Windsor International Airport — Windsor, Canada

Windsor International Airport, designated YQG, serves Windsor, Ontario, a major border city located directly across the river from Detroit, Michigan. As one of the busier airports in this list, YQG offers scheduled commercial flights to destinations including Toronto, supporting the region's automotive manufacturing industry and cross-border trade relationships. The airport features a well-developed terminal and paved runways capable of accommodating regional jets.
