On July 23rd, according to CNN, Delta Air Lines is still facing operational recovery issues due to global network failures. On the 22nd local time, Delta Air Lines cancelled over 1000 flights.
According to reports, American aviation data company OAG stated that from the 19th to the 21st local time, Delta Air Lines has cancelled over 4600 flights, more than any other airline.
Delta Air Lines CEO Ed Bastian apologized in a letter to passengers on the 21st, stating that it was due to a problem with the computer's "crew tracking" software.
The Associated Press reported that although other American airlines have largely returned to normal, Delta Air Lines is still struggling to restore normalcy. This further highlights Delta Air Lines' relatively weak response to this global technical malfunction event.
On the 21st, US Secretary of Transportation Pete Buttigieg stated that the department continues to receive reports and complaints about Delta Air Lines flight disruptions and unacceptable customer service conditions. He hopes that Delta Air Lines can provide accommodation and meals for delayed passengers, and quickly refund passengers who do not want to reschedule to later flights.
