16 TSA Do’s and Don’ts Families Should Know

Navigating airport security can feel like a puzzle, especially with kids in tow. The TSA lines are often the first real test of family travel patience and prep. Knowing the right moves ahead of time saves you time, stress, and those awkward moments everyone remembers. This guide lays out the key dos and don’ts to keep security checks smooth and as hassle-free as possible.
Here are 16 important tips every traveling family should keep in mind.

Do Arrive Early

Families take longer to get through security, so plan to arrive at least two hours before domestic flights and three for international. Rushing only adds stress, especially with strollers, car seats, and carry-ons to manage.

Early arrival gives you breathing room and helps avoid last-minute scrambles.

Don’t Overpack Carry-Ons

Too much stuff in your carry-ons slows down security checks. Keep only essentials like documents, snacks, and electronics easily accessible. Avoid stuffing bags to the brim; it makes unpacking at the scanner more chaotic and time-consuming.

Do Use TSA PreCheck if You Can

TSA PreCheck lets you breeze through security without removing shoes, laptops, or liquids. It’s a real game-changer for families, especially during busy travel seasons. Even if you don’t have it, consider enrolling for future trips — it’s worth the small fee and time investment.

Don’t Forget Liquids Rules

All liquids, gels, and aerosols must be in containers 3.4 ounces (100 ml) or less and fit inside a single quart-sized bag. Pack this bag on top of your carry-on for easy access. Forgetting or packing oversized containers leads to confiscations or delays.

Do Pack Baby Food and Formula Separately

Baby food, formula, and breast milk are allowed in reasonable quantities beyond the usual liquid limits. Keep these items separate and declare them at the checkpoint. This avoids surprises and smooths the screening process with little ones.

Don’t Wear Metal Jewelry

Metal items like belts, watches, and bracelets trigger the metal detector, meaning extra pat-downs and bag checks. Opt for simple, minimal jewelry on travel days. This helps speed your family’s progress through the line.

Do Prepare Kids Ahead of Time

Explain the process to kids before arriving at security so it feels less scary. Tell them they may need to take off their shoes and jackets (depending on TSA rules) and place their bags on the conveyor belt.

A little prep makes the whole process faster and calmer.

Don’t Bring Prohibited Items

Check the TSA website before packing. Sharp objects, large liquids, and many sports items are not allowed in carry-ons. Finding out you can’t bring a favorite toy or gadget at the checkpoint only causes frustration.

Do Separate Electronics

Laptops, tablets, and e-readers must be taken out and placed in bins. Have them ready in an easily accessible spot to avoid delays. Some newer machines allow electronics to stay inside carry-ons, but check your airport’s rules to be sure.

Don’t Forget Stroller and Car Seat Procedures

Strollers and car seats need to be screened separately. Be prepared to fold strollers and place them on the conveyor belt. Gate-checking these items is an option, but plan so you’re not surprised.

Do Dress for Easy Removal

Shoes, jackets, and belts must be removed before screening. Wearing slip-on shoes and simple layers helps keep lines moving. Complicated outfits only add time and fuss.

Don’t Hold Up the Line

If a bag needs extra screening, move to the side quickly to avoid holding up others. Stay calm and cooperative with TSA officers — they’re there to keep you safe. Quick cooperation helps everyone get through faster.

Do Use Clear, Labeled Bags for Medications

Keep prescription medications in their original packaging and place them in a clear bag for inspection. Liquid medications are allowed in larger amounts but must be declared separately. Declare them to the officer when you reach the scanner. This reduces questions and speeds up your passage.

Don’t Leave Bags Unattended

Always keep an eye on your belongings. Airports are busy places, and unattended bags raise security concerns. Assign a responsible adult to watch the items or take turns in the family line.

If you have questions or special needs, don’t hesitate to ask TSA staff. Many airports offer assistance for families, seniors, or travelers with disabilities. Getting help early prevents confusion and delays.

Don’t Forget to Reclaim All Your Stuff

After screening, check you’ve collected all your bags, shoes, and belongings. It’s easy to forget jackets or laptops when rushing to the gate. A quick second look saves scrambling later.

Keeping Security Stress Low

Security checks don’t have to feel like an obstacle course for families. With preparation, patience, and the right approach, they become just another step in the travel adventure. Knowing what to do — and what to avoid — makes the process faster and easier for everyone.

Travel starts best when you glide through security with confidence and calm.
