Monday, American Airlines will unveil its first major brand campaign since the successful integration of the legacy AA and US Airways. With the tagline "The world's greatest flyers fly American," the new advertising from AA's ad agency of record — Crispin Porter + Bogusky — memorably establishes and conveys a particular mind-set AA aims to instil in both employees and passengers. The result is a new campaign — at least in its initial phase — that is not about lie-flat seats or airport lounges or route systems. Rather this AA campaign is nothing less than a call to arms to all who work for — and fly on — American to renew their focus on what can make flying something more than the ordeal many have come to believe it too often is. <br/>
