I still don't have an answer to my previously posted questions, viz:
"At airport WL time, it seems very possible that I (as an E) could get upgraded but not my spouse (no status). From what has been posted here, I can't refuse the upgrade without paying any Y fare difference and losing my seat next to my spouse. Right? AC - not good for relationships! Can an escape clause be built in? Would a sensible GA ask me first? Can I put my spouse in the J seat instead of me?"
