You do not need a passport to fly between U.S. states

A passport is not required for domestic flights — flights that stay within the United States. You can fly from New York to California, Texas to Florida, or any state to any other state with just a valid government-issued ID. The Transportation Security Administration (TSA) accepts several forms of ID at airport security checkpoints, and a passport is not the only option.

What you actually need is one form of acceptable identification. For most adults, this means a driver's license, state ID card, or military ID. If you do not have a driver's license, other documents work too. The key is that TSA must be able to verify your identity before you board.

Key Takeaways

  • A valid driver's license or state ID card is the standard form of identification for domestic flights and is accepted at every U.S. airport.
  • TSA accepts more than a dozen forms of ID for domestic travel, including military ID, passport, tribal ID, and even a school ID if you are under 18.
  • If you do not have a driver's license, you can use a passport, but it is not required — other government-issued IDs work just as well.
  • Real ID-compliant licenses (marked with a gold star or similar marking) are required for domestic flights starting May 7, 2025, in most states.

What forms of ID TSA accepts for domestic flights

TSA maintains a list of acceptable IDs for domestic air travel. A driver's license from any U.S. state or territory is the most common choice. A state-issued ID card (non-driver) works the same way. Military ID, including dependent ID cards, is accepted. A passport — U.S. or foreign — is accepted but not required.

Other acceptable documents include a tribal ID issued by a federally recognized tribe, an enhanced driver's license (available in some states), a merchant mariner card, or a U.S. Coast Guard ID. If you are under 18, a school ID paired with a report card or other school document can work. TSA also accepts a passport card (the wallet-sized version) in addition to a full passport book.

The point is straightforward: you have options. If you own a passport, you can use it. If you do not, a driver's license or state ID card will get you through security just as quickly.

Real ID requirements starting May 2025

Beginning May 7, 2025, TSA will require that your driver's license or state ID card meet Real ID standards for domestic flights. Real ID is a federal security standard that states must follow when issuing IDs. Most states have already updated their licenses to comply.

A Real ID-compliant license usually has a gold star, gold circle, or similar marking in the upper right corner. Check your license now — if it has this marking, you are already set. If it does not, you will need to visit your state's DMV to get a compliant license before May 2025. The process typically involves providing proof of identity, proof of residency, and your Social Security number, just as you would for a regular license renewal.

If you do not have a Real ID-compliant license by May 7, 2025, you can still fly domestically with a passport, passport card, military ID, or other TSA-approved document. But a driver's license will no longer work unless it meets the Real ID standard.

What happens if you arrive at the airport without acceptable ID

If you reach the security checkpoint without any of the documents TSA accepts, you will not be able to board your flight that day. TSA has a process called the 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 bring an acceptable ID. If you realize at home that you do not have one, contact your airline before heading to the airport. Some airlines may allow you to rebook on a later flight at no charge if you explain the situation. Do not count on this, though — it depends on the airline and how full the flight is.

Domestic versus international flights

The rules change if you are flying out of the United States to another country or arriving from abroad. For international flights, you must have a valid passport. A driver's license alone will not work. If you are flying to Canada, Mexico, or the Caribbean, you may also need additional documents such as a passport card, NEXUS card, or Enhanced Driver's License, depending on your destination.

If you are unsure whether your trip counts as domestic or international, check your flight itinerary. If both your departure and arrival airports are in the United States, it is domestic. If either airport is outside the U.S., you will need a passport.

Getting a Real ID-compliant license before May 2025

Visit your state's Department of Motor Vehicles website to find out what documents you need to bring. Most states require proof of identity (such as a birth certificate or passport), proof of your current address (such as a utility bill or lease), and your Social Security number. Bring originals or certified copies — photocopies usually do not count.

Processing times vary by state. Some states issue Real ID licenses on the spot; others mail them within two to four weeks. If you are renewing your license anyway, ask the DMV clerk to make sure your new license is Real ID-compliant. If you are just updating an existing license to Real ID status without renewing, the process is usually faster and sometimes free.

Do not wait until April 2025 to explore. DMVs often see long lines as important date approach, and you do not want to risk missing your flight because the office was too busy.

Frequently Asked Questions

Can I fly domestically with just a passport card instead of a full passport book?

Yes. A passport card is TSA-approved for domestic flights and is smaller and easier to carry than a full passport book. However, a passport card cannot be used for international air travel — only a full passport book works for flights leaving the U.S.

What if my driver's license is expired but I am renewing it?

An expired driver's license is still acceptable at TSA checkpoints for domestic flights. However, it is a good time to renew it and request a Real ID-compliant version at the same time, since the requirement takes effect in May 2025.

Do I need a passport if I am flying to Hawaii or Alaska?

No. Hawaii and Alaska are U.S. states, so flights there are domestic. A valid driver's license or state ID is all you need. A passport is not required unless you are connecting through a foreign country or flying to a U.S. territory outside the 50 states.

Can a foreign visitor fly domestically within the U.S. with their home country passport?

Yes. A valid foreign passport is acceptable to TSA for domestic flights within the United States. The passport must be unexpired and issued by a recognized government.

What if I lost my ID and my flight is tomorrow?

Contact your airline when ready and explain the situation. Some airlines may allow you to rebook without penalty. At the airport, TSA officers can attempt to verify your identity through other means, but there is no may provide this will work. Your best option is to get an emergency replacement ID from your state's DMV if they offer same-day service, or to postpone your flight.
