Nantucket is one of the most dog friendly vacation spots in the United States. Dogs are welcomed everywhere, including in restaurants with outside tables, the beach, and all of the parks on island. Dogs always travel for free both on the ferries to the island, and on commuter airplanes from Hyannis. 

When our dog, Buck, was still alive, we really enjoyed his company on the flight from Hyannis to Nantucket. He will sit in the back and put his nose to the window and enjoy the ride. It was truly wonderful to know that he was always welcomed, he always travel for free, and fellow travelers welcomed his company.
