Why is a direct flight from Winnipeg to Calgary take longer than a direct flight from Calgary to Winnipeg?

A direct flight from Winnipeg to Calgary may take longer due to prevailing winds, specifically the jet stream, which typically flows from west to east. When flying from Winnipeg to Calgary, the aircraft may be flying against these headwinds, increasing travel time. Conversely, the flight from Calgary to Winnipeg benefits from tailwinds, helping to reduce the overall flight duration. Additionally, factors such as air traffic control routes and weather conditions can also influence flight times.
