American Airlines, JetBlue and Alaska Airlines have joined United Airlines in mandating that employees must be vaccinated against COVID-19, per the Wall Street Journal.

Why it matters: The Biden administration has been pressing businesses to require workers to be vaccinated against the virus as vaccination rates flatten across the U.S.

The big picture: American Airlines told staff on Friday that it would require all employees based in the U.S. and "certain international crew members" to be vaccinated, per a memo obtained by Reuters.

  • The American memo gave no timeline. But JetBlue Airways and Alaska Airlines said Friday they'd implement a vaccine mandate as early as Dec. 8, AP notes. That's the deadline the White House has given for federal contractors to be inoculated, with limited exceptions.
  • Delta said it's "still evaluating Biden's order," according to AP.

Flight attendants for an American Airlines subsidiary with a base in Philadelphia voted to authorize a strike Thursday.

Driving the news: Members of the union representing flight attendants for American Eagle carrier Piedmont Airlines picketed outside Philadelphia Airport (PHL) following the vote, according to the Association of Flight Attendants-CWA.

Why it matters: AFA's strike strategy "could affect the entire system or a single flight," the union said in a news release.

  • "Even the disruption of a few flights could threaten operations across the American Airlines Group system," AFA said.

Catch up quick: Roughly two dozen news outlets had agreed to hold stories based on leaked materials from Facebook whistleblower Frances Haugen for Monday publication — but the embargo fell apart Friday night as participating newsrooms posted a batch of articles ahead of the weekend.
