The A319s will shift back to the domestic hub and spoke system and appear on the following:

-JFK-BOS: 4x daily and cancel the 6x daily OH CRJ-900 flights
-LGA-JAX: Equipment upgrade
-LGA-PWM: Replace an OH CRJ-900
-DTW-DFW: Upgrade a CRJ-900 flight
-DTW-MCI: Upgrade a CRJ-900 flight
-ATL-ORD/LIT/HOU: Upgrade one flight each
