Do I really need to arrive 2.5 hours early if I have TSA PreCheck?

You can cut it to 2 hours if you have TSA PreCheck and are traveling only with kids under 12. PreCheck lines are usually 5-10 minutes. But if you're traveling with a teenager, a car seat, or a large stroller, stick with 2.5 hours anyway. Nothing is worse than sprinting to the gate with a tired 4-year-old.

What if my kid is sick and has medicine?

Prescription medicine in its original labeled container is allowed in carry-ons — no TSA bag required. Over-the-counter liquid medicine (like cough syrup) counts as a liquid and needs to go in your quart bag, but reasonable amounts are fine. Solid medicines like ibuprofen tablets are always allowed.

Do I have to take my baby out of their carrier through security?

The baby can stay in a soft fabric carrier (like a Solly wrap or Boba). Hard carriers need to be x-rayed. The TSA agent will tell you which. Babies do not need to be removed from wraps to go through metal detectors.

What happens if my kid refuses to go through the metal detector?

The TSA agent can do a pat-down instead. It takes longer but it works. They're used to kids refusing or being scared. Tell your kid ahead of time: 'If you're scared of the beeper machine, the officer will just check your pockets and arms.' Normalize it.

Can I bring baby wipes, sunscreen, or lotion?

Lotion, sunscreen, and other creams count as liquids and need to go in your quart bag. Baby wipes do not. You can bring full-size packs of wipes with no limit.

Should I buy TSA PreCheck if I have young kids?

If you fly 4+ times per year with kids, yes. PreCheck is $78 for 5 years. You'll save 20-30 minutes per trip when you keep shoes on and don't have to remove electronics. With kids, that time matters.

How to get through airport security with kids

Get to the airport 2.5 hours early, use TSA PreCheck if possible, pack liquids and electronics where you can reach them quickly, and keep kids entertained during the 15-20 minute security process. Plan for the fact that kids move slower and security agents will need to check car seats and strollers.

Arrive early — really early. Aim for 2.5 hours before domestic flights, 3 hours for international. With kids, security takes longer. There will be a car seat to x-ray, a stroller to collapse, shoes to remove for multiple people, and kids moving at half your normal speed. Early arrival removes the panic.
Pack smart for the security lane. Put all liquids (including milk, formula, breast milk, and juice) in a clear quart-sized bag. Put this bag where you can grab it immediately — not at the bottom of a carry-on. Remove all electronics larger than a cell phone (tablets, laptops) so they're ready to scan separately. Keep these items in an easy-access pocket or on top of your bag.
Dress kids for fast security. Dress them in slip-on shoes or sandals, not laced shoes. Avoid clothes with lots of metal snaps or buckles if possible. Skip belts. The faster they can get through the metal detector without setting it off, the faster you move. Jackets come off before the detector, so dress in layers if it's cold.
Know the car seat and stroller rules. Your car seat will go through the x-ray machine. Your stroller will be screened — either folded and x-rayed, or physically inspected. Ask the agent which. Don't take the stroller apart or remove the seat cover yourself. Let security do it. Gate-check your stroller if possible to avoid carrying it through the airport.
Handle the ID situation. You need ID. Kids under 18 traveling with an adult don't need ID for domestic flights, but the TSA can ask for proof of age. Have their birth certificate or passport ready just in case, though most kids under 12 breeze through without it. International flights: all passengers need a passport, period.
Manage the line itself. Join the regular line, not TSA PreCheck, unless you have PreCheck status. Most regular security lines move fine in the morning; afternoon lines are slower. If you have TSA PreCheck, use it — kids under 12 can go through with you. Have your boarding passes and IDs in hand before you reach the agent. Brief your kids: 'We take off our shoes, put bags on the belt, walk through the metal detector.'
Get through the metal detector. Send yourself first to show them it's fine, then send your kids. Security agents deal with kids constantly and are patient. If a kid sets off the detector, they'll pat down their hands and legs — it's quick and not scary if you tell your kid it's coming. Have younger kids empty pockets (even lint) to avoid repeat scans.
Reassemble on the other side. There's always a flat area past security. Sit down, put shoes back on kids, repack bags, reattach car seat to stroller if you brought it through. Don't try to do this while standing or moving. Take 2 minutes. Then head to your gate.
