What Documents Do I Need at the US Airport

The answer depends on where you’re going. A domestic flight within the United States usually centers on identification at the TSA checkpoint. An international trip also involves passports, visas, and documents for entering another country or returning to the United States.

A simple family airport folder can keep this clear. Make one section for domestic travel, one for international travel, and one for U.S. entry documents. Then check each traveler’s documents before you leave home.

Documents commonly needed for a domestic flight in the United States

For a flight within the USA, you’ll usually need government-issued identification for the traveler going through the TSA checkpoint. The identification must match the current requirements in place when you travel.

Examples listed for airport identification include:

• A state-issued REAL ID-compliant driver’s license
• A state-issued REAL ID-compliant identification card
• A state-issued Enhanced Driver’s License
• A state-issued Enhanced Identification Card
• A valid passport
• A green card
• A military ID
• Other accepted government-issued identification

This is the basic answer to “what documents do I need at the US airport?” for a domestic trip: bring an accepted form of ID, and keep your reservation details available through your airline’s app, email, or booking record.

Your airline may also ask for information before boarding. For example, it may need the passenger’s name and booking details. The airline’s rules can differ from the TSA checkpoint rules, so check both.

A birth certificate may be useful when traveling with a child, especially if the airline asks for proof of age or identity. However, the available guidance does not support treating one child-document list as a rule for every trip. Children’s document needs can vary by airline, destination, age, and travel situation.

For that reason, don’t assume that the documents you use for yourself are enough for a baby or toddler.

Identification accepted at the TSA checkpoint

The TSA checkpoint is where your identity documents are reviewed before you enter the secure part of the airport. This is separate from the airline counter and separate from immigration inspection on an international trip.

For adults, prepare one current form of identification from the types accepted by TSA. The research examples include:

• REAL ID-compliant state licenses and ID cards
• Enhanced state-issued driver’s licenses and identification cards
• Passports
• Green cards
• Military IDs
• Other government-issued IDs listed by TSA

Keep the physical document easy to reach. A photo of your license on your phone may not work as a replacement for the actual identification document. Your airline app can help with your booking, but it does not replace the ID required at the checkpoint.

If your name has changed, think ahead about possible mismatches between your identification and booking. If the names on your documents and reservation don’t line up, ask the airline what it needs before travel. Don’t wait until you’re standing in the airport line with a tired child.

The same rule applies if a document is expired, damaged, lost, or difficult to read. Check the current TSA guidance instead of assuming the document will be accepted.

REAL ID, regular driver's licenses, and flying in 2026

REAL ID is a type of state-issued driver’s license or identification card that meets federal security standards. A REAL ID is usually marked in a way that identifies it as compliant.

Travelers are asking a very specific question: Can I fly without a REAL ID in 2026?

The information available here does not establish the full 2026 rule or confirm every alternative in every situation. It does show that TSA identification examples include passports, green cards, military IDs, enhanced state licenses, enhanced state ID cards, and REAL ID-compliant licenses and cards.

So don’t treat REAL ID as the only possible document. If you don’t have one, check the current TSA requirements and see whether you already have another accepted form of identification.

A regular driver’s license needs a closer look. The available guidance specifically highlights REAL ID-compliant state licenses and enhanced identification. It does not confirm that every ordinary state driver’s license will be accepted for every airport trip.

Before relying on a regular license, confirm its current status with TSA. If you have a passport, green card, military ID, or another listed form of ID, check whether it can serve as your airport identification instead.

For a family folder, make a note beside each adult’s name:

• REAL ID-compliant license or ID card
• Enhanced license or ID card
• Passport
• Green card
• Military ID
• Another government-issued ID
• Needs verification

That small note can prevent a last-minute scramble.

When you need a passport for international travel

You need a passport for international travel. This applies when you’re flying from the United States to another country, even if the flight is short or you’re traveling to visit family.

A passport is different from the ID you might use for a domestic flight. Your driver’s license may help with the TSA checkpoint, but it is not a substitute for a passport when crossing an international border.

International trips may also require a visa or another travel authorization. The exact documents depend on the country you’re visiting and the traveler’s citizenship or immigration status. The airline may review these documents before you board because it must follow the destination’s entry rules.

For each traveler, check:

• Passport
• Visa, if required
• Any destination-specific entry document
• Airline instructions for international check-in
• Passport and document validity requirements
• Documents needed for children traveling with you

Put the passports together in one protected section of your family folder. Keep them close during the journey. Don’t pack them in checked luggage.

If you’re traveling with a baby or toddler, check the child’s passport separately. A child’s documents should not be treated as covered simply because the child is listed on a parent’s reservation.

Documents for entering the United States from abroad

Flying to the United States from another country adds another document check. On arrival, travelers are reviewed by U.S. immigration authorities.

U.S. arrival guidance lists these documents among those travelers may need:

• A valid passport
• A valid U.S. visa

The correct documents can vary by traveler and situation. A U.S. citizen, a permanent resident, and a visitor may not have the same entry documents.

A green card is an important document for a lawful permanent resident returning to the United States. Keep it available with the traveler’s passport and other travel papers. Don’t put it in checked baggage.

If you’re entering the United States after an international trip, separate these papers from your domestic TSA identification. You may show identification at the airport, but immigration officers may need different documents for entry.

For a return trip, your folder might include:

• Passport
• U.S. visa, if applicable
• Green card, if applicable
• Other immigration documents requested for your situation
• Airline booking details
• Child travel documents

Check official U.S. immigration guidance and your airline before departure. A document that gets you through the TSA checkpoint may not be enough to enter the United States.

Extra document checks for green card holders, military travelers, and government business

Some travelers already carry documents that can help with airport identification, but the reason for the trip still matters.

Green card holders

A green card is listed among identification examples for airport travel. It may also matter when a permanent resident returns to the United States from abroad.

Carry the physical green card with your passport when traveling internationally. Check the current entry guidance for your situation before leaving. A green card is not a universal replacement for every travel document or visa requirement.

Military travelers

A military ID is also listed as an airport identification example. Make sure the traveler has the correct physical ID available at the checkpoint.

If the trip involves official orders or military business, keep any required travel paperwork with the military ID. The available research does not provide a complete list of military travel documents, so confirm the details through the appropriate official channel.

Government business

Traveling for government work may involve a government-issued ID or other business-related papers. The exact requirements can depend on the trip and the traveler’s role.

Keep official work documents separate from ordinary boarding information. Ask your agency or employer what must be carried, and still confirm the TSA requirements for the flight.

What parents should organize before flying with a baby or toddler

Family travel gets easier when each person has a clear document place. You don’t want to search through three bags while holding a crying baby.

Make a child section in your airport folder for each baby or toddler. Add:

• The child’s passport for international travel
• Any visa or destination document required for the child
• A birth certificate or other proof of age if the airline tells you to bring one
• The child’s ticket or booking information
• Any custody, consent, or other family-travel papers that apply to your situation
• Copies or backup records stored safely, if useful for your trip

The exact rules for children can change based on the airline, destination, age, and who is traveling with the child. A child flying with one parent may raise different questions from a child flying with both parents. The research provided here does not establish one universal consent-letter or birth-certificate rule, so don’t rely on a general internet checklist.

Ask the airline what it wants before the travel day. For international trips, check the destination country’s entry rules for children. Also confirm the requirements with the relevant U.S. authority when returning to the country.

Keep the child’s documents with you, not in a stroller bag or checked suitcase. If a document is needed at the counter or checkpoint, you’ll want it within easy reach.

Airport document checklist before leaving home

Use this checklist the night before your flight. It’s short enough to keep on your phone, but a printed copy can help when you’re managing luggage and children.

For every trip

• Check the airline booking for every traveler.
• Confirm the name on each booking.
• Choose the correct government-issued ID for each adult.
• Check that passports, green cards, and other important documents are physically with you.
• Put documents in one easy-to-reach folder.
• Keep travel documents out of checked bags.

For a domestic flight

• Bring accepted government-issued identification.
• Check whether your state license is REAL ID-compliant.
• If using a regular driver’s license, verify that TSA will accept it for your trip.
• Consider another listed ID, such as a passport, green card, or military ID.
• Confirm any child document request with the airline.

For an international flight

• Bring a valid passport for every traveler.
• Check whether a visa or other destination document is needed.
• Review airline instructions for international check-in.
• Check the requirements for babies and toddlers.
• Keep passports and visas together in your carry-on.

For entering the United States

• Carry a valid passport.
• Carry a valid U.S. visa when required.
• Bring a green card if the traveler is a permanent resident.
• Check the current immigration guidance for the traveler’s status.
• Keep children’s documents separate and easy to show.

Use the checklist to build your family airport folder, then verify the exact documents with TSA, your airline, and the relevant destination or U.S. immigration authority before leaving. That last check matters most for REAL ID questions, regular driver’s licenses, international trips, and travel with young children.
