Unsupported ‘sickout’ claims take flight amid Southwest woes

DALLAS (AP) — When Southwest Airlines canceled more than 2,000 flights over the weekend, citing bad weather and air traffic control issues, unsupported claims blaming vaccine mandates began taking off.

Conservative politicians and pundits, including Republican Sen. Ted Cruz of Texas, alleged the flight disruptions resulted from pilots and air traffic controllers walking off their jobs or calling in sick to protest federal vaccination requirements.

The airline, its pilots’ union and the Federal Aviation Administration denied that.

“The weekend challenges were not a result of Southwest employee demonstrations,” Southwest spokesman Chris Mainz said Monday.

Still, Twitter posts claiming airline employees were “standing up to medical tyranny” and participating in a “mass sickout” amassed thousands of shares. Vague and anonymous messages on social media speculated that Southwest was hiding the real reason for its disruptions. And anti-vaccine rallying cries such as #DoNotComply, #NoVaccineMandate and #HoldTheLine were among the 10 most popular hashtags tweeted in connection to Southwest over the weekend, according to a report from media intelligence firm Zignal Labs.

Even as flights appeared to be running closer to normal on Tuesday, the Texas-based airline remained at the center of the latest front in the vaccine mandate culture war, its challenges exploited by opponents of vaccine requirements.

Neither the company nor its pilots' union has provided evidence to back up their explanations for why nearly 2,400 flights were canceled from Saturday through Monday. Southwest has only said that bad weather and air traffic control issues in Florida on Friday triggered cascading failures in which planes and pilots were trapped out of position for their next flight.
