Dulles International is the first airport in the country to debut a system that automatically calculates wait times at the Main Terminal's east and west security mezzanine checkpoints. The wait times are displayed in real time in the terminal and on the Airports Authority's website for desktop and mobile devices. Since both mezzanines are connected beyond security, passengers have the option to select the line with the shorter wait.
Reagan National was among the first airports in the country to debut TSA Pre-Check. This program opens expedited screening lanes to frequent flyers of Delta, Alaska and US Airways, active members of the U.S. military who show their "CAC" (Common Access Card) at the checkpoint and passengers enrolled in "Global Entry."
