Allegheny Airlines - September, 1979

This is a great timetable. It features Allegheny morphing into USAir, which would eventually be renamed US Airways.

From Wikipedia:
But with expansion came growing pains: by the 1970s Allegheny Airlines had the nickname "Agony Air" due to customer dissatisfaction with the carrier's service. Even after a later rebranding to "USAir", when service sometimes skidded downward, complainers sometimes dubbed the airline "Useless Air", or even worse, "USScare."
