Transportation Secretary Sean Duffy on Wednesday ordered 10% flight cuts to start on Friday at 40 major US airports, including in New York, Los Angeles and Chicago, affecting both commercial and cargo services. The FAA cited a safety assessment of air traffic controllers in ordering the unprecedented cuts, but officials insisted it is safe. FAA Administrator Bryan Bedford reiterated on Thursday that the agency would not hesitate to take further action to make sure air travel remains safe. During the closure, 13,000 air traffic controllers and 50,000 security screeners have been forced to work without pay. But even before the new flight cuts went into effect, customers said flight delays and cancellations were causing misery.
