Thrifty Traveler: "The U.S. Department of Transportation is launching an investigation into Delta Air Lines, Secretary Pete Buttigieg announced Tuesday, the fifth day of the airline's ongoing meltdown that has canceled more than 5,000 flights and counting since Friday."
"What started with a worldwide software outage late last week that affected many major airlines has snowballed into an operational disaster for Delta – and Delta alone. As other airlines resumed flying smoothly this week, Delta scrapped more than 1,000 flights on Sunday and again Monday. By sunrise, the Atlanta-based airline had already canceled more than 400 flights scheduled for Tuesday."
