The airport sits just across Boston Harbor, about 3–5 miles from downtown; travel options include the MBTA Silver Line bus (25–35 minutes, low single-digit fares), Blue Line + shuttle (20–30 minutes), taxis or rideshares (15–25 minutes, fares varying with traffic), and express shuttles. Pros: strong connectivity and frequent flights; cons: congestion, occasional delays, and airport fees that can add to ticket cost.
