When I checked my bag Sunday at the SkyPriority counter, they had small notes sitting there related to an upcoming change to checkpoint 4. I believe the date on it was 10/10 but I am getting old and might be mistaken.
Once changed, the SkyPriority will remain on the north side where the bag check is but TSA Precheck will move to the south side of the checkpoint. This means all gen-pop fliers (not with an elite) must use a different checkpoint.
I like this change!
