I just updated the directions in the wiki to include advice about getting from the lounge to the D concourse. I think your fastest route is to walk all the way from the lounge to the A concourse and take the mobile lounge from there, but if somebody's found that it's faster to take the Aerotrain back to the main terminal and then get ona mobile lounge to D, edit away!
