Bike box for Airnimal Chameleon

careful

I am thinking of buying an Airnimal Chameleon but I am having trouble sourcing a suitable sized hard case mainly for air travel. The Airnimal cases seem to be unobtainable. There are plenty of hard suitcases that are long & deep enough, but none are wide enough to accomodate the 24" wheels (I guess about 26" dia including tyres). Any ideas?
