Flying out of Boston Logan International Airport (BOS)? The next time you take public transportation to the airport, you might get to skip the long security lines. A new concept at BOS plans to trial a form of "presecurity" for users of the greater region's Logan Express bus service. The trial would take place at the Logan Express station in Framingham starting in June, according to The Boston Globe, which first reported plans for the presecurity program. Depending on how the trial goes, the service could expand to the rest of the Logan Express lines, including Braintree, Woburn and the Boston Seaport.
