The CE of Delta Air Lines says the company will seek compensation for its losses after a power outage knocked out the Atlanta airport's power supply and also its backup electricity for about 11 hours Sunday. The blackout stranded thousands of passengers and led to the cancellation of more than 1,500 flights just ahead of the frenzied holiday travel period. Delta CE Ed Bastian said that he found it "shocking" that it took so long to get power restored. Bastian said he doesn't know whether Georgia Power or Hartsfield-Jackson Atlanta International Airport was responsible, but said Delta will have conversations with both. Bastian also noted that the airline may have lost US$25m to $50m of revenue as a result of the blackout. <br/>
