I expect to do some airplane travel and in some cases may be able to put my guitar overhead, but sometimes might have to gate check. I have a polyfoam case for my Godin guitar and it's small enough to sometimes fit overhead, but is reasonable protection wise in the event I need to gate check. Would appreciate a recommendation for a case that is gate checkable, but that could go overhead. My P-03 came with a hardshell case, and it's small, but it would better if I had something smaller and lighter.
