Terminal B, AA side at BOS still as posted with WTMD and BKSX paired. However, today Jan. 7, 2012 lanes were split so each WTMD and BKSX was fed by a separate lane. TSA was directing between lanes to either WTMD or BKSX as needed, but picking the lane that lined directly into the WTMD had a higher chance (far better than 50% since BKSX was taking longer) of getting the WTMD. Worked for me this morning. A semi-SDOO? YMMV as always!
