A minor correction as I have a friend who retired as a pilot from Piedmont at the time it was acquired by US Air and he told me the story of how that happened as he was thrilled he was retiring just at the time of the acquisition because he despised US Air.
US Air was formed in the late seventies by just changing it's name from Alleghany to US Airways. They then purchased smaller more regional carriers (including Piedmont) in the mid to late 80's in order to expand its market.
