TSA’s security in AA’s terminal two is now implementing a dog check program that wasn’t here a few days ago. There is an additional snaking line to walk twice past sniffer dogs. Clear told me it was added this week. It causes a horrendous length line into the terminal open area, but it moves pretty fast as the dogs don’t seem to find anything they need to look at. Clear clients get run through the line too, but get to do a partial cut. My guess is this procedure adds 10 minutes to the morning checkin for regular TSA precheck folks.
