Details
- TSA rules: Car seats are permitted through security. They must be screened, either by X-ray (if small) or manual inspection.
- In the cabin:
- If your child has a paid seat, you can install an FAA-approved car seat in that seat.
- The car seat must have a label reading “This restraint is certified for use in motor vehicles and aircraft.”
- Car seats are typically used in window seats, not aisles or exit rows.
- Gate-check / counter check:
- Airlines allow you to check a car seat for free at the ticket counter or gate.
- If gate-checked, you’ll pick it up at the aircraft door after landing.
- International flights: Most foreign carriers also allow car seats, but rules about cabin use can vary.

Gotchas / Common Issues
- ✈️ Seat purchased = cabin use: You must buy a ticket for your child if you want to use a car seat on board. Lap infants cannot use car seats in seats you don’t pay for.
- ✈️ Label required: Without the FAA approval sticker, flight attendants may refuse the car seat.
- ✈️ Size matters: If the car seat is too wide for the airplane seat, you may be required to gate-check it.
- ✈️ Protect when checking: Use a padded car seat bag to prevent damage if you check or gate-check.
