Is there a 75,000 point upgrade offer?
I went for this offer online in April and within the past week or so I got the 75000 points to post to my Hilton account, within a couple days after passing the $2000 of required purchases (in the middle of a statement cycle).
But I never had a Surpass card before, so I can't comment on the OP's question, except to say that in the days of the Surpass, many people upgraded several times over the years (after downgrading back to the no-AF) and got the bonus each time, even after the lifetime language appeared on from-scratch applications. So it's not clear if the lifetime language applies to online upgrades. I guess you have to check the T&Cs carefully.
