I will be heading to Nagoya Japan in the next few weeks. I am looking for some advice on bringing a guitar back in case I find something there. I am flying business class from Japan to Korea to the US. If I purchase a guitar do you think I will be able to carry it on? If not, would it hurt to check it in a hard case. I travel quite a bit overseas on business and first and they seem to handle the bags better (not fair but true). Any advice would be helpful.
