Cape Air has a large fleet of Cessna twins and a smaller number of Islanders operating locally from a diverse set of locations across the US, including Billings MT, Boston, Hyannis, Martha's Vineyard, Nantucket and San Juan. From 2019 they started receiving the first of an order for 70 Tecnam P2012s, designed and built in Italy around Cape Air's Cessna replacement requirement. Their HQ is at Hyannis Cape Cod Gateway Airport, where I found one of the 30 delivered so far.
