After 40 years in the US northeast coast seaplane market, Shoreline Aviation (1980) (New Haven) has ceased all operations and closed down on April 1, 2020, its founders said in a statement.

According to the ch-aviation schedules module, before the shutdown, the airline operated scheduled services from New York Skyports SPB and East Hampton Town, Montauk, and Provincetown. Its fleet consisted of ten Cessna (single turboprop) 208B Grand Caravan amphibians. It also operated charter and sightseeing flights.

Shoreline Aviation was the first carrier to develop scheduled services between Manhattan and the Hamptons in the 1980s.
