Just a quick update. My son and I ended up getting upgraded BNA -> SFO < 24 hours before the flight (on it now). SFO -> OGG was not upgraded at the same time, but I did notice that the upgrade cleared very recently (< T24). Even more surprising, U opened up, so I immediately GGU'd my wife and daughter. We do have a set of split assignments but all's well that ends well! Thanks for all the advice upthread.
