Montréal-Trudeau (formerly known as Dorval) handles the scheduled passenger service for Montreal. Mirabel formerly also handled scheduled passenger service, but it has been discontinued and the airport is little used. Saint-Hubert is the major general aviation reliever for the city, though Trudeau also sees a lot of general aviation traffic.
Plattsburgh International Airport in Plattsburgh, New York, markets itself as "Montreal's U.S. airport". The airport is from Montreal, and closer than Trudeau to the South Shore. More than 80% of passengers departing Plattsburgh Airport are Canadian.
