DALLAS—Southwest Airlines posted its first quarterly loss in nearly a decade and said on April 28 that the downturn in air travel that began in late February shows no signs of letting up.

The airline said trip cancellations have pulled back from a peak in March but remain at levels that Southwest has never seen, as customers scrap plans to travel during the CCP virus pandemic.
