The terminals are connected to the central parking garage by a walkway system, and to public transportation with a free shuttle bus system. The four passenger terminals, A, B, C and E, are self-contained, each with its own ticketing, baggage claim, ground transportation service, free WiFi, and food and retail options. Surrounded by Boston Harbor on three sides, we make the most of our 1,700-acre footprint. Welcome to the primary airport serving New England, and one of the nation’s busiest airports despite operating in the second smallest footprint among the top 20 major American airports.
