They're really doubling down on military traffic (Fayetteville & Jacksonville NC) and on the Florida Panhandle (Ft. Walton Beach,* Pensacola, and Tallahassee). However, these only account for +21 daily flights and US calls it "phase one" of its expansion; I assume that the recipients of the other 21 daily flights will be announced at a later date.
* I think airlineroute.net misread "VPS" as Valparaiso, Indiana (VPZ, which has no commercial traffic).
