Apollo had a category on the Departure Management list (BP0) which listed passengers who seats had been changed or no longer had a seat. Thus the GA new who was affected by the equipment change. Now in the post 3/3 era equip changes are done by automation in Houston and if there is any equivalent to the BP0 list we GAs haven't been given the secret code to access it thus the announcement, "to go the counter if the BP doesn't scan".

GAs are often the last to be notified of an equipment changes. C'est la gare.
