Transportation Secretary Sean Duffy, major airlines and other groups urged Congress on Monday to approve another $30 billion for air traffic control modernization and airport improvements. The request covers control towers, software, digital upgrades and airport facilities, following Congress’s approval of $12.5 billion over five years in June 2025 for air traffic control reforms. The push comes as the Federal Aviation Administration rolls out its Strategic Management of Airspace, Routes, and Trajectories (SMART) program, an AI tool intended to help controllers anticipate congestion and reduce delays.
