Massimo Vignelli, the 81-year-old designer behind the 1967 "Silver Bird" design recently scrapped by American Airlines, is among those questioning the brand's logo change. "Clients without [a] sense of history could not understand the value of equity. ... It seems to me that there was no need for American Airlines to undertake such a change, but many people do not understand the difference between design and styling, and believe in change for the sake of change," he told CreativeReview. Calling the logo rollout "turbulent," writer Robert Klara says the lesson is a simple one: "If it ain't broke, don't fix it."
