There have been a lot of posts in different areas about UA, AC, LH, etc. not honoring some of the perks of SA partners for pax with G and G+ status (e.g. UA 1K, AC SE, etc.)

I would like to see a thread (maybe this one) that rates all SA partners with respect to which airline really goes overboard to service FF's from their SA competitors. I hear rumous that NZ is perhaps the best of the lot. What do you think?
