From another website, some guy has gone through the newly loaded spring schedule to find the new LGA destinations from the slot swap ( a lot of former USairways stuff). I'm sure everyone notices the same thing that I do about the list:

LGA-MIA 4x M88
LGA-BTV 3x (2x OH CR7, 1x ERJ)
LGA-ROC 4x CR7 (OH)

LGA-SYR 5x (4x ERJ, 1x CR7)
LGA-RIC 5x (4x ERJ, 1x CRJ)
LGA-MHT 2x ERJ
LGA-SDF 1x ERJ
LGA-GSO 3x ERJ
LGA-ORF 4x ERJ
