What else could a higher *A status offer?

1) F check-in (vs. C check-in) where applicable - no big deal
2) F lounge access: this will never happen. SQ will protect their premium lounge, TG may open their doors to the F lounge (without spa access), LH/LX will never allow *pax into their FCL/FCT. They´d maintain their policy that the SEN lounges are the designated F lounges for *A flights
3) using *G lounges upon arrival or even an open-door policy would be nice, but again very unlikely to happen

Most airlines have multiple status levels that all come with *G status and it makes much more sense for the airlines to only offer certain benefits to their own (top) elites.
