✈️ Car Seats & Flying: What Aussie Parents Need to Know

Travelling with kids? You’ve probably already packed snacks, screens, wipes, and spare clothes, but what about the car seat?

Whether you're flying to Bali, LA, or London, car seat rules can get confusing fast. Can you bring your own? Do you have to check it? What if you're renting a car overseas?

Here’s your no-fuss guide to navigating airline policies, airport handling, and car seat rules abroad, so your trip starts safe and stress-free.

✅ Can I Bring My Car Seat on the Plane?

Most airlines do allow car seats onboard—but only under certain conditions.

Here’s what to check:

• Is your car seat approved?
  Look for stickers showing it meets Australian (AS/NZS 1754), US (FMVSS 213), or European (ECE R44/04 or R129) safety standards. Some airlines only accept FAA-approved seats.

• Does your child have a paid seat?
  You must have purchased a seat for your child to use a car seat in-flight. Lap infants (under 2 years) are not eligible.

• Is the seat forward-facing or rear-facing?
  Some airlines only permit forward-facing car seats. Check their specific policy.

📦 Do I Have to Check It In?

You’re allowed to check car seats for free with most airlines, even budget ones.

You’ve got two options:

1. Gate Check: Use the seat until boarding, then hand it over at the plane door

2. Baggage Check: Drop it at check-in—best if you don’t need it until arrival

Use a padded travel bag or box to avoid damage. Many parents swear by cheap car seat travel backpacks from Amazon or Baby Bunting.

🚗 Renting a Car Seat Overseas

Thinking of hiring a car instead?

Here’s what to know:

• Rental car companies charge $10–20 AUD/day on average for a car seat.

• Quality varies—some seats are old, worn, or not properly installed.

• Not all countries enforce car seat laws, but you should still use one, even if it’s not mandatory.

Best option?
Bring your own if you can. Or buy a travel-specific car seat (lightweight and compact) and check it in.
