US airlines affected by winter storms, ongoing pandemic

US airlines operations were affected over the weekend due to winter weather and COVID-19 infections. The Federal Aviation Administration warned that it was facing its own staff shortages that could ground more flights. “The aviation workforce is essential to maintaining the operations of air travel and cargo supply chains,” Airlines for America said, praising the Dec. 27 decision by the Centers for Disease Control to shorten recommended isolation for mild cases from five to 10 days, a move A4A said, “is the right one based upon science.”
