What is domestic travel?
Domestic travel is any trip that stays within US states, territories, or possessions. No passport is required. For domestic flights, you need a REAL ID-compliant driver’s license or another accepted ID. Non-compliant travelers can pay a $45 TSA ConfirmID fee since February 2026, but should expect up to 30 minutes of extra processing.
Domestic travel means any travel that takes place entirely within the United States, including its states, territories, and overseas possessions. No passport is required, and unlike international travel, there are no customs or immigration checkpoints to clear. The main documentation you need is a valid, government-accepted form of ID.
What Is Domestic Travel?

The word “domestic” comes from the Latin domus, meaning home. In travel, it refers to any trip where both the origin and destination fall within the same country. For US citizens, domestic travel covers all 50 states plus a set of territories and overseas possessions that fall under US jurisdiction, none of which require a passport to enter.
Destinations that count as domestic travel for US citizens include all 50 US states plus the following territories and associated entities:
- American Samoa
- Guam
- Marshall Islands
- Micronesia
- Midway Islands
- Northern Mariana Islands
- Palau
- Puerto Rico
- U.S. Virgin Islands
- Wake Island
- And several other minor US outlying islands
Traveling to or between any of these destinations is considered domestic, not international. That matters mostly for two reasons: no passport is required, and you won’t go through customs or immigration on arrival.
One Exception: Driving to Alaska
Driving from the continental United States to Alaska requires passing through Canada, which is an international border crossing even though your destination is a US state. You’ll need a passport or passport card for that crossing. Flying from the continental US to Alaska, however, is domestic travel with no border crossing involved.
Domestic vs. International Travel

The core distinction is simple: domestic travel begins and ends within the same country’s jurisdiction. International travel crosses into another country’s territory at some point during the trip. Here’s how that plays out in practice:
- A flight from New York to Miami: domestic
- A flight from New York to Paris: international
- A flight from California to Guam: domestic (Guam is a US territory)
- A flight from California to Japan: international
- A drive from Washington state to Alaska through Canada: technically crosses an international border, but the destination is domestic
Travel between the US and Canada or Mexico is sometimes called trans-border travel, which is a subset of international travel. Despite how common it is, it still requires a passport or passport card, and travelers clear customs on both entry and return.
ID Requirements for Domestic Air Travel in 2026

REAL ID enforcement began on May 7, 2025. As of that date, non-compliant state driver’s licenses are no longer accepted at TSA checkpoints for domestic flights. If you’re flying domestically in 2026, you need one of the following:
- A REAL ID-compliant driver’s license or state ID (look for a star symbol in the upper right corner)
- A US passport or passport card
- A US Department of Defense ID
- Trusted traveler cards issued by DHS (NEXUS, SENTRI, FAST, Global Entry)
- A permanent resident card
- A border crossing card
- A photo ID issued by a federally-recognized Tribal Nation
- A foreign government-issued passport
- A Transportation worker identification credential (TWIC)
- A US Merchant Mariner Credential
- A Veteran Health Identification Card
Children under 18 are not required to present ID when traveling domestically. The full current list of accepted IDs is maintained by the TSA on its official identification page.
What Happens if You Don’t Have a REAL ID?
Since February 1, 2026, travelers who arrive at airport security without a compliant ID can pay a $45 fee to use TSA ConfirmID, an identity verification system that uses biometric and biographical data to establish identity. The $45 covers a 10-day travel window, meaning it is valid for round-trip flights taken within that period. It is non-refundable, and travelers using ConfirmID should expect up to 30 minutes of additional processing time at the checkpoint. TSA strongly recommends paying the fee online before arriving at the airport if you know you’ll need it.
Arriving without compliant ID and without pre-paying the fee is not a viable plan. You may be turned away from the checkpoint entirely.
Expired IDs
TSA currently accepts expired IDs that have been expired for less than two years, for the forms of identification on the accepted list. An expired driver’s license that expired three years ago is not accepted.
What Is Not Accepted
Temporary driver’s licenses, paper IDs issued while awaiting a permanent card, and weapons permits are not accepted at TSA checkpoints for domestic flights. A driver’s license without the REAL ID star is also no longer accepted unless you pair it with another item on the accepted list, such as a passport.
Frequently Asked Questions

What is the meaning of domestic travel?
Domestic travel means traveling entirely within the borders, states, territories, or possessions of your home country. For US citizens, this includes all 50 states plus territories like Puerto Rico, Guam, and the US Virgin Islands. No passport is required for domestic travel, and you do not go through customs or immigration.
What is an example of domestic travel?
Flying from New York to Los Angeles, driving from Texas to Florida, or flying from California to Puerto Rico are all examples of domestic travel. Even traveling within a single state, like from Chicago to Springfield, is domestic travel. The common factor is that the journey never crosses into a foreign country’s territory.
What is considered US domestic travel?
Any trip where your starting point and destination are both within US jurisdiction, including states and territories, is domestic travel. If you will not cross into a foreign country at any point during the journey, it qualifies as domestic. No passport is required, though a REAL ID-compliant driver’s license or other accepted ID is needed for domestic flights.
What is the difference between domestic and international travel?
Domestic travel stays within your home country’s jurisdiction throughout the entire trip. International travel involves entering a foreign country’s territory. A flight from the US to Canada is international travel, even though Canada is a close neighbor. A flight from the US to Guam is domestic travel, even though Guam is far from the continental US.
Is Hawaii considered a domestic flight?
Yes. Hawaii is a US state, so flying there from anywhere else in the United States is a domestic flight. No passport is required. A REAL ID-compliant driver’s license or other accepted ID is sufficient for airport security.
Do I need a REAL ID for domestic flights in 2026?
Yes. REAL ID enforcement began on May 7, 2025, and non-compliant state IDs are no longer accepted at TSA checkpoints for domestic flights. You need either a REAL ID-compliant driver’s license (look for the star in the upper right corner) or another accepted form of ID such as a US passport. Travelers who show up without compliant ID can pay a $45 TSA ConfirmID fee to undergo alternative identity verification, but this adds up to 30 minutes of processing time and is non-refundable.
