Flying with KH36er

Flying to Austria on Monday for Unicon! Bringing my KH36 with me, looking for advice re: flying international

I plan on putting it in the original box it came in, but I have never flown with a bike or unicycle before. Do I need extra protection for the disc brake? Or is there some thing I have likely not considered that is important to be aware of?

I have deflated the tire and put some material in the box to minimise movement within the box.

I am flying with Scoot from Melbourne, if that is worth noting
