The "Blue Flu" as it's being called because of the TSA's blue shirts, is believed to be caused by the ongoing government shutdown, which has stopped paychecks for TSA employees.

Economists at S&P Global said the shutdown has cost the US economy $3.6 billion so far. A Federal Reserve survey in May found that 40 percent of Americans would have to borrow or sell something to make a $400 emergency payment.
This is the longest government shutdown in history and has gone on for three weeks.
Friday marks the first day screeners will miss a paycheck, and airport spokesman Greg Chin said there's a concern there won't be enough workers to handle all 11 checkpoints during normal hours over the weekend. On Thursday, 99.9 percent of passengers waited less than 30 minutes, Bilello said.
US airport security workers and air traffic controllers working without pay have been warning that security and safety could be compromised if the government shutdown continues, but the Trump administration said on Wednesday that staffing is adequate and travelers have not faced unusual delays. "We thank TSA officers for their resilience and diligence, and we thank industry and the public for their continued acts of kindness and support".
