United Airlines warns of delays after ground stop for ‘technology issue’
United Airlines passengers faced the prospect of delays Wednesday evening after the carrier requested a nationwide ground stop because of an apparent IT glitch.
“Due to a technology issue, we are holding United mainline flights at their departure airports,” United said in a statement to TPG. “We expect additional flight delays this evening as we work through this issue. Safety is our top priority, and we’ll work with our customers to get them to their destinations.”
The ground stop was requested around 8 p.m. EST. As of 9:40 p.m. EST, flight-tracking service FlightAware showed that a third of United’s mainline flights were running behind schedule, though that figure included flights from before the ground stop went into effect.
Delays – and possibly cancellations – were likely to further ripple across United’s network, especially if the ground stop drags on.
A “ground stop” holds flights on the ground so that arrivals don’t back up at an airport experiencing an issue like poor weather or another event that restricts arriving flights. In some cases, an airline will request a ground stop if it’s experiencing an operational issue, which appears to be the case for United this evening.
