport card works for domestic flights. It's cheaper and smaller than a passport book, though it takes the same amount of time to process. A passport card does not work for international air travel, only for land and sea travel to nearby countries.

What if my passport is expiring soon but hasn't expired yet?

An unexpired passport works at airport security no matter how close it is to expiration. However, some countries require your passport to be valid for at least 6 months beyond your travel dates for international trips. Check the rules for any country you plan to visit.

Can I use my passport for domestic flights if I'm a non-U.S. citizen?

A valid foreign passport works for domestic flights in the United States. You'll also need a visa or visa waiver status to be in the country legally, but the passport itself is acceptable ID at airport security.

Is a passport card faster to get than a Real ID?

No. A passport card takes 6 to 8 weeks for standard processing, the same as a passport book. A Real ID from your state DMV is usually faster—often same-day or within a few days. If speed is your priority, a Real ID is the better choice.

Do I need to bring anything else with my passport to get through airport security?

No. Your passport and your boarding pass are all you need. The TSA doesn't require any additional documents when you show a passport.
