“My TSA” gives you from the Transportation Security Administration (TSA).
The Transportation Security Administration’s “My TSA” iPhone app, which you can download for free through iTunes, provides real-time operating status updates for U.S. airports from the Federal Aviation Administration, allowing you to check approximate wait times at security checkpoints, flight delays, and weather conditions.
With the app you can also “share” your wait times and provide immediate feedback to the TSA concerning your checkpoint experience. The “My TSA” also includes a tool to quickly confirm whether an item is allowed in carry-on or checked baggage, plus information about ID requirements, restrictions on liquids, and tips for packing and dressing to speed up the process of going through security checkpoints.
