More than 1,000 flights have been canceled today nationwidem, and frustration is boiling over at Atlanta’s Hartsfield–Jackson Airport. Fox News’ Madison Scarpino covered on 'Fox Report' that airlines are notifying travelers early, keeping the terminal relatively calm, but anxiety remains high. Delays have already topped 4,000.“I’m very frustrated with the government… everybody’s suffering,” one traveler told Scarpino. Another added: “Fire all of them… vote them all out.” Airlines say they’ll refund or rebook affected passengers, but as Scarpino noted, everyone is hoping this gets resolved before the holiday rush. U.S. airlines canceled 1,330 flights on Saturday, the second day of FAA-mandated service reductions tied to the ongoing government shutdown, according to Reuters. FAA began enforcing 4% daily cuts on Friday, a number that will rise to 6% on Tuesday and hit 10% by Nov. 14 if the shutdown continues. On Saturday alone, 5,450 flights were delayed, after more than 7,000 delays and 1,025 cancellations on Friday. The four largest U.S. carriers: American, Delta, Southwest and United each cut roughly 700 flights as part of the FAA’s order. FAA Administrator Bryan Bedford said 20% to 40% of controllers have stopped showing up for work. Many have now missed two straight paychecks, with fatigue contributing to hundreds of voluntary safety reports from pilots, according to Sen. Ted Cruz. The shutdown, in its 39th day on Saturday, continues to strain aviation operations heading into the busy Thanksgiving travel period.
