History

Allegheny before 1979

Allegheny airlines previously All American Aviation really started to grow in the 1950's. In the early 1960's they added the Convair 540 turboprop which proved to be very unreliable with many engine problems.

Shortly after they went to the General Motors/Allison Turboprops and called them theConvair 580. This proved to be a great aircraft and owns much of the credit for the airlines growth. Another source of growth for the airline in the 60's and 70's was its acquisition of Mohawk Airlines and Lake Central Airlines.

Allegheny, looking to shed its regional image, changed into Usair on October 28th,1979

Allegheny under USAir and US Airways

No longer just a regional carrier, in 1979, in a bid to break from its regional ties, Allegheny changed it's name to USAir. . Later, US Airways revived the Allegheny name for one of its wholly owned commuter operators. It flew under the trade name "US Airways Express," maintaining the Allegheny name officially in order to keep the trademark under US Airways' control. The airline was headquartered in Harrisburg, Pennsylvania and flew primarily De Havilland Canada Dash 8 turboprop aircraft serving 35 destinations in north-eastern USA, and eventually Canada, from hubs at Boston and Philadelphia. Its activities and Dash 8 fleet were incorporated into Piedmont Airlines in 2004 to consolidate operations.
