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.

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.
