Reading back through this thread, it sounds like splitting is the best way to use a GPU for two pax, since R=1 a lot of time. I'm a 1K and my GF is a Silver.

We've already cleared on the outbound, so I assume no issue with splitting.

A few questions:

1) For the return, we've got two legs on LH connecting to LHR-SFO. Is there any downside to splitting related to the LH legs?

2) Will my GF keep the advanced E+ on the LHR-SFO in coach unless one of us gets upgraded?

3) Even with splitting, my Silver GF will have 1K priority for the GPU, correct?

Thanks in advance.
