High Quality Content by WIKIPEDIA articles! Odyssey International (IATA: OL, ICAO: ODY, Callsign: Odyssey) was an Charter Airlines airline based in Toronto, Canada. Odyssey International can trace its origins to Owen Sound Air Services (OSAS) founded in 1973 as a flying school and charter airline. Over the years OSAS grew by flying cargo for Purolator and also using Douglas DC-3 for Airborne Express ad Emery. In 1984 OSAS was taken over by Soundair (who remained the parent company throughout the years). Soundair also took over Aero Trades Western and used the DC-3s and also Douglas DC-4. Two years later Convair CV-580 replaced the DC-4s and also the DC-3s were disposed of in favor of the Fokker F27 Friendship.
