I think I need to clarify what I meant. The current Piedmont (which I'll call PI2) is the current name of Henson Aviation, a company that actually predates Piedmont Airlines (whose code was PI). The two did have a relationship in that PI2 operated flights for PI; however, the name change for Henson did not occur until many years after the PI/Allegheny (now US Airways) merger. US, by changing the name, is trying to bank on the good name of PI. http://www.piedmont-airlines.com/CoInfo.htm > <<In addition to what Michael says below, I don't believe the Piedmont of USAir > is any relation to the real Piedmont that USAir took over.
