With a move [of a carrier] to Jacksonville, do you think there will be more aircraft stationed at NAS Jax or will the CAW/CAG stay stationed at Oceana? Just curious, and forgive my ignorance for not really knowing the difference between an Air Wing and Air Group.
There's no such thing as a "Carrier Air Group" anymore. It's an outdated term which was replaced by "Carrier Air Wing," but the acronym CAG has endured, both as the name of the air wing (CVW-7, prononuced "CAG Seven") and the title of the air wing commander ("CAG Smith").
But anyway - the location of the Boats has nothing to do with where the planes are home-based. The squadrons are more or less grouped together by aircraft type. The CVWs themselves are based in Oceana and Lemoore (and CVW-5 in Japan), but that's a staff.
The "final" BRAC decision on Oceana v. re-Cecil was that the Navy should just build a new Master Jet Base somewheres else. We'll see how that works out, given that we can't even get a new OLF built in VA/NC.
The hows and whys of why Cecil was shut down in the first place (as opposed to Oceana) are shrouded in politics and mystery. There are stories of various groups pulling strings - everyone from the VB city council to SpecWar. But it happened, and the Navy had morning-after remorse, and that's how it goes.
