A plan to add more flights between Plattsburgh International Airport and Boston could mean a loss of customers for Burlington International Airport.

Plattsburgh is poised to receive over $2 million in federal subsidies to begin flying 34-passenger turboprops between Boston and Plattsburgh up to three times a day in the coming months. The service would be an upgrade over the nine-passenger planes currently flown by Cape Air, and could attract the Canadian passenger Burlington relies on.

The Burlington Free Press reports that adding a Boston route remains a priority for Burlington, which has not had service to Boston since Big Sky Airlines stopped flying the route two years ago.
