A historic winter storm has tangled holiday travel and brought dangerous conditions to a big chunk of the United States, but no airline has struggled more to navigate the Christmas holiday rush than Southwest Airlines.

Southwest canceled more than 2,900 flights Monday — at least 70% of its schedule for the day — and more than 2,500 flights Tuesday as of 9:10 a.m. ET — at least 60% of its schedule, according to flight tracker FlightAware. The disruptions add to chaos that has left people stranded at airports across the country, many of them with little idea of when they can get home or where their bags are.
