Safest way to transport KK S61 m2 on plane

Jhugo

Hi,

I was surprised to not find case options to fly the Komplete Kontrol 61.

I'm fairly certain they cannot be brought as a carry-on item, so I am hoping people have had experience checking their controller and made it through the flight without any damage. Can anyone recommend something apart from a custom-built flight case? Is there something else that will work that's a bit more cost-effective and not as heavy?

TIA
