Cape Cod Gateway Airport — Hyannis, United States

HYA is Cape Cod Gateway Airport, located in Hyannis, Massachusetts, and functioning as the main air link between Cape Cod and the Massachusetts mainland. The airport is best known for seasonal and year-round flights to Nantucket and Martha's Vineyard, making it a key connector for islanders, tourists, and commuters who prefer avoiding ferry lines during the busy summer season. HYA also serves general aviation, corporate jets, and occasional military or Coast Guard operations given its proximity to sensitive coastal areas. Passenger volume swells dramatically in summer months when Cape Cod's tourist population multiplies. The airport has operated for decades as a vital piece of regional infrastructure, particularly for medical transport and time-sensitive travel to the islands when ferries are delayed by weather.
