I'm just concerned that the cockroach connotation that we all understand here would not mean anything to your typical Joe Flyer 'eww, what's that on his lapel' or even USAirways employees. Maybe something a bit more obvious?
I like the idea of some sort of identification for fellow USAirways Flyertalkers (since we are somewhat of a unique subgroup, with an airline that's in quite disarray but also with a much smaller group than United, for example) ..
