DALLAS (AP) — Backups are easing at U.S. airports thanks to a break in the weather, but travelers are still seeing large numbers of flight delays. United Airlines is struggling more than others. United was accounting for the majority of canceled flights in the U.S. on Thursday. The CEO of United blames a shortage of air traffic controllers, especially in the New York City area. Transportation Secretary Pete Buttigieg concedes there is a shortage of controllers, but he says United has some internal issues that aren’t happening at other airlines.
