Hello. It looks like I'm going to have to make a couple long-haul trips by airplane in the next year, and I'll probably be away from home for a few months at a time. I'll probably be taking my brand new swallow concertina along for the ride, since the alternative is leaving it in a hot, humid, moldy tropical summer for a few months. Are there any special precautions I should be taking when travelling with a concertina by plane? I plan to treat it like any other piece of valuable luggage (take it as a carry on in a hard case, store it on the seat next to me, etc...), but should I be worried about stuff like the humidity in the dry airplane, or the regular bumps and jostles associated with putting something through airport security? As a new player, I don't quite have a handle on what kinds of treatment these instruments can handle.
