Delta Air Lines Inc. suffered from system outage for two-and-a-half hours, leading to a huge monetary loss for the airline giant. The airline company had to deal with and compensate angry passengers whose flights had been delayed and/or canceled because of the technical issue.

On Monday, about 170 flights had been grounded when Delta Air Lines experienced a computer system breakdown. The company announced that it is anticipating that 80 more flights and counting had been canceled because of the outage, The Boston Globe reported.

Only flights within the United States were affected. International flights were business as usual. Despite the company's claim that its international flights were not affected by the outage, some customers are saying that their flights have been delayed as a result of it. There has been no confirmation whether the customers' claims are true.

The disruption in Delta Airlines' domestic operations was reportedly due to "automation issues," according to the Federal Aviation Administration. The announcement threw out speculations that hackers caused the outage.

CBS 4 Indy reported that Delta Airlines also experienced some significant IT issues in 2016 that led to angry passengers. The more recent issue also affected the airlines' website and mobile apps, which means that customers could not get in touch with the company online while the disruption was ongoing.

To appease angry passengers, Delta Air Lines will not charge its normal fee to change flights for customers who will travel Sunday and Monday. The airline also decided not to charge its customers for rebooking their flights by Friday.

Delta Air Lines CEO Ed Bastian has expressed his apology to passengers who were negatively impacted by the outage. However, he did not give any other details as to what exactly caused the outage.

Jobs & Hire previously reported that Delta Air Lines enjoyed steady demand for U.S. travel in 2016.
