Just read on Boston.com that Massport is starting a new non-stop shuttle bus service this spring going roundtrip from Logan Airport to Copley Square and the Hynes Convention Center in the Back Bay. Didn't see an exact start date but they say it's going to be a 2-year trial. I would imagine this is going to be extremely popular. $5 per ride or free with a valid MBTA pass. I assume that would include the 7-day pass that many tourists buy but I don't know for sure.
