Airlines participating in TSA Pre-Check are sending emails to frequent fliers asking them to opt in to a volunteer pre-screen program that allows you to skip the long security lines.
You can participate if you are flying Delta out of Atlanta, Detroit, Las Vegas, or Minneapolis or on American Airlines out of Dallas, Las Vegas, Miami, LA, or Minneapolis airports.
The program will be added for Delta passengers flying out of Salt Lake City on February 14th and American at JFK on February 28th.
In March, the program expands even more this time to Ronald Reagan Airport if you are flying on Delta and American Airlines in Chicago.
In 2012, participating airlines at the following airports will join the program: Baltimore / Washington International, Boston, Charlotte, Cincinnati, Denver, Fort Lauderdale, George Bush, Honolulu, Indianapolis, JFK, LaGuardia, St. Louis Lambert, New Orleans, Luis Munoz Marin International, Newark, Chicago O’Hare, Orlando, Philadelphia, Phoenix, Pittsburgh, Portland, Ronald Reagan Washington, Salt Lake City, San Francisco, Seattle, Tampa, Anchorage, and Washington Dulles.
While this program aims to expedite security, TSA says it’s not a guarantee. To prevent terrorist acts, there needs to be a certain amount of randomness and unpredictability. A barcode will be embedded on your boarding pass if you are eligible for expedited security and volunteered previously.
