Update for PDX.
Checkpoint D/E has
THREE MMWs for a total of 7 lanes. The lane at the far left is clear, everything else is a MMW/WTMD pair.
Checkpoint A/B/C had one MMW when I landed Tuesday. When I left today (Thursday), a second one had been shoehorned in there. I'd suspect there will be a third one eventually. Same setup as the D/E checkpoint, except the far right lane at A/B/C right now is WTMD only.
The international arrivals checkpoint at PDX has two MMWs.
For those of you counting at home, friendly little PDX now has 7 total MMWs. I can't wait to see what happens with the lines there now.
For DCA at the DL terminal: the middle lane in the CP is MMW free. The other four lanes lead to a MMW/WTMD pair.
