As a skymiles PM and weekly traveler out of bos, I was horrified at the recent TSA changes made at the A terminal security lines yesterday. The TSA in all their wisdom implemented their new "ski slope" (black diamond, blue square, green circle) security line process and by doing so removed/merged the delta medallion security line with the black diamond line. Now this line is open to all levels of "expert" travelers and as a result the line almost reached out the door of the terminal. Anyone know if this is a permanent change, or if the dedicated delta medallion security line will return?
