Keep Climbing Campaign In America, there’s a huge gap between the way air travel is portrayed in ads (luxurious, with personalized comfort) and its reality (long lines, constant delays and rude service). This campaign uses the truth about flying as a jumping off point to express Delta’s commitment to making it better. “HUMAN FACTOR” “Human Factor” juxtaposes studies of aircraft and of Delta employees to express the belief that a better airline isn’t just about planes (they’re all the same, anyway), but about people. Dedication and service make a much bigger impact than 500 tons of metal and a paint job.
