A computer systems outage at Delta Air Lines on Sunday night resulted in 150 domestic flights canceled across the country and numerous delayed and canceled flights at Minneapolis-St. Paul International Airport.

The computer problem was solved around 11 p.m. and flights began departing again, Delta said on social media, but more than 25 flight delays throughout the evening left some travelers at MSP grounded for hours. Other flights were canceled entirely.

The MSP website showed five flights were canceled as of 11:30 p.m. and three were still delayed.

Several stranded travelers said Delta gave them little information in the midst of the outage. The company issued a news release about 8:45 p.m. that said it is “expeditiously working to fix a systems outage that has resulted in departure delays” but gave no indication of how long the problem was expected to last.

“Airlines are very dependent on their computer reservation systems,” MSP spokesman Patrick Hogan said.

Stephen Swift was stuck at MSP with a team of 18-year-old volleyball players, including his daughter, from Atlanta. They all arrived at the airport at 4:30 p.m. in anticipation of boarding a 7:45 p.m. flight.

Delta canceled more than 2,000 flights over three days after a computer breakdown last August, according to Associated Press reports.
