FAA reports highlighted potential delays from high winds in New York and Philadelphia plus isolated thunderstorms in Chicago and Indianapolis, but no widespread disruptions or ground stops. Persistent TSA staffing shortages tied to the partial DHS shutdown fueled around 3,000-6,000 delays per preliminary counts and trader consensus in related markets, yet carriers avoided mass cancellations. With near-final FlightAware stats as the resolution source, traders' 96.8% \"No\" consensus anticipates stability barring rare data revisions.",
