If you’re flying with Qantas, you might be asking just how strict they are with carry-on luggage.
The airline has specific rules regarding size and weight limits, and they do enforce them most of the time.
If your bag doesn’t fit in the overhead bin or under the seat in front of you, there’s a good chance you’ll have to check it in possibly with an extra fee.
To help you prepare, I’ve put together this guide covering everything you need to know about Qantas carry-on allowances, what to do if your bag is too big, and some handy tips to make your travel smoother.
Let’s dive in.

Qantas is fairly generous with its baggage policies, but it’s important to stay within the limits to avoid surprises at the airport.
Here are some key things to keep in mind:
- Always carry essential medications and prescriptions in your carry-on.
- Keep your bag as light as possible airports can involve a lot of walking, and cabin space is limited.
- Pack fragile or valuable items securely.
- Your bag must fit under the seat in front of you or in an overhead locker.
- Ensure your luggage complies with carry-on size limits (details below).
- Dangerous goods are not allowed unless explicitly permitted.

Final Thoughts
While Qantas offers generous baggage allowances, they do emphasize to stay within their luggage size.
If your carry-on exceeds the allowed size or weight, you may need to check it in or pay an excess baggage fee.
Double check your luggage size and weight before you leave for the airport.
You don’t want to deal with any last minute hassle.
Keeping essentials in your carry-on and considering extra baggage options in advance can help make your journey smoother.
I hope this helps.
Happy travels.
