Boston Logan International (BOS) is the region’s main international gateway and a full-service hub for several major carriers, while smaller general aviation fields serve private and charter traffic. The airport typically hosts a mix of legacy airlines and low-cost carriers, so fares can range from premium on busy transatlantic routes to competitive on domestic hops. Logan sits just across the harbor, about 3–5 miles from downtown — travel times are usually 15–30 minutes by car depending on traffic, or roughly 20–30 minutes by the MBTA Silver Line/Blue Line and shuttle connections, with public-transit fares generally modest. Pros: convenient central location and comprehensive services; cons: can be busy with variable traffic and occasional higher peak fares.
