I already know D-E are inside security with no access to the other terminals but is G totally shut off from the other airsides. IT seems to be pretty dumpy without any lounges of any kind.
H and J are also connected. G is a dump, try to spend as little time there as possible. I still prefer it over the zoo that is AA @ MIA.
