Well, I'm still holding just two D seats LAX-SJC, and three D seats SJC-LAX. A week or so has gone by since I got AA to split the PNR and grab those seats, and the third south-bound seat that I need hasn't magically appeared.

Unfortunately, the flight appears to be pretty full - about the only thing on offer is Y1 in the cheap seats. The front shows J7. I suppose that doesn't give the revenuers much incentive to give me one more D, but is there any useful strategy for shaking the seat-tree?
