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.
If it’s meant to work like it was claimed to work at ORD, it should speed up things overall by increasing the proportion of people who get screened more akin to the PreCheck screening way.
Chicago, for example, paid for the canine teams at ORD and it did so as to cut down TSA screening delays at the airport. Thereafter, the Chicago government establishment claimed credit for the crowding/delay alleviation and credited their decision to pay for canine teams to get that apparent improvement.
