I traveled within Europe with my OneWheel+ as checked luggage. I was using a Pelican Case 1650 which is very heavy. Without foam, the board in the case weighed about 23,5 kg, which was just a little over the maximum weight for checked luggage in the economy class - but the 500g were within the tolerance. Last week, I got the "Neewer Roller Bag" (Search for B06XMYZLS9 on amazon) which is approximately 5 kg lighter and leaves some room for packing in charger, helmet and other stuff that I had to carry as cabin luggage last time. I have not tried to have the OneWheel as cabin luggage. I guess it is too heavy (>8kg) and too big for this.
