Boston Logan International Airport (BOS) is New England’s primary international hub, positioned remarkably close to downtown Boston across the harbor. Uniquely, the MBTA Silver Line SL1 bus rapid transit into South Station is completely FREE from the airport, including free transfers to the Red Line subway to Cambridge and Harvard University.
The best transfer deal in America is the MBTA Silver Line SL1 bus rapid transit, which is 100% FREE from all Logan Airport terminals directly to South Station in 15–20 minutes (including free transfer to the Red Line subway!). Taxis and Uber/Lyft cost $30–$45 USD via the Ted Williams Tunnel, and the scenic Boston Harbor Water Taxi costs $15.00 USD.
To reach Cambridge, the most popular way is taking the FREE Silver Line SL1 to South Station and transferring behind faregates to the Red Line subway for FREE ($0.00 USD total), reaching Kendall/MIT in 30 mins and Harvard Square in 38 mins. Taxis and Uber/Lyft cost $40–$55 USD and take 25–40 minutes.
Logan has four terminals: Terminal A (Delta), Terminal B (American, Southwest, United), Terminal C (JetBlue), and Terminal E (International). All terminals are connected by free Massport on-airport shuttle buses (Routes 22, 33, 55, 66, 88) and covered pedestrian skywalks with moving walkways.
Do not buy a CharlieTicket or subway pass at the airport if you are taking the Silver Line bus to South Station — boarding the Silver Line SL1 at any Logan terminal is 100% FREE! You only pay transit fare when traveling back toward the airport.
MBTA Silver Line and Blue Line services operate until approximately 00:30–01:00 AM. For late-night arrivals, official metered taxis and Uber/Lyft pickup zones are located in the Central Parking garage ground level.
Traveling with heavy suitcases, young children, or landing after midnight? Pre-book a fixed-price private airport transfer or express rail pass on Klook with instant confirmation and no meter haggling.
Airport Wi-Fi often drops outside the terminal curb where Uber / Lyft pickup zones are located. Install a local eSIM before your flight so you can order a ride, translate station signs, and show digital train QR tickets immediately after landing.
