Some news tidbits posted on the IAH website about GE:

U.S. Customs and Border Protection (CBP) recently announced that one million people have been given the ‘trusted traveler’ designation through the Global Entry program. ...
....In June 2008, George Bush Intercontinental Airport (IAH) was chosen as one of the first airports in the nation to launch the program and has now enrolled more than 90,000 travelers....
.....IAH consistently ranks in the top three for program enrollment and kiosk usage among airports in the nation. Enrollments in 2013 have increased 75 percent over last year....
IAH was tops in enrollment a couple of years ago (makes sense being one of the first three airports for GE) but is still in the top 3.
Curious as to what the other top two are. Any guesses? IAD and JFK? MIA and LAX?
