Journey from South Station takes 15–20 minutes depending on traffic. The Blue Line Aquarium station connects to a free water taxi ($12) across the harbor to Logan; scenic but weather-dependent.Taxis from downtown Boston cost $30–45 with the Ted Williams Tunnel toll included. Ride-hails are comparable. The Sumner and Ted Williams tunnels both serve the airport; check traffic before departing, as both frequently back up. Logan is only 3 miles from downtown but tunnel congestion often extends that to 30+ minutes.
