VeriFLY is a free new travel experience being offered at Denver Airport, which allows you to reserve TSA screening in advance of your flight and will give you access to an expedited security lane and a reserved train car connecting the airport’s three concourses, A, B and C. You will be required to fill out a brief health questionnaire before traveling. Simply create an account on the VeriFLY app to book a 15min security window up to two weeks before your travel date.
