Direct answer: At the moment, flight cancellations are being focused in the United States at the 40 busiest airports due to a government shutdown affecting air-traffic control staffing. The plan is to reduce overall flights by about 10% at those airports, with cancellations expected to begin or be announced in the days around November 6–7, 2025, and to continue for as long as the shutdown persists or until agencies adjust safety routines. Airlines, travelers, and airports have been coordinating to implement the reductions in a controlled, safety-driven manner.
