NEW YORK (NBC News) – United Airlines flights are no longer grounded 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.”
The ground stop, however, was lifted around 9:20 a.m. for United’s regional carriers, which can perform their own weight and balance checks.
Passengers at airports from Albuquerque, New Mexico, to Washington, D.C., to Florida complained of system backups and long lines.
NBC Connecticut said United passengers without a hard copy of their boarding pass were not being allowed to check in at Bradley International Airport in Windsor Locks, north of Hartford.
