One Stop Security, Delta’s new airport program, could change the way we travel. The initiative is designed to allow passengers to bypass redundant security checks—ultimately enabling them to proceed directly to their gate, as they would for a domestic connection, rather than having to pick up and recheck their bags and go back through TSA after landing in U.S. The process is said to save travelers up to 45 minutes... but does it actually work? Right now, this has been rolled out for customers flying from London’s Heathrow Airport (LHR) and connecting through Hartsfield-Jackson Atlanta International Airport (ATL) to a domestic destination.
