Will try to see what data we can pull on how many passengers with a KTN utilize TSA Pre✓™ each day.
Regarding our program, the one that began Dec. 4, 2013: 375,584 travelers have enrolled as of COB yesterday. We have 266 off-airport locations, 27 on-airport locations at 25 airports; ATL/LAX have two locations.
That does not include CBP programs (Global Entry, NEXUS and/or SENTRI). I believe Global Entry has over 2.5 million members, but Global Entry began 2008.
