Logan International Airport

Boston Logan International is New England's dominant gateway and the largest airport in the six-state region by a wide margin, handling 40.4M passengers (2024) across 173 destinations on 76 airlines. Logan's unusual position — built on infill islands in Boston Harbor, a two-mile subway ride from downtown — gives it the shortest city-center access of any major U.S. airport, with the airfield literally visible from the North End's waterfront. JetBlue operates its largest hub at BOS with 200+ daily departures, while Delta runs a sizable focus-city operation and American, United, and Southwest maintain meaningful shares. Transatlantic capacity is the airport's distinctive strength: BOS is the primary U.S. eastern gateway for Aer Lingus, a significant station for British Airways, Lufthansa, Air France, and KLM, and hosts nonstop service to most major European capitals as well as Reykjavík, Doha, Dubai, Tel Aviv, and Tokyo. Four terminals (A, B, C, E) connect via airside and landside transit, with Terminal E handling international arrivals through a 21-gate federal inspection facility. Logan's six runways include three parallel/crossing primary strips — 15R/33L at 10,083 ft (3,073 m), 04R/22L at 10,006 ft (3,050 m), and 04L/22R — plus the controversial 14/32 runway opened in 2006 after decades of litigation to address chronic northwest-wind backups. The airport sits at 20 ft (6 m) elevation on 2,384 acres (965 ha) of reclaimed tidal flat and requires constant seawall and runway-end reinforcement as Boston's sea-level rise accelerates. Massport's Silver Line bus tunnel and Blue Line subway connections make BOS one of the most transit-accessible airports in North America.
