I used MIA D30 Flagship Lounge on both 1/5 in the evening and 1/15 in the early morning (730am). Neither time was there a line on my entrance, but when I left at 915am on 1/15, there was a line out the door. Not sure how many of those folks were waiting to get verified for FL, but maybe they oughta' think about having a dedicate FL line if they are contending with AC overcrowding.
