More to the point, here is the official summary of Silver benefits from the Star Alliance website. Lest there be any doubt, OP is not entitled to any of what he is talking about. This is also made clear on the AI website.
If a carrier other than AI is offering him anything beyond the two stated benefits, that is either an internal gesture having nothing to do with *A or an error.

Perhaps OP would be good enough to have the Mods remove the "Thumbs Down" from his thread title. It is unwarranted (at least for the reasons he states).
