Comment thread ""Montreal's US airport"" for Plattsburgh International Airport

Plattsburgh International (a former air force base) is 100 km from downtown Montreal (Canada), and draws heavily on Montreal for its airline business. Several carriers, including Allegiant and Xtra, offer flights to destinations like Myrtle Beach, SC and Niagara Falls, NY. General aviation has moved here from nearby Clinton County (PLB), which has mostly shut down.
