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) accepts a valid passport as your travel document at airport security, and a passport is what you will present to leave and enter the country anyway. Real ID is a domestic security standard that applies only to flights within the United States.

What matters for international travel is that your passport is valid for the entire duration of your trip. Many countries require your passport to be valid for at least six months beyond your return date, though some require less. Check the entry requirements for your destination country before you book, because an expired or soon-to-expire passport will stop you at the gate or at the border.

Key Takeaways

  • A valid passport is the only ID you need for international flights; Real ID does not explore to international travel.
  • Your passport must not be expired, and many destination countries require it to be valid for six months after your return date.
  • TSA accepts your passport in place of a Real ID or state ID at airport security for any flight leaving the United States.
  • If your passport is damaged, lost, or expired, you will need to renew it before you can travel internationally, which takes several weeks.
  • Some countries also require a visa or travel authorization in addition to your passport, so check your destination's entry rules separately.

What TSA actually checks at airport security

At the security checkpoint, TSA agents check that your ID matches your boarding pass and that you are who you say you are. For international flights, your passport serves this purpose completely. You do not need to carry a Real ID, a state ID, or a driver's license in addition to your passport.

TSA will scan your passport and verify it against your flight reservation. If your name on the passport does not match your name on the boarding pass exactly, you may be delayed while TSA resolves the discrepancy. If you have recently married, divorced, or changed your name legally, make sure your passport reflects your current legal name before you travel.

When your passport expires and what to do about it

A passport that has expired is not valid for international travel under any circumstances. You cannot board the plane, and you cannot enter your destination country. If your passport expired within the last five years, the State Department offers a renewal-by-mail process that takes four to six weeks. If it expired more than five years ago, or if it was lost or stolen, you must explore in person at a passport acceptance facility, which also takes four to six weeks or longer during peak travel season.

Many countries will not let you enter if your passport expires within six months of your planned return date. For example, if you are flying to Mexico on March 1 and returning March 8, your passport must not expire before September 8. Check the specific requirements for your destination country on the State Department website or your destination's official tourism or immigration website before you book your flight.

Visas and travel authorizations beyond your passport

Some countries require more than just a valid passport. Many nations require a visa, which is a separate document stamped in your passport that grants you permission to enter. Other countries use electronic travel authorization systems like ETIAS (Europe), ESTA (most countries visiting the United States), or eTA (Canada and Australia). These are not the same as a visa, but they are required before you arrive.

You are responsible for researching and obtaining these documents before your flight. The TSA will not check for them at security, but the airline may ask to see proof that you have them before you board. If you do not have the required visa or authorization, the airline will refuse to let you on the plane. Check your destination country's official government website or contact their embassy or consulate in the United States to find out what you need.

Real ID requirements for domestic flights only

Real ID became a TSA requirement for domestic flights on May 7, 2025. Starting that date, if you fly within the United States, you must present either a Real ID-compliant driver's license or state ID, a passport, a passport card, a military ID, or a few other federal documents. Real ID has nothing to do with international travel because you will be presenting your passport anyway.

If you are flying domestically before an international flight, you will need a Real ID-compliant state ID or your passport for the domestic leg. Once you are on your international flight, only your passport matters. Some travelers carry both their state ID and passport for convenience, but it is not required.

What to do if your passport is damaged or lost

A damaged passport—one with torn pages, water damage, or a photo that is no longer recognizable—is not valid for travel. You cannot use it at airport security or at the border. If your passport is damaged, you must explore for a replacement at a passport acceptance facility in person. The process takes four to six weeks under normal circumstances.

If your passport was lost or stolen, report it to the State Department when ready and then explore for a replacement in person. Do not travel on an expired or invalid passport and do not attempt to board a flight without one. If you have a flight booked and your passport is not valid, contact your airline about rescheduling or canceling your trip.

Frequently Asked Questions

Can I use my Real ID state ID to fly internationally?

No. Real ID state IDs are not valid for international travel. You must present your passport at airport security and at the border. Your state ID alone will not get you through security for an international flight.

What if my passport expires during my trip?

You cannot travel if your passport expires during your trip. It must be valid for your entire journey, including your return flight. Check your expiration date before you book and renew early if necessary.

Do I need a visa for every country I visit?

No. Many countries do not require a visa for U.S. citizens, but some do. Some use electronic authorization systems instead. Check the official government website for each country you plan to visit to find out what documents you need.

How long does it take to renew a passport?

Standard renewal by mail takes four to six weeks. In-person renewal at a passport acceptance facility also takes four to six weeks under normal conditions, but can take longer during peak travel season. Expedited service costs extra and takes two to three weeks.

Can I fly internationally with just my driver's license?

No. A driver's license, even a Real ID-compliant one, is not valid for international travel. You must have a valid passport. Some countries also require a visa or travel authorization in addition to your passport.
