United Airlines, one of America’s ‘Big Three’ carriers, and more recently, achieving the title of world’s largest carrier by fleet size (surpassing 1,000 aircraft), flew with the slogan ‘Fly the Friendly Skies’; this was first introduced in 1965, with an approach to entice the public onboard with its warm, approachable, genuine attitude. However, as the carrier grew in popularity and slogans changed, the carrier brought it back to life, following several public relations nightmares.
