 Delta Airlines apologizing for thousands of canceled flights over the weekend following massive computer disruptions. It started Friday after a faulty software update from cybersecurity firm CrowdStrike caused millions of computers to crash around the world. For Delta, that translated into more than 3,500 canceled flights. Delta CEO Ed Bastian issued the apology yesterday, along with offering up frequent flyer miles to affected passengers, saying the airline understands how difficult it is to have your travels disrupted.
