Southwest Airlines canceled thousands of flights on Tuesday and Wednesday, as the company struggled to recover from a deadly winter storm that has left holiday travelers stranded around the country. © Taylor Glascock for The New York Times Customers at Midway contended with delays and cancellations at a Southwest Airlines counter on Tuesday.
