I suspect all the benefits are oriented strictly to those living in Spain (or more accurately, Madrid). I know nothing about the unpublished benefits, but I remember that one of the published benefits was free preferential parking at MAD airport, with valet service and things like free car wash. Rather interestingly LH also offers something like that, but at their HON level (earned status that is roughly BA Premier equivalent, quite a bit harder to get than Emerald). QF used to send 6 bottles of wine for Christmas presents, but that was a few years ago. Maybe IB is sending some iberico ham.
