United Airlines Holdings Inc. announced schedule reductions across 40 domestic airports due to directives from the FAA and DOT during the ongoing government shutdown. The adjustments, which will begin on November 7, aim to relieve pressure on the aviation system and prioritize safety. United's long-haul international and hub-to-hub flights will not be affected, with reductions focused on regional and domestic mainline routes not connecting hubs. Customers will be notified of changes and offered rebooking options, and all travelers, including those with non-refundable and basic economy tickets, are eligible for refunds if they choose not to fly.
