TSA and REAL ID Rules for Families in 2026: What Parents Need to Know

If your family last flew a couple of years ago, the airport security line has changed more than you might expect. REAL ID is now enforced. Since February 2026 there's a fee if an adult turns up without acceptable ID. And the shoes-off routine is gone.

Here's what that means for parents flying in the U.S. this fall and winter, checked against TSA and DHS pages as of October 2026. The TSA says its ID list can change without notice, so recheck the links the week you fly.

The short version

Do kids need ID to fly?

For domestic flights, the TSA's answer is simple: TSA does not require children under 18 to provide identification when traveling within the United States. That covers toddlers and 15-year-olds alike.

There are two catches:

• Airlines can have their own rules. The TSA itself tells families to check with the airline about ID for travellers under 18. If you're flying with a lap infant, the airline may ask for proof that your baby is under two. Southwest, for instance, accepts only government-issued documents such as a birth certificate or passport, and says it won't accept screenshots or photos. A photocopy of the birth certificate in the diaper bag is cheap insurance.
• Teens flying alone with PreCheck. The TSA says unaccompanied minors who are eligible for PreCheck must show acceptable ID to get expedited screening.

Watch for one easy-to-miss milestone: the ID requirement applies to adult passengers 18 and older. If your teen has an 18th birthday before the trip, they now need their own REAL ID, passport or other acceptable ID, just like you.

REAL ID: the rule every adult now needs to meet

REAL ID enforcement began May 7, 2025. Since then, the TSA no longer accepts state-issued driver's licenses and ID cards that aren't REAL ID compliant at airport checkpoints. A REAL ID card is marked with a star in the upper corner. An Enhanced Driver's License also works.

If your license doesn't have the star, you can still fly with another document from TSA's acceptable ID list, including:

• A U.S. passport or passport card
• A DHS trusted traveler card (Global Entry, NEXUS, SENTRI, FAST)
• A U.S. Department of Defense ID, including IDs issued to dependents
• A photo ID from a federally recognized Tribal Nation, including Enhanced Tribal Cards
• A state mobile driver's license (mDL) from an approved state, as long as it's based on a REAL ID, EDL or EID

A few details trip people up. The TSA says a temporary driver's license is not acceptable. It does accept expired IDs from the list for up to two years after they expire. And if you plan to use a digital ID on your phone, the TSA's ConfirmID FAQ says you must still bring your physical ID to the checkpoint.

If one parent hasn't upgraded their license yet, a valid passport solves the problem for domestic flights too.

No REAL ID? Meet TSA ConfirmID and its $45 fee

This is the big change for 2026. Since February 1, 2026, an adult who can't show an acceptable ID at the checkpoint can pay a $45 fee to use TSA ConfirmID. The TSA then tries to verify that person's identity some other way. Here's how it works, according to the TSA:

• You pay online through Pay.gov, by bank account, debit or credit card, Venmo or PayPal. Cash isn't accepted, at the airport or anywhere else.
• Each adult 18 or older without acceptable ID has to go through ConfirmID separately. Someone else can pay on their behalf, but the traveller's name and travel date must be entered correctly.
• One payment covers 10 days of travel, starting from the travel date on the receipt. So a short round trip may be covered by a single payment.
• Keep the receipt. You'll show the Pay.gov confirmation email (printed or on your phone) at the checkpoint. If you can't produce it, you may have to pay again.
• Verification takes time and isn't guaranteed. The TSA says the process averages 10 to 15 minutes but can take 30 minutes or more. There's no promise it will succeed.
• Pay before you get in line. If you reach the checkpoint without acceptable ID and haven't paid, the TSA says you'll have to leave the line, pay, and go to the back.

With a tired toddler in tow, losing your place in a holiday security line is the last thing you need. If anyone is missing an acceptable ID, sort it out (or prepay ConfirmID) days ahead.

The 3-1-1 liquids rule, and the big exemption for parents

The liquids rule is still in force in 2026. The TSA's liquids, aerosols and gels rule lets you carry a quart-sized bag of travel-size containers of 3.4 ounces (100 milliliters) or less per item. Anything bigger goes in checked baggage.

The rule bends for children's food and drink. Under the TSA's traveling with children guidance:

• Formula, breast milk, toddler drinks and baby or toddler food, including puree pouches, are allowed in your carry-on in amounts over 3.4 oz.
• They're treated as medically necessary liquids, so they don't have to fit in the quart-size bag.
• Ice packs, freezer packs, gel packs and liquid-filled teethers are allowed, whether or not breast milk is with you.
• Your child doesn't need to be travelling with you for you to bring breast milk and cooling accessories.
• Tell the officer at the start of screening and take these items out of your bag to be screened separately.

The same idea covers medicine. The TSA allows larger amounts of medically necessary liquids "in reasonable quantities for your flight," as long as you declare them at the checkpoint. That includes things like a child's liquid prescription. The TSA says screening will never involve putting anything into the liquid, and you can ask that it not be X-rayed (expect extra screening if you do).

Shoes on: the 2025 change

On July 8, 2025, DHS announced the end of the "shoes-off" policy, letting passengers at domestic airports keep their shoes on through security screening. Other layers of screening, such as identity verification, still apply.

For parents, this mostly changes things for the adults: TSA guidance already lets children 12 and under keep their shoes, light jackets and headwear on. Slip-on shoes are no longer a must, but check tsa.gov before you go.

TSA PreCheck with kids

PreCheck is one of the best upgrades a frequently flying family can buy. The good news is that young kids usually don't need their own membership. The TSA's PreCheck for Families page says children 17 and under can use PreCheck with an eligible adult, but the rules differ by age:

• Children 12 and under can go through the PreCheck lane with a parent or guardian whose boarding pass has the PreCheck indicator. The child's own boarding pass doesn't need to show it.
• Teens 13 to 17 can use the PreCheck lane only if the indicator appears on their boarding pass. To make that happen, the teen and the PreCheck adult must be on the same airline reservation, and the adult's pass must show PreCheck. If the teen doesn't have their own Known Traveler Number, leave that field blank. Don't enter the parent's number.
• Separate reservations break it. If your teen is booked on a different reservation and has no KTN of their own, the TSA says they won't get PreCheck screening.
• Kids who fly alone often should get their own PreCheck or another DHS trusted traveler membership.

In a PreCheck lane, the TSA says you don't need to remove shoes, laptops, 3-1-1 liquids, light jackets or belts. As of October 2026, the TSA is also advertising a family enrollment discount: $15 off the second enrollment when two first-time applicants sign up together at the same location and time (its example: a family of four can save $30), for enrollments completed by December 31.

Family lanes and kid-friendly screening

The TSA runs dedicated "Families on the Fly" lanes for parents travelling with children 12 and under. As of this writing, its list of airports with these lanes includes Charleston (SC), Charlotte, Honolulu, Jacksonville, Columbus (OH), Orange County/John Wayne, San Juan, Oklahoma City, Orlando, Providence, Salt Lake City, Seattle-Tacoma and Tampa. Look for signs at the checkpoint, and check the TSA page for additions.

Wherever you fly, the TSA's rules for screening children are designed to keep things calm:

• Children who appear to be 12 or younger get modified screening meant to reduce the chance of a pat-down. Kids 13 and older get standard screening.
• Children will not be separated from their parent or guardian.
• You'll take infants and small children out of strollers and car seats and carry them through the metal detector. Strollers, car seats, booster seats and baby carriers go through the X-ray.
• If your child has a disability or medical condition, tell the officer. TSA Cares takes calls at (855) 787-2227; the TSA's families page suggests calling at least 72 hours before your flight.

A pre-trip security checklist for parents

• Every adult (18+) has a REAL ID, passport or other acceptable ID, and it's not a temporary license
• Any teen turning 18 before the trip has their own acceptable ID
• Anyone without acceptable ID has prepaid TSA ConfirmID on Pay.gov and saved the receipt
• Kids and PreCheck adults are booked on the same reservation, with teens' KTN fields left blank unless they have their own
• A copy of your lap infant's birth certificate or passport is in the diaper bag
• Formula, breast milk and baby food are packed where you can pull them out quickly at screening
• Each adult's 3-1-1 liquids are in a quart-size bag; medicines are ready to declare
• You've checked whether your airport has a Families on the Fly lane

Most of the 2026 changes take minutes to sort out at home and much longer at the airport. Some parents keep IDs, confirmation numbers and a checklist like this one in a shared trip planner so both adults can see what's done. Walk up with the right documents and the formula ready to declare, and all you have to handle is the toddler.
