Delta Air Lines Inc. for the second straight year will fly American World War II veterans back to the beaches of Normandy, where they will receive a hero’s welcome from the French region they liberated nearly eight decades ago. Delta officials announced the return mission in the presence of “honored guest” Andy Negra, a Georgia veteran who plans to make the trip this year. He praised the Delta Veterans Business Resource Group, a group of veteran employees that volunteered to accompany the older World War II veterans throughout the trip last year.
