United is promoting their copious legroom by suggesting they can accommodate a giraffe. But of course, giraffes (as show in their image) are known for their long necks, not legs. Sure, they have long legs, too, but that’s the primary association. They have big toes, don’t they? Dr. Scholl’s us not going to use them in advertising (unless they come out with a new NECK powder). Giraffe :: Neck.
An opportunity for a clear message but instead it’s an obscure message.
