Delta Airlines DAL, -2.36% flights in the U.S. were grounded Sunday evening because of computer problems. International flights were not affected. The ground stop for all Delta-branded flights, as well as its regional partner carriers, meant that no flights were allowed to take off. It was the second such nationwide shutdown by Delta in the past six months. Last Sunday, United Airlines suffered a similar ground stop for about two hours after a computer glitch.
