Delta Air Lines will provide $200 in travel vouchers to all customers who experienced a delay of greater than three hours or a cancelled flight as a result of the systemwide outage.

The vouchers are available for travel on all Delta and Delta Connection-operated flights.

"We know that travelers value our commitment to excellent operational performance, and today we did not deliver on that commitment," said Gil West, Delta's Senior Executive Vice President and Chief Operating Officer. "We want our customers to know we are thoroughly investigating the matter and that we are truly sorry."      

Delta cancelled hundreds of flights and hundreds more were delayed as it worked to reset its operation following a loss of power in Atlanta that impacted Delta computer systems and operations worldwide. Systems are fully operational and flights resumed hours ago but delays and cancellations remain as recovery efforts continue.

Customers impacted by the outage and who have provided their email address will be contacted today and will receive their voucher in 7-10 business days. Customers who have not been contacted can complete a Customer Care form on www.delta.com/wecare to receive their voucher. All travel must be booked by Aug. 8, 2017.
