In 1956 it merged with Arctic Wings to form Transair Ltd.[1] The first scheduled route to be operated was from Winnipeg to Red Lake using a Lockheed Model 14 Super Electra.

By 1964, the airline was serving both Montreal and Ottawa in eastern Canada with scheduled weekly passenger flights operated with DC-4 aircraft to Churchill, Manitoba located on Hudson Bay via a stop in Winisk, Ontario.

By 1976 the scheduled route network extended throughout Canada from Toronto in the east to Whitehorse in the west with charter flights being operated to Europe, Mexico, the Caribbean, Hawaii, Florida and other destinations in the U.S.[4] According to the February 1976 edition of the North American Official Airline Guide (OAG), Transair was operating daily scheduled service with either Boeing 737 or Fokker F28 aircraft direct between Toronto (YYZ) and Winnipeg (YWG), with intermediate stops in Sault Ste.

Another scheduled route flown by Transair with the Boeing 737 jetliner at this time from Winnipeg served the Resolute Bay Airport (YRB) in far-northern arctic Canada.

Also, according to the OAG at this time, Transair was operating scheduled jet service with the Boeing 737 and/or Fokker F28 between its Winnipeg hub and Churchill (YYQ), Flin Flon (YFO), Gillam (YGX), Lynn Lake (YYL), The Pas (YQD), Thompson (YTH) and Yellowknife (YZF), with Whitehorse (YXY) being added by that spring.

As losses continued, the licences and routes were transferred to Pacific Western Airlines on 1 December 1979 and Transair ceased to exist.

[4] Also in 1976, Transair was operating scheduled jet service with the Boeing 737-200 and/or Fokker F28 Fellowship into those destinations noted in bold typeface:[6] According to the Official Airline Guide (OAG), by early 1979 Transair had begun operating direct one stop, no change of plane Boeing 737-200 jet service between Winnipeg and Calgary and also between Winnipeg and Edmonton (via Edmonton International Airport) with these flights making an en route intermediate stop at either Regina or Saskatoon.
