in response to the travel restrictions; a few years back I took both a small rucksack and my full sized guitar with a hard case on as hand luggage to Thailand (a heavy, bulky bit of kit) and apart from a few odd looks from airport officials was fine. No problems at all.
However wouldn't recommend it for travelling. On this trip I was living in a fairly comfortable, secure hotel for the duration and would just leave my guitar in my room. Couldn't imagine having to lug it around everywhere!
May have to get myself a smaller one for my up and coming trip. Anyone have any links for some good ones? Couldn't last more than a couple of months without playing!

Djembe. Where theres a drum, theres a circle. And circular formations allow for the flow of energy to much more easily pass by. It just makes sense!
I bought a full sized Djembe in Cuzco and lugged it all the way to Buenos Aires before finally giving it away to some hippies in San Telmo for some small herbal remedy! It was great, but as frequently as people loved it, I would also have my neighbors in hostels on the verge of smashing it over my head (I never played at night). It was a pain in the butt on bus trips though, no matter how many times I asked to keep it on top of all the luggage, it always ended up on the bottom.
