Haha, I was thinking the same thing, but feeling more nervous than lucky tbh. You think UA is unlikely to correct it? I had a similar experience with an extra $100 travel certificate back in June and they never took it back despite my "Confused since this issue was resolved last week over the phone and the voucher was already received." email. My buddy still gives me crap for being honest with a billion dollar corp for a $100 gift

And yes not taking chances, I should hit gold regardless. The extra PQPs won't mean much other than hitting it a few days earlier or if the SUB only posts for next year, but the miles are a welcome plus.
