Delta CEO Apologizes for ‘Unacceptable’ Flight Disruptions

Delta Air Lines Inc.’s chief executive officer apologized to customers for an “unacceptable” level of canceled and delayed flights, an unusual step that reflects mounting frustration among waylaid summer travelers.

Delta is adding extra boarding time for flights, building in more of a buffer in crew schedules to mitigate disruptions and using white collar salaried workers to help speed customers through airports, Chief Executive Officer Ed Bastian said in a letter to its SkyMiles frequent flier program members Thursday.
