I am assuming you mean suite upgrade, and as it isn't a part of the program bennies, they are few and far between.

I am a LT Plat, have been for several years, but there are still times I do not get the CL floor. And I can count on fingers and toes the number of suite upgrades I have received. Of course, I rarely ask - so probably could have scored more, but don't care enough about them to do so.
