All United flights are grounded right now
“Automation issues” have grounded literally every United aircraft this morning, and the FAA’s Air Traffic Control System Command Center currently doesn’t expect the ground stop to lift until 10:15AM Eastern Time at the earliest. “Automation issues” is another way of saying that United is having trouble with the back-end software and hardware that it uses to coordinate flights at the several hundred airports it serves. The FAA reports that the current grounding affects “mainline” aircraft only, meaning that United partners — the companies that operate regional United Express aircraft — may not be affected.
This isn’t the first time a software glitch has grounded United aircraft: an issue in early June resulted in a ground stop lasting roughly 30 minutes, but this one is running longer. We’ll keep you posted.
