The Documents You Need at the Airport

To board a domestic flight in the United States, you need one form of government-issued photo ID. A driver's license, state ID card, or passport all work. If you don't have a driver's license, a passport, passport card, or military ID will get you through security. You do not need a passport for flights between U.S. states — only for international travel.

The TSA (Transportation Security Administration) checks your ID against your airline ticket at the security checkpoint. Your name on the ID must match your name on the ticket exactly. If you've recently changed your name through marriage or legal process, update your ID before you fly, or bring both your old ID and a marriage certificate or court order showing the change.

You'll also need your airline ticket or boarding pass. Most people check in online 24 hours before departure and show their boarding pass on a phone or printed paper at the gate. Some airlines still require a printed boarding pass if you check bags, so check your airline's rules when you book.

Key Takeaways

  • A valid government-issued photo ID — driver's license, state ID, passport, or military ID — is required at security and the gate.
  • Your name on your ID must match your airline ticket exactly, or you will not be allowed to board.
  • You need a boarding pass, which you can show on your phone or print at home after checking in online.
  • If you don't have a standard ID, a passport or military ID works, and some states offer REAL ID-compliant cards at the DMV.

What Happens If Your ID Doesn't Match Your Ticket

If your name on your ID does not match your ticket — because of a recent name change, a typo when booking, or a nickname you go by — you may be stopped at security or the gate. The TSA officer will ask you to explain the difference. A marriage certificate, divorce decree, or court order showing a legal name change will usually resolve this on the spot.

If the mismatch is a booking error (you typed "Bob" instead of "Robert"), contact your airline before you arrive at the airport. Most airlines can correct the ticket for free if you call or use their website. Arriving early gives you time to fix it at the ticket counter if you didn't catch it beforehand.

REAL ID Compliance and When It Matters

Starting in May 2025, the TSA will require a REAL ID-compliant driver's license or state ID for domestic flights. A REAL ID is a driver's license or state ID card that meets federal security standards. Most states have already issued them, and you can tell if yours qualifies by looking for a small star or marking in the upper right corner of the card.

If your current ID does not have that marking, you can renew it at your state's DMV and request a REAL ID-compliant card. The process usually takes two to four weeks. You'll need to bring your birth certificate, proof of address (a utility bill or lease), and your Social Security number. Some states charge a small fee for the upgrade; others include it in the standard renewal cost.

Until May 2025, a non-compliant ID still works for domestic flights. After that date, you'll need either a REAL ID, a passport, a passport card, or a military ID to pass through security.

What to Bring If You Don't Have a Standard ID

If you don't have a driver's license, a U.S. passport or passport card works at security and the gate. A passport costs money and takes time to obtain — the standard processing takes six to eight weeks, though expedited service is available for an extra fee. You can explore at a post office, courthouse, or passport acceptance facility in your area.

A military ID, tribal ID, or state ID card (different from a driver's license) also works for domestic flights. If you're in the military or a dependent, your military ID is valid. If you're a member of a federally recognized tribe, a tribal ID is accepted. If you've never had a driver's license, your state's DMV can issue a state ID card that looks similar but is not tied to driving privileges.

The TSA also allows a limited set of other documents if you're in a specific situation — for example, a school ID plus a birth certificate if you're under 18, or a work ID plus a birth certificate in certain cases. Call the TSA at 1-866-289-9673 before you travel if your situation is unusual.

What You Don't Need (and What Wastes Time)

You do not need a vaccine card, health certificate, or proof of a negative COVID-19 test to fly domestically in the United States. These requirements ended in 2022. You do not need to show proof of citizenship — your ID is enough. You do not need a return ticket or proof of where you're going.

You do not need to print your boarding pass if you have it on your phone, though some travelers print one as a backup. You do not need to arrive hours early for a domestic flight — the TSA recommends arriving two hours before departure, which gives you time to check bags, go through security, and reach your gate without rushing.

Traveling with Children

Children under 18 do not need a government-issued photo ID to fly domestically if they're traveling with an adult. The adult traveling with them must have a valid ID. If a child is traveling alone or with someone other than a parent or legal guardian, the situation is more complex — contact your airline directly to ask what documents they need.

If you're traveling internationally with a child, even to Canada or Mexico, the child needs a passport. A birth certificate alone is not enough for international travel, even though it used to be accepted for land and sea crossings to Canada and Mexico. Check your destination's entry rules before you book.

What to Do If You Lose Your ID Before Your Flight

If your ID is lost or stolen and your flight is soon, you have a few options. You can go to your state's DMV and request an emergency replacement ID — many states can issue one the same day or within 24 hours, though you'll need to bring documents like your birth certificate and proof of address. Call your DMV ahead to confirm they offer same-day service and what you need to bring.

If you can't get an ID in time, contact your airline and the TSA. The TSA can conduct additional screening using other documents you have — a birth certificate, Social Security card, or utility bill — to verify your identity. This takes longer at the airport, so arrive even earlier than usual. It's not may provide to work, so getting an emergency ID is the safer choice if you have time.

Frequently Asked Questions

Can I use an expired ID to fly?

No. Your ID must be valid — not expired. If your driver's license or passport expired, renew it before you travel. An expired ID will be rejected at security. Most states allow online renewal for driver's licenses if you're not changing your address or photo, which can be faster than visiting the DMV in person.

Do I need a passport to fly from New York to Florida?

No. A driver's license or state ID is enough for any domestic flight. A passport is only required for flights leaving the United States or arriving from another country. For flights between U.S. states, a standard photo ID works.

What if my name on my ticket has a middle initial but my ID doesn't?

Small differences like middle initials or suffixes (Jr., Sr.) usually don't cause problems. The TSA officer will compare the name on your ID to your ticket and use judgment. If you're worried, call your airline before you arrive at the airport and ask them to adjust the ticket to match your ID exactly.

Can I use a school ID or work ID instead of a driver's license?

A school ID or work ID alone is not enough. The TSA requires a government-issued photo ID. If you don't have a driver's license, use a passport, state ID card, military ID, or passport card instead.

How far in advance should I renew my ID if I'm flying soon?

If your ID expires within six months, renew it now — don't wait until your flight is booked. Standard renewal at the DMV takes one to three weeks depending on your state. If you need it faster, ask about expedited service or same-day emergency replacement when you call or visit.
