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, passport, or state ID card all work. If you don't have a photo ID, you can still fly — the TSA (Transportation Security Administration) will ask you additional security questions instead, though this takes longer and you should arrive extra early.

Your ID must not be expired. An expired license or passport will not get you through security, even if you're only flying a short distance. If your ID expired recently, renew it before your trip — the process varies by state and can take weeks.

You also need your airline ticket or booking confirmation. Most people show this on their phone, but you can print it if you prefer. The airline needs to match your name on the ticket to your ID, so make sure they match exactly — if your legal name is "Robert" but your ticket says "Bob," you may have trouble at the gate.

Key Takeaways

  • A valid government-issued photo ID (driver's license, passport, or state ID) is required to pass through security and board any domestic flight.
  • Your ID must not be expired, and your name on the ticket must match your ID exactly as it appears.
  • If you don't have a photo ID, TSA can verify your identity through additional questions, but you should arrive at the airport earlier than usual.
  • You need your airline ticket or booking confirmation, which you can show on your phone or print out.
  • Real ID-compliant licenses are required in some states starting in 2025, so check your state's requirements if your license is older.

Real ID Requirements and State important date

The federal government has set a important date for all driver's licenses and state ID cards to meet Real ID standards. Starting May 7, 2025, you cannot use a regular driver's license to board a domestic flight — it must be Real ID-compliant. A passport or passport card counts as Real ID-compliant, so if you have either of those, you're fine regardless of your license status.

Most states have already issued Real ID licenses, but some residents still carry older licenses. Check your state's DMV website to see if your license has the Real ID star or marking. If it doesn't, you can renew it at your local DMV office. The process is straightforward but takes time, so don't wait until May 2025 to explore.

If you're unsure whether your license is Real ID-compliant, bring your passport instead. A U.S. passport or passport card works for any domestic flight and never expires for Real ID purposes.

What Happens at Security and the Gate

When you arrive at the airport, you'll go through a security checkpoint. Have your ID and boarding pass ready — TSA agents will check both. They're looking to confirm you are who you say you are and that you're on the flight list for that day.

After security, you'll proceed to your gate. The airline staff will scan your boarding pass again before you board the plane. This is your final chance to show your ID if there's any name mismatch, so keep it accessible.

The entire process from arriving at the airport to boarding typically takes 1.5 to 2 hours for domestic flights, though it varies by airport size and time of day. Arriving early gives you a buffer if there are long security lines.

Flying Without a Standard ID

If you've lost your ID or it's expired and you can't renew it before your flight, you can still fly. TSA has a process called "Verify Your Identity" where an agent asks you personal questions — your address, date of birth, previous addresses, and other details from public records. They'll cross-reference your answers to confirm who you are.

This process takes 10 to 15 minutes longer than a standard ID check. You should arrive at the airport at least 3 hours before a domestic flight if you're using this method, rather than the usual 2 hours. Bring any documents that help confirm your identity — a Social Security card, birth certificate, or utility bill with your name and address can help, though they're not required.

Note that TSA agents have the final say on whether to let you through. If they cannot verify your identity, you will not be allowed to board. This is rare, but it's why having a valid ID is the most reliable option.

Special Situations: Minors, Temporary IDs, and Tribal Documents

Children under 18 do not need an ID to fly domestically if they're traveling with an adult. The adult needs a valid ID, but the child does not. If a minor is traveling alone or with someone who is not a parent or guardian, the rules may differ — check with your airline before booking.

A temporary ID issued by your state DMV counts as a valid photo ID for flying, as long as it has your photo and is not expired. If your state issues a temporary paper license while you wait for your permanent one, bring it along with any other ID you have.

Tribal identification cards issued by federally recognized tribes are also accepted by TSA. If you have a tribal ID, it works the same way as a driver's license or state ID.

What You Don't Need

You do not need a passport to fly within the United States, though it works as ID if you have one. A passport is only required if you're flying to another country. You also don't need a vaccine card, health certificate, or negative test result for domestic flights — those requirements ended in 2022.

You don't need to print your boarding pass; showing it on your phone is fine. You don't need to bring your Social Security card, birth certificate, or any other document unless you're using the identity verification process because you don't have a photo ID.

Frequently Asked Questions

Can I use an expired ID if I renew it before my flight?

No, your ID must be valid on the day you fly. An expired ID will not work at security, even if you have a renewal process in progress. If your ID expires before your trip, renew it as soon as possible — processing times vary by state but often take 2 to 4 weeks.

What if my name on my ticket doesn't match my ID exactly?

Contact your airline before you go to the airport. Small differences like "Robert" versus "Bob" or a missing middle initial can sometimes be corrected in the booking system. If you can't fix it before your flight, bring documentation showing both names — a marriage certificate, divorce decree, or court order — and explain the situation to the airline agent at check-in.

Do I need to show my ID at the gate, or just at security?

You need to show your ID at security. At the gate, the airline scans your boarding pass but may ask for ID again if there's a name mismatch or other issue. Keep your ID accessible throughout the airport.

Can I fly with a military ID or employee badge?

A military ID works as a valid photo ID for domestic flights. Most employee badges do not, unless they're issued by a federal agency and meet Real ID standards. If you're unsure, bring a driver's license or passport as backup.

What if I'm flying the day after my ID expires?

An expired ID will not work, even by one day. You'll need to use the identity verification process at security, which takes longer. Plan to arrive at least 3 hours before your flight if this is your situation.
