<p>Yes, Alleghany Airlines,which we called Agony Air for good reason.</p>
<p>Allegheny-->USAir. Indeed it was good riddance. Let's see there was also North Central, which (with Southern Air) was eaten by Republic, which was later eaten up by Northwest. </p>
<p>There was Eastern (as mentioned) which died despite having a famous astronaut as its CEO -- and it was by far the worst I ever flew on repeatedly, though I had one very memorable bad experience on PanAm shortly before it went bust.</p>
<p>We had Piedmont for a while, which was eaten by USAir -- Piedmont was a much finer deal with a cool hub in Dayton. </p>
<p>We also had NYAir flying for some years between Detroit and NY; not sure what happened to it. My favorite in old days used to be Western Airlines, "the only way to fly" according to the old TV commercials.</p>
