Traveling with children requires careful preparation to avoid last-minute scrambling. This family travel checklist covers every essential step, from passports and car seats to medications and entertainment, so you can leave home confident that everything is in order. Use this guide alongside the detailed Family Travel Checklist for more in-depth packing lists.
Documents and Identification
Start with the most critical paperwork. For international travel, every traveler — including infants — needs a valid passport. Apply well ahead of your trip, as processing times vary. Check the destination country’s entry requirements; some require that a child’s passport be valid for a certain period beyond the travel dates. The State Department traveler’s checklist provides up-to-date information on documentation needed for minors.
If your child is traveling with only one parent or a guardian, many countries require a notarized letter of consent from the non-traveling parent. Check the U.S. State Department’s page for the specific country’s rules. Also, consider enrolling in the Smart Traveler Enrollment Program (STEP) to receive safety alerts and make it easier for the embassy to contact you in an emergency.
For domestic flights, a REAL ID-compliant driver’s license or other acceptable identification has been required since May 7, 2025. Children under 18 generally do not need ID for domestic flights when traveling with an adult, but check the TSA REAL ID page for the latest guidance. It is always wise to carry a copy of your child’s birth certificate or passport as a backup.
Booking and Seating
Book seats together as early as possible. While some airlines automatically seat families together, policies vary. Confirm your seat assignments before the day of travel. If seats cannot be arranged together in advance, speak with gate staff at the airport — they often help families sit together when possible.
If you plan to bring a car seat on the plane, it must have a label stating it is certified for use in aircraft. Check the car seat’s manual or look for “This restraint is certified for use in motor vehicles and aircraft” on the label. Many car seats are certified for aircraft use, but booster seats are not. Check the FAA’s guidance on car seats and the airline’s specific policy. For rental cars at your destination, you can either bring your own car seat (check it as baggage or gate-check it) or reserve one through the rental agency. Reserve early, as availability can be limited, and verify that the seat meets safety standards. The NHTSA car seat guidance explains how to choose and install car seats.
Health and Medications
Schedule a pediatrician visit at least a few weeks before departure. Discuss any recommended vaccinations for your destination, and get prescriptions for any medications your children take. Ask about motion sickness remedies or altitude adjustments if relevant. Pack a travel health kit as described in the CDC Pack Smart travel health kit guidance. Include any fever reducers, antihistamines, allergy medicine, and electrolyte packets.
Pack all medications in their original containers and bring copies of written prescriptions. For liquid medications, they are exempt from the standard 3.4-ounce (100 ml) liquid rule, but you must declare them at the security checkpoint. The TSA liquids rule page explains what you can bring. Also check the TSA What Can I Bring tool for specific items like nasal sprays or hand sanitizer.
Home Preparation
Before you leave, take care of your home to ensure peace of mind. Stop mail and newspaper delivery, or ask a neighbor to collect them. Arrange for pet care either at home or at a boarding facility. Set timers on lights to make the house look occupied. Lock all windows and doors, and if you have a security system, test it and arm it before departure. Leave a copy of your itinerary and emergency contact numbers with a trusted neighbor or family member.
Packing for Each Child
Organize each child’s belongings in a separate compartment or bag. A kids travel organizer helps keep small items like pacifiers, socks, and toys accessible during travel. Use packing cubes to compress clothes and keep outfits for each day together. For each child, include:
- Complete change of clothes (plus an extra) in the carry-on, including underwear and socks.
- Comfort items such as a favorite stuffed animal or blanket.
- Toiletries: sunscreen, baby wipes, diaper cream, toothbrush and toothpaste.
- If the child uses a sleep aid like a white noise machine, bring a travel-friendly version (battery-powered or USB).
Consider each child’s age and needs when packing; younger children require more diapering supplies, while older ones may need chargers for their devices.
Entertainment and Snacks
No family trip goes smoothly without a good supply of entertainment and snacks. Pack screen devices preloaded with movies, games, and downloaded content (wi-fi is not always available). Bring child-safe headphones and portable chargers. Spare lithium batteries and power banks must be in carry-on baggage, not checked luggage, per FAA PackSafe lithium batteries guidance.
For offline activities, include coloring books, sticker books, magnetic travel games, and a small new toy (the novelty helps keep attention). Snacks: choose non-perishable items that do not exceed the TSA liquid limit for individual items. Pack granola bars, dried fruit, crackers, pouched applesauce (under 3.4 ounces each, or buy after security). Avoid strong-smelling foods out of consideration for other travelers.
The Day Before Travel
Use the day before your flight to finalize everything:
- Confirm your flight time and check in online. Download boarding passes or print them at home.
- Call the airline to verify seat assignments, especially if you were not seated together.
- Charge all phones, tablets, laptops, and power banks. Download any necessary entertainment for offline viewing.
- Pack your carry-on bag with items you will need on the plane: snacks, medications, entertainment, a change of clothes for each child, and toiletries.
- Lay out clothes for everyone for the next day, including shoes and jackets. Check the weather at both departure and destination to dress appropriately.
- Prepare a small bag for car keys, boarding passes, IDs, and passports so you can grab them quickly on the way out.
Getting a good night’s sleep is important; try to stick to your usual bedtime routine as much as possible.
