I am a first time user of KVS and subscribed last week. I have looked through the docs, signed up for the ANA account, but am not having luck doing the following:

Search for upgrade availability on UA, from coach to business class, using a GPU on an eligible fare (ie W class or higher).

These are the parameters I have used:

Awards/Upgrades
Method: Awards/StarAlliance
From: AUS
To: HKG
Date: April 15, 2014
Airlines: *A Star Alliance (All 31 Member Airlines)
POS: JP-ANA-SP1
Sort By: Connections
Seats: 1

Filter
Filter Results: Yes
Availability Required in Class(es): R

Power Search
Date: 16 Apr 2014
Range: 14 Days

I have not gotten any results. What am I doing wrong or overlooking? Is 'R' the correct class to be searching for?
A PM would be great, or direction to a particular post # in this forum as I am feel my question is probably a common one.

Thanks in advance!
