Air Canada will end service to the US cities of Harrisburg, Rochester and Syracuse, effective Nov 1, the airlines confirms. "We adjusted our schedule to suspend flying to Syracuse, Rochester and Harrisburg due to the economic performance of these routes," Air Canada said. The carrier serves the 3 cities from its Toronto Pearson hub with 18-seat Beech 1900D aircraft operated by its regional partner Air Georgian. In place of direct flights, Air Canada is selling itineraries to Syracuse and Rochester that involve connections in Chicago via its codeshare with United Airlines. Executives at the carrier have talked recently of expanding their agreement with United, including a potential immunised joint venture that would allow them to coordinate service between Canada and the US. <br/>
