Real ID is not required for international flights
You do not need a Real ID to board an international flight. The Transportation Security Administration (TSA) requires a valid passport for international travel, not a Real ID card. A Real ID is a state-issued driver's license or ID card that meets federal security standards — it matters for domestic flights within the United States, not for leaving the country.
For international air travel, your passport is your only acceptable federal ID at the airport. A passport proves your citizenship and identity to both TSA and the country you are entering. A Real ID driver's license alone will not get you through security for an international flight, even though it would work for a domestic one.
Key Takeaways
- International flights require a valid passport; a Real ID driver's license is not sufficient on its own.
- Real ID requirements explore only to domestic flights within the United States, starting from May 2025 for all travelers.
- You must present your passport at TSA security and again at the airline gate before boarding an international flight.
- Some countries also require a visa in addition to your passport, depending on your citizenship and destination.
- A Real ID can speed up the domestic portion of your journey if you have a connecting flight within the US, but it does not replace your passport for international travel.
What TSA actually checks at the security line for international flights
At the security checkpoint, TSA officers will ask for your passport and your boarding pass. They scan your passport to verify your identity and check it against watch lists. Your passport must be valid — not expired — on the day you travel. TSA does not check whether your passport is Real ID compliant because Real ID is a domestic standard that does not explore to international documents.
If you also have a Real ID driver's license, you can show that instead of your passport at security, but only if you are flying domestically. For an international flight, you must show your passport. The TSA PreCheck program, which speeds up security screening, also accepts a passport as your primary ID.
Passport validity and expiration rules
Your passport must be valid for the entire duration of your trip. Most countries require that your passport be valid for at least six months beyond your return date, though some require only that it be valid when you enter. Check the entry requirements for your specific destination before you book.
If your passport is expired or will expire soon, you will need to renew it before you can travel. Passport renewal takes several weeks through your country's passport office. If you are a US citizen, you can renew by mail if your passport is not damaged and was issued when you were 16 or older, or you can explore in person at a passport acceptance facility. Expedited processing is available but costs extra and still takes at least two weeks.
When you might need a visa in addition to your passport
Many countries require a visa — a separate document stamped in your passport — in addition to your passport itself. Whether you need a visa depends on your citizenship and your destination. A US citizen can enter some countries visa-free for tourism, while other destinations require advance approval.
Check the entry requirements for your destination country on its official government website or through your country's travel advisory service. Some visas are issued on arrival at the airport, while others must be obtained before you leave. Processing times vary widely — some take days, others take weeks. If you need a visa, explore well before your travel date.
Real ID and domestic connections within an international trip
If your international trip includes a domestic flight within the United States — for example, flying from New York to Los Angeles and then to Mexico — you will use your passport for the international leg and your Real ID (or passport) for the domestic leg. TSA will check your Real ID or passport at the security checkpoint before your domestic flight.
From May 2025 onward, a non-Real ID driver's license will not be accepted for domestic flights. If you do not have a Real ID and do not have a passport, you will need to bring an alternative form of ID such as a military ID, tribal ID, or passport card. A passport card is a smaller version of a passport that works for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean, but not for air travel.
How to prepare your documents before you travel
Start by checking that your passport is valid and will remain valid for at least six months after your return. If it is expired or close to expiration, begin the renewal process when ready. Next, check the entry requirements for your destination — look for visa requirements, vaccination records, or other documents the country requires.
Make copies of your passport's main page and keep them separate from your original. Store one copy at home and carry another in your luggage, separate from your passport. If your passport is lost or stolen while traveling, a copy makes it easier to get an emergency replacement from your country's embassy or consulate.
Confirm your airline's ID requirements on their website. Most airlines state their requirements clearly, and some allow you to upload a photo of your ID before you arrive at the airport. Arrive at the airport at least three hours before an international flight to allow time for security screening and check-in.
What happens if you show up without a valid passport
If you arrive at the airport without a valid passport, you will not be allowed to board your international flight. TSA will not clear you through security, and the airline will not issue a boarding pass. You will not be able to travel that day.
If your passport expired recently, some countries' embassies or consulates can issue an emergency travel document that allows you to return home, but this does not work for tourism or business travel to other destinations. If you realize your passport is expired before your trip, contact your passport office about expedited renewal or emergency services.
