Due to the 1929 economic depression and having no U.S. Mail contracts, Pittsburgh Airways was forced to end operations. Per a newspaper article, its assets were sold to Atlantic Airways of York, PA (mainly office equipment and airplane equipment) for $2500.00. This amount seems rather low so logic would  suggest that the remaining aircraft weren’t included, maybe were on lease, or sold separately. There was an attempted merge with Ohio Air Transport, Southwest Air Fast Express and United States Airways but the deal fell through. Had the four companies merged, they were going to name it United Aviation. Too much competition from TWA, the old TAT-WAE, (Transcontinental and Western Air Inc.), who had the U.S. Mail contracts aborted this venture.
