Airlines across the US have canceled flights scheduled for the coming days with Flight reductions in the US possibly escalating to as much as 20% if the ongoing government shutdown leads to worsening air traffic control staffing, Transportation Secretary Sean Duffy said on Fox News. The Federal Aviation Administration on Friday began implementing flight reductions at 40 key airports across the US in a bid to reduce the impact of staffing issues brought about by the shutdown. Bloomberg's George Ferguson joined Carol Massar and Tim Stenovec on 'Bloomberg Businessweek Daily' to break it down.
