Input: Question: How many more passengers could fly on the Dash 7 compared with the Fokker F27 Friendship? Passage:Time Air was a regional airline that initiated operations in Lethbridge. Founded in 1966 as Lethbridge Air Service, Time Air flew a variety of turboprop aircraft and also operated jet service as well with Fokker F28 Fellowship twin jets. In February1976, the Official Airline Guide (OAG) listed up to eight round trip flights a day operated by Time Air nonstop between Lethbridge and Calgary with Fokker F27 Friendship and de Havilland Twin Otter turboprops. According to the November15, 1979 edition of the OAG, Time Air was operating up to ten flights a day nonstop to Calgary with DHC-6 Twin Otter and Short330 turboprop aircraft. By April1985, the airline was operating larger Dash7 turboprops on the Lethbridge-Calgary route in addition to the Short330 aircraft with up to nine flights a day. In 1995, Time Air was flying the Fokker F28 twin jet on a daily basis between Calgary and Lethbridge in addition to other flights operated on the route with Dash8 turboprops. This appears to have been one of the few times that Lethbridge had scheduled passenger jet service. Time Air was also flying at this time as a Canadian Partner air carrier as part of a code sharing agreement with Canadian Airlines International (formerly CP Air). There was also competition on the Lethbridge-Calgary route at this time as Air BC was operating Dash8 turboprops as an Air Canada Connector air carrier via a code sharing agreement with Air Canada. Air BC also operated British Aerospace BAe Jetstream 31 between Lethbridge and Calgary at one point. Time Air operated other flights as well from Lethbridge including direct service to Vancouver via an intermediate stop in either Kelowna or Penticton, British Columbia during the 1980s and also nonstop service in 1988 to Great Falls, Montana. In 1993, Time Air and Ontario Express began operating as Canadian Regional Airlines on behalf of Canadian Airlines International which then eventually acquired Time Air and merged the airline with Ontario Express. By 1999, Time Air was operating Dash8 turboprops as well as Fairchild Swearingen Metroliner on its flights to Calgary as Canadian Regional while Alberta Citylink was flying BAe Jetstream 31 turboprops on its services to Calgary as Air Canada Connector.

Output:
In February1976, the Official Airline Guide (OAG) listed up to eight round trip flights a day operated by Time Air nonstop between Lethbridge and Calgary with Fokker F27 Friendship and de Havilland Twin Otter turboprops
