Delta Airlines says it is working around the clock to restore service to normal after yesterday's computer outage.

The disruptions Tuesday follow about 1,000 canceled flights Monday and, according to FlightStats, about 2,800 delayed flights, after an outage at Delta's Atlanta headquarters instigated a global meltdown of its booking and communications systems.

The airline was back online after a number of hours Monday, but the outages were so widespread that it is still dealing with the ripple effect a day later.

FlightStats, a flight tracking services, put delayed flights Tuesday at close to 600, and canceled flights closer to 330.

Delta also extended to Tuesday travel waivers issued to the stranded. In addition, it has offered refunds and $200 in travel vouchers to people whose flights were canceled or delayed at least three hours.
