The MLL Club card you can select at 35K was a couple of months late last year, at least for me. Maybe they'll fix that this year but who knows. Also, in my experience, the UA and US lounges sometimes seem perplexed by the MLL Club card and have to bang away at their computers for 5 minutes before they give you the ok to enter.

Since I was going to be only 2000 AQM short of 50k I did a quick trip to make sure I passed it. Though given the coming upgrade co-pays and flex/tango price differentials I'm not sure it was worth the time/money. YMMV.
