"We figure that this entire process will decrease the time that travelers spend in the security screening line by up to 30 percent," said TSA spokesperson Lisa Farbstein.
Authorities say two United Airlines pilots have been arrested for suspected intoxication before they were to fly 141 passengers from Scotland to New Jersey.
Significant progress has been made on shortening screening lines since earlier this spring when airlines reported thousands of frustrated passengers were missing flights, the head of the Transportation Security Administration said Tuesday.
