REAL ID vs Passport: Which Works for Domestic Flights in 2026?

TL;DR

Both a REAL ID-compliant driver’s license and a U.S. passport work at every TSA checkpoint for domestic flights in 2026. The REAL ID is cheaper ($25–$50 at your DMV) but only covers domestic travel. The passport costs more ($165+ for a new book) but covers domestic and international flights. If you fly internationally even occasionally, get the passport — it solves both problems with one document.

Why this comparison matters

Since TSA began full REAL ID enforcement on May 7, 2025, travelers who show up with a non-compliant driver’s license face lengthy secondary screening — or, in the worst case, miss their flight. That enforcement has made a lot of people ask: “Should I upgrade my license, or just use my passport?”

Both are valid answers. The right one depends on how you travel. This article breaks it down without fluff.

What REAL ID actually covers

A REAL ID-compliant driver’s license (the one with the gold or black star in the upper-right corner) was designed by the federal government to set a minimum identity-verification standard for state-issued IDs. Under the REAL ID Act, it covers:

• Domestic commercial flights — all TSA checkpoints
• Federal government buildings that require ID to enter
• Nuclear power plants and certain military bases

That’s where it stops. A REAL ID does not let you board an international flight, cross a land border into Canada or Mexico, or serve as a travel document abroad. It is a domestic-only document.

If you want to upgrade your license to REAL ID, you’ll visit your state DMV in person with a certified birth certificate (or passport), proof of Social Security number, and two proofs of address. Most states charge $25–$50 for the upgrade. The catch: DMV appointments in many states book out 4–8 weeks ahead.

What a U.S. passport covers

A U.S. passport book is the broadest travel document available to American citizens. It covers:

• All domestic flights — accepted at every TSA checkpoint
• All international flights — required for air travel outside the U.S.
• Land and sea border crossings with Canada and Mexico
• Entry to most countries worldwide (188+ countries visa-free or visa-on-arrival)

An adult passport book costs roughly $165 in government fees alone: $130 application fee plus a $35 acceptance facility fee. Add a passport photo ($10–$20) and any service or expediting fees on top of that. It’s more expensive upfront but valid for 10 years — which works out to about $16.50/year.

A passport card is a wallet-sized alternative ($65 new) that works for domestic flights and land/sea border crossings, but not international air travel. If you want to keep something small in your wallet alongside your driver’s license, the card is worth knowing about. We compare the two in Passport Card vs Passport Book.

The honest cost comparison

REAL ID route: $25–$50 at the DMV, plus the time cost of an in-person appointment. If your license is expiring soon anyway, the REAL ID upgrade is often free or bundled into your renewal fee.

Passport route: $165+ in government fees for a new book, plus several weeks of processing time (4–6 weeks routine; faster if you pay the $60 expedite fee). If you’re renewing an existing passport by mail via DS-82, the acceptance facility fee drops off and the process is simpler.

What the math actually looks like: If you fly domestically twice a year and never leave the country, a REAL ID is the practical choice. If you’ve traveled internationally even once in the last five years, a passport pays for itself in convenience.

Which documents are accepted at TSA — the full list

TSA’s official accepted ID list includes the following (not a complete list — see TSA.gov for the full current version):

Document	Domestic flights	International flights
REAL ID-compliant driver’s license	Yes	No
U.S. passport book	Yes	Yes
U.S. passport card	Yes	No (air)
Enhanced Driver’s License (EDL)	Yes	Land/sea only
Global Entry card	Yes	Yes (entry)
Permanent resident card	Yes	Entry only
U.S. military ID	Yes	—
TSA PreCheck KTN alone	No (ID still required)	No

Note on PreCheck: having a Known Traveler Number speeds you through the PreCheck lane, but it does not replace your ID requirement at the checkpoint. You still need one of the documents above.

Common pitfalls

• Assuming REAL ID works for international flights. It doesn’t. A REAL ID-compliant driver’s license is rejected at international departure gates. Pack your passport book.
• Confusing the passport card with the passport book. The card works for domestic flights and land/sea crossings. It does not work for international air travel — not even to Canada or Mexico by plane.
• Waiting on the DMV. REAL ID appointments in major states book 4–8 weeks out. Don’t plan on upgrading the week before your flight.
• Letting your passport expire and assuming your license covers everything. If your license isn’t REAL ID-compliant and your passport is expired, you have no accepted federal ID. Sort this before your next trip.
• Thinking a star on your license means it’s valid. Stars only matter if the license itself is current. An expired REAL ID-compliant license is still an expired ID.

What to do next

If you never travel internationally and already have a REAL ID: you’re covered for domestic flights. No action needed.

If you don’t have a REAL ID yet and need to fly domestically soon: the fastest fix is a valid U.S. passport if you have one. Otherwise, book your DMV appointment now — don’t wait until the week before travel.

If you travel internationally even occasionally: a passport is the better long-term document. It covers domestic flights, international flights, and border crossings. One document, no trade-offs.

Frequently asked questions

Can I use a REAL ID for domestic flights in 2026?

Yes. A REAL ID-compliant driver’s license is accepted at every TSA checkpoint for domestic travel. Look for the star in the upper-right corner of your license to confirm it’s compliant.

Does a REAL ID work for international flights?

No. REAL ID is accepted only for domestic flights and entry into federal buildings. For any international flight you need a valid U.S. passport book — a REAL ID alone will not work.

Which is cheaper — getting a REAL ID or a passport?

REAL ID is cheaper upfront. Most states charge $25–$50 to upgrade your driver’s license. A new passport book costs $165 in government fees alone ($130 application fee + $35 acceptance fee), plus any photo and service fees.

How long is a REAL ID valid?

A REAL ID is tied to your driver’s license, so it expires on the same schedule — typically 4–8 years depending on your state. An adult U.S. passport book is valid for 10 years.

What if I fly internationally just once or twice a year?

Get the passport. Even occasional international travel makes a passport worth the cost. It covers every domestic flight too, so you can carry one document instead of two.

Is a passport card the same as a passport book for domestic flights?

Yes — a U.S. passport card is accepted at TSA checkpoints for domestic flights, just like the passport book. The card costs less ($65 new) but cannot be used for international air travel.
