United Airlines has grounded their entire worldwide fleet (except for regional jets in some locations) due to a technical glitch. According to this NBC News article:
United Airlines grounded all flights worldwide Wednesday morning after its computer system suffered a technical glitch, causing a ripple effect of heavy delays throughout major airports.
About 3,500 flights were being affected. The delays could reach 235 domestic and 138 international destinations.
“We experienced a network connectivity issue this morning,” United confirmed in a statement after 9 a.m. “We are working to resolve this and apologize to our customers for any inconvenience.”
The Federal Aviation Administration specifically blamed the ground stop on “automation issues.”
It’s not the first time United has had large technical glitches. Unfortunately, I don’t think it will be the last. If you’re traveling soon, plan accordingly for delays as most planes are full and this is likely to cause a bit of havoc. Thanks to Neil M. for sending this my way.
ETA: It appears as of 10:15am EDT the ground stop is starting to lift.
