Do you need a passport to travel in the US?

If you are flying to the United States for the major summer soccer tournament, you may be wondering: do you need a passport to travel in the US? 

For domestic flights inside the country, adult travelers do not necessarily need a passport, but they do need a REAL ID-compliant state ID or another TSA-accepted document. If you are arriving from Mexico with Volaris and then connecting between US host cities, understanding ID rules can help you move through airport security with fewer delays.

Travelers planning match trips to destinations such as Atlanta, Boston, Miami, New York, Los Angeles, Houston, Dallas, San Francisco, and Seattle should confirm their identification before booking routes. Once you enter the US from another country, domestic travel rules apply to any internal flight you take.

What is REAL ID and why does it matter?

REAL ID is a federal identification standard for state-issued driver’s licenses and ID cards. Full enforcement for domestic air travel began on May 7, 2025, which means adults need a REAL ID-compliant license or another acceptable identification document to board domestic flights.

A REAL ID-compliant card usually has a star marking in the upper right corner. If your license or state ID does not have this marking, it may not be accepted at TSA checkpoints for domestic air travel.

This matters for fans taking national flights between US cities during the tournament. A short connection between host cities can still require the correct airport ID, even if the flight never leaves the United States.

Acceptable ID for domestic flights beyond passports

A passport for domestic flights is accepted, but it is not the only option. Adult passengers can use several TSA-accepted documents for domestic air travel.

Common accepted IDs include:

• REAL ID-compliant driver’s license or state ID.

• US passport book.

• US passport card.

• DHS trusted traveler card, such as Global Entry, NEXUS, SENTRI, or FAST.

• State-issued Enhanced Driver’s License.

• Permanent resident card.

• US Department of Defense ID.

• Federally approved mobile driver’s license, where accepted.

If you are researching the ID needed to fly domestic, check the TSA list before your trip because accepted document rules can change. International travelers should also remember that a passport is still required to enter the US from abroad, even if a passport is not always required for a domestic flight within the country.

What happens if you don't have an acceptable ID?

If you arrive at a TSA checkpoint without acceptable identification, you may face additional identity verification. TSA’s ConfirmID process may be available, but it can add time, involve a fee, and does not guarantee approval.

This backup option is not a good travel strategy for tight itineraries. Fans heading to a match should avoid relying on last-minute verification because delays could affect connections, hotel check-in, or kickoff plans.

Before the airport, confirm what ID for US flights applies to your situation. If you are not sure whether your license is REAL ID-compliant, bring another accepted document, such as a passport book or passport card.

How to get a REAL ID before your next trip

The process for getting a REAL ID depends on your state. In most cases, travelers must visit their state driver licensing agency and provide proof of identity, Social Security number, and residency.

Before applying, check whether your current license already has the star marking. If it does, you likely meet Real ID requirements for domestic flights.

To prepare for a REAL ID appointment, you may need:

• Proof of identity, such as a passport or birth certificate.

• Proof of Social Security number.

• Proof of state residency.

• Legal name change documents, if applicable.

• Current driver’s license or state ID.

Start early if your match trip includes multiple US cities. Appointment availability and processing times can vary, especially during peak travel seasons.

ID requirements for children and minors

TSA does not require children under 18 to show ID when traveling with an adult on domestic US flights. The adult companion must present acceptable identification, and the airline may rely on the adult’s information for the minor.

However, airlines can request proof of age or additional documents in certain situations, such as lap infants, unaccompanied minors, or special fare rules. For this reason, families should carry a copy of a birth certificate or other age-related document when traveling with children.

If a child is traveling internationally to reach the US, passport rules still apply. The minor exception is for TSA domestic screening, not for entering the country from abroad.

Planning your domestic travel with confidence

Understanding domestic travel documents in USA airports can prevent unnecessary stress. If you are flying within the country after arriving internationally, keep your passport accessible even when taking a domestic connection.

Travelers coming from Mexico for soccer flights should plan both parts of the journey: entry documents for the US and TSA-accepted ID for any domestic route. A passport book covers both international entry and domestic airport identification, making it the simplest option for many visitors.

Practical airport tips include arriving early, checking your airline app, saving boarding passes offline, keeping your ID in an easy-access pocket, and making sure the name on your booking matches your identification.

Frequently asked questions
