The latest schedule update now lists the changes for the A-300. Boston will no longer see the A-300 after November 1. BOS-SJU will now go to 3 757's and BOS-MIA will have 3 757's (1 additional 757 in Dec) and 2 737's. The 737's days at BOS are numbered as well, not sure of the schedule to move the 737's to other bases.
