Just lived here for a year but I find the security lines very easy to get through at DEN. When I moved here I had no UA status at all, I would just show my QA Platinum card and they would let me through, I was never refused. I thought this odd since I was flying UA, I think you should have to show partner status at least but it was never an issue.

Once I was flying out to LAX at the same time as a friend with no status was flying to BOS, I took him with me through the elite line without a single question so we could grab a coffee before our flights.
