Massena International Richards Field

This is a useful airport for clearing U.S. customs flying from Canada on a private aircraft (esp. from Ottawa or Montreal). They require only an hour notice, and if you're delayed, you can always land across the river in Cornwall, Canada, and call them to reschedule. (315) 769-3091. If you book the day before, it's a good idea to call just before you take off and remind them.
