Plattsburgh International Airport is a public airport located in Plattsburgh, New York, situated near the western shore of Lake Champlain close to the Canadian border. It serves as a regional alternative to larger upstate New York and Montreal airports, drawing passengers from both the U.S. and southern Quebec. The airport is built on the former Plattsburgh Air Force Base, which closed in 1995 following the Base Realignment and Closure (BRAC) process. Since its conversion to civilian use, the city of Plattsburgh has worked to attract commercial carriers and cargo operations to the facility. The airport features a single runway and modest terminal facilities, offering limited scheduled commercial service. Its proximity to the Canadian border — roughly 25 miles south of the Quebec boundary — gives it a cross-border catchment area that has attracted budget and charter-oriented carriers at various times.
