I am doing UA 930 on 9/24, and looking for a Y to C upgrade (I am a 1k mm). On seatcounter, it does not look good (F0 C0 Y3...). Anyone else have experience lately how this flight shakes out in the end? It is a 747, and I would have thought that with 73 C seats, there would be a reasonable chance....But then, SFO probably has more GS than anywhere else.
