United Airlines briefly grounded all flights after a technical glitch hit its computer system Wednesday morning, but the issue has since been resolved, the Federal Aviation Administration says.
The airline has a major hub in Chicago and services flights to a number of cities out of the Twin Cities, including Chicago, Denver, Washington D.C., New York and others. United also has service from Duluth to Chicago, and flights from Fargo, North Dakota, to Denver and Chicago.
The problem was reported shortly before 8 a.m. and caused issues for both United and its feeder airlines, such as United Express, CNN reports. By 8:20 a.m., the feeder airlines had been released from the ground stop.
Just before 9 a.m., the FAA canceled the ground stop for the remaining United flights.
Minneapolis-St. Paul International Airport spokesman Pat Hogan told FOX 9 that the glitch didn't appear to delay any flights in the Twin Cities.
However, at MSP and airports around the country, reports noted there were crowds of people waiting in long lines Wednesday morning. Some passengers also reported issues with downloading mobile boarding passes and checking baggage, reports note.
At Hector International Airport in Fargo, the issues caused at least one flight to be delayed for about an hour, with airport officials noting passengers could encounter some travel delays throughout the day as a result of the computer glitch, Forum News notes.
About 3,500 flights were affected during the system problems, NBC News says, and about 235 domestic and 138 international destinations are expected to experience delays throughout the day as a result of the glitch, especially at the airline's major hubs.
Some tweeted their frustration with the delays, while others made light of the situation.
