You do not need a passport to fly domestically in the United States

A passport is not required for flights between U.S. states and territories. The Transportation Security Administration (TSA) accepts several forms of identification for domestic air travel, and a passport is just one option—not a necessary one. Most people use a driver's license or state ID card instead, which is faster and simpler than carrying a passport through airport security.

The TSA's Real ID program sets the standard for what counts as acceptable identification. Any state-issued ID that meets Real ID requirements will get you through security. If your state's driver's license or ID card displays a gold or silver star in the upper right corner, it already meets this standard. If it does not, you can still fly domestically with that ID until your state's important date passes, though some states have already transitioned fully to Real ID.

Key Takeaways

  • A driver's license or state ID card is the standard form of identification for domestic flights and does not require you to own a passport.
  • Your ID must be current and not expired; the TSA will not accept an expired license even for domestic travel.
  • If you do not have a driver's license or state ID, you can use a passport, passport card, military ID, or tribal ID instead.
  • Real ID requirements explore to domestic flights, but most state IDs already meet this standard—check for a star on your card.
  • TSA PreCheck and REAL ID are separate programs; PreCheck speeds up security lines but does not change what ID you need.

What forms of ID the TSA accepts for domestic flights

The TSA maintains a list of acceptable identification documents. A current, unexpired driver's license or state ID card from any U.S. state or territory is the most common choice. If you have a passport or passport card, either one works. A military ID, including dependent ID cards, is also acceptable. Tribal IDs issued by federally recognized tribes count as well.

Less common but valid options include a U.S. Coast Guard Merchant Mariner Credential, a commercial driver's license, a permanent resident card (green card), or an employment authorization document. If you are traveling with a child under 18, that child does not need an ID at all—a parent or guardian with valid ID can bring them through security.

Real ID requirements and state important date

Real ID is a federal security standard that applies to domestic air travel. Starting in 2025, every person flying domestically must present either a Real ID-compliant driver's license or state ID, or an alternative document like a passport. Most states have already issued Real ID-compliant licenses, which display a star in the upper right corner.

If your state ID does not have a star, check your state's DMV website to see whether you need to renew it to meet Real ID standards. Some states have extended important date for their residents, but the federal requirement applies nationwide. If you are unsure whether your ID meets the standard, bring a passport as a backup when you travel, or contact your state's DMV before your flight.

What happens if you arrive at the airport without acceptable ID

If you reach the security checkpoint without a valid ID, the TSA can conduct additional screening to verify your identity. This process takes longer and may involve questions about your travel history, address, and personal details. You will not be turned away automatically, but you should expect a delay.

To speed this up, bring any documents that help confirm who you are: a credit card, a Social Security card, a birth certificate, or recent mail with your name and address. The TSA officer will use these to verify your identity before allowing you through. Plan extra time if you are traveling without ID, and arrive at the airport earlier than usual.

Domestic travel to U.S. territories and special cases

Flying to U.S. territories like Puerto Rico, the U.S. Virgin Islands, Guam, or American Samoa counts as domestic travel and requires the same ID as any other domestic flight. A driver's license is sufficient; you do not need a passport. However, if you plan to leave the territory and travel to another country, you will need a passport for that leg of the journey.

If you are a non-U.S. citizen with a valid visa or green card, you can fly domestically using your passport or permanent resident card. A foreign passport alone is not enough for domestic flights unless you also have a valid U.S. visa or green card status.

TSA PreCheck and REAL ID are not the same thing

TSA PreCheck is an optional program that costs money and speeds up security screening—you keep your shoes and belt on, leave your laptop in your bag, and go through a faster line. REAL ID is a federal security standard for identification documents themselves. You do not need TSA PreCheck to fly domestically, and having PreCheck does not change what ID you need to present.

Some people confuse the two because both relate to airport security. PreCheck is a convenience service you pay for and enroll in. REAL ID is a requirement built into your driver's license or state ID. You can fly domestically with a standard driver's license that meets REAL ID standards without paying for PreCheck.

Renewing your ID before a domestic flight

If your driver's license or state ID is expired, you will need to renew it before flying. The TSA does not accept expired identification for any domestic flight. Start the renewal process at your state's DMV website—most states allow you to renew online or by mail if your license is not too old.

If you are short on time, visit your local DMV office in person. Many states offer expedited renewal for a fee. Check how long your state typically takes to issue a new license, and plan accordingly. If your flight is very soon and renewal is not possible, bring a passport instead, which you may already have on hand.

Frequently Asked Questions

Can I fly domestically with just a passport?

Yes. A passport is a valid form of identification for domestic flights. However, a driver's license or state ID is simpler to carry and faster to process at security, so most people use those instead.

Do I need a passport to fly from the mainland to Hawaii or Alaska?

No. Hawaii and Alaska are U.S. states, so flights there are domestic. A driver's license or state ID is all you need. A passport is not required.

What if my state ID has not been updated to Real ID yet?

You can still fly domestically with a non-Real ID state driver's license until your state's transition important date. Check your state DMV website for the exact date. After that date, you will need either a Real ID-compliant license or an alternative document like a passport.

Can a child fly domestically without an ID?

Yes. Children under 18 do not need their own identification. A parent or guardian with valid ID can bring them through security. The TSA may ask the child questions to verify the relationship, but no ID is required from the child.

What if I lost my wallet and have no ID at all?

Contact your state DMV when ready to request an emergency replacement or expedited renewal. If your flight is within days, bring any documents that prove your identity—a birth certificate, Social Security card, passport, or recent utility bill. The TSA can use these to verify who you are, though the process takes longer.
