I haven't been very fond of USAir since they bought out Piedmont. Flying Piedmont was always a pleasure. Having to fly USair on the same routes sucked out loud.
Riding a Martin 404 or an F-27 through the mountains on a cold, stormy night could be something other than a pleasure. They had air sikness bags for a reason. They did have nice folks, as did Southern, but so did Delta in those days. Too bad they all got yankeefied.
