Nantucket Memorial Airport (ACK) is a public airport located on Nantucket Island, Massachusetts, serving as the primary air gateway to this historic island community. Situated approximately three miles southeast of Nantucket town, the airport handles both scheduled commercial service and significant general aviation traffic. The airport experiences pronounced seasonal fluctuations, with passenger volumes surging dramatically during the summer months when tourist demand peaks. It is owned and operated by the Town of Nantucket and plays a critical role in connecting the island to the mainland, supplementing the Steamship Authority ferry service. Due to its island location and the high cost of real estate on Nantucket, the airport is an essential infrastructure asset for year-round residents and seasonal visitors alike, handling hundreds of thousands of passengers annually.
