A severe winter storm sweeping across much of the United States has caused major travel chaos, forcing over 14,000 flight cancellations across the country from Saturday through Monday as snow, ice and freezing temperatures disrupt operations at major airports. The extreme weather triggered emergency declarations in multiple states and forced airlines to ground flights, significantly affecting travel schedules and passenger plans. Authorities warned of dangerous cold and continued travel impacts as the storm moves through the eastern two-thirds of the U.S.
