Delta CEO Ed Bastian sent a letter to U.S. Attorney Merrick Garland asking that convicted unruly passengers be placed on a national no-fly list, a move that would prevent them traveling on commercial U.S. airlines. His request comes amid a surge in disruptions in the past two years. “Delta has put nearly 1,900 people on its own no-fly list for refusing to wear face coverings,” according to Business Insider. “The airline has also asked the Transportation Security Administration to seek civil penalties from 900 people banned from flying on Delta.”
