The Transportation Security Administration announced that it has added two airports in the southeast to the list of facilities where participating frequent flyers can take advantage of its PreCheck expedited security screening procedures; and a Texas airport is the latest to join Customs and Border Protection’s (CBP) Global Entry program.

TSA said that PreCheck is now available at Charlotte Douglas International Airport for participating members of US Airways’ frequent flyer program, and at Tampa International for members of Delta SkyMiles. Participants in CBP’s trusted traveler programs, like Global Entry, are also eligible to be selected for the faster screening process, in which travelers may not have to remove shoes, or take laptops or liquids out of their carry-on bags.

TSA said that since PreCheck started up last fall, more than 1.7 million travelers have gone through the expedited procedure, which is now available at 18 airports for participating customers of American, Delta, Alaska, United and US Airways. Meanwhile, the St. Louis Post-Dispatch is reporting that PreCheck is expected to be available at Lambert-St. Louis International Airport sometime in the next several weeks.

Speaking of Global Entry, local media in San Antonio, Tex., are reporting that Customs and Border Protection plans to install a pair of Global Entry kiosks soon at San Antonio International Airport, making it the third airport in Texas to offer the expedited re-entry procedure for participating travelers.
