I'd like to know how he has a better ability to secure upgrades? In my experiences with this particular person the hotels never heard of him (they just saw that it was "Virtuoso or Smartflyer", the upgrades were lacking and all the times things weren't as expected the hotel said they never heard from or of him.

All the times that there were problems I got resolution myself, and that's what I'd recommend you do by working directly with Aman henceforth.
