Yes, in 2026, there is a very popular free transit option from Boston Logan International Airport to downtown. The MBTA Silver Line (SL1) bus rapid transit service is free of charge for all passengers boarding at any Logan Airport terminal heading toward South Station in downtown Boston. You do not need a ticket or a CharlieCard to board; you simply hop on the bus at the terminal curb. Once you arrive at South Station, you can also transfer for free to the Red Line subway, which provides access to Cambridge, Quincy, and other parts of the city. This initiative is part of a long-standing effort by Massport to reduce traffic congestion at the airport. Note that while the trip from the airport is free, the return trip from downtown to Logan Airport requires a standard MBTA fare. This remains the most cost-effective and efficient way for travelers to reach the heart of Boston without paying for a taxi or rideshare.
