At BWI C Gates this morning, there are no WBIs only WTMD, and women and men who set off the alarm were given a standard pat down (as reported by my husband when we watched). However, before this morning, I was reading reports that enhanced pat downs were given for WTMD alarms at other airports. It's possible that BWI C Gate has not went to the new procedures, or loosened them for the holiday travel. There's just not a definitive way to know for sure, and why I didn't fly today, even though I would've been ok, I think.
