The trial of the test that uses voluntary passenger pre-screening, is already underway at at Atlanta, Detroit, Dallas/Ft. Worth, and Miami airports. According to TSA, LAS will come on board in December for pilot participants traveling on both Delta and American Airlines. The LAX trial will begin in early 2012 for pilot participants traveling on American Airlines and MSP will come on board in early 2012 for pilot participants traveling on Delta Air Lines. TSA said public support for the program “ has been overwhelmingly positive,” adding it has received over 600 comments so far with 99% of the comments being in support of the pilot program. If this is working as well as it is at MIA, it will be very welcome at LAX!
