JetBlue should be announcing the following changes soon (although unofficially leaked already):

1. More flights will be added between BOS-NYC (up to 18x/day) and BOS-DCA (up to 14x/day) for near-hourly service to both cities.
2. More flights will be added to their 12 most popular routes from Boston (AUS, CHS, ORD, CLE, DTW, BNA, EWR, MCO, PHL, RDU, DCA, and SAV) to increase the Boston market to 175 daily flights.
3. Underperforming routes DCA-BDL and DCA-TPA will be cut to reallocate the DCA slots to DCA-BOS.
