I'm not disputing a thing you wrote here, but just FYI, I don't get the same page you do.
Under the heading of Explore all the Hilton HHonors Surpass Card can do for you
and then choosing Travel Benefits, I have to click to expand to see more benefits and the one with superscript 8 has Travel Agents On Call. In fact, the Priority Pass benefit doesn't even appear to be mentioned on the page I was taken to.
My point is this was very poorly documented. I have in my hand the documentation that came with the card. It isn't mentioned anywhere that you have to go through this waiting period, plus the first purchase requirement. Very frustrating!
