Sean Duffy Pitched Idea Of A Fee To Pay For Air Traffic System On Regular Basis U.S. Transportation Secretary Sean Duffy floated the idea of charging a fee to help the Federal Aviation Administration (FAA) modernize its air traffic control system and pay for upgrades on a more regular basis, according to Bloomberg. “I would welcome an opportunity to think through, how could we have a small fee that went into allowing us to continually upgrade our systems,” Duffy said Wednesday at an event hosted by American Airlines Group Inc.
