"Please return your fiance to her original upright position."
Who thinks of this ####?
The pitch starts with a goal. They're trying to associate something with their brand, but they have to position their product in a way that the association is obvious and assumed, because people will believe what they infer more than what they're told.In this case, the product is a gift, so there are two markets - the giver and the receiver. The gift receiver, usually female, wants to believe that the gift is something she wants. The gift giver, usually male, wants to believe that his gift will lead to something he wants.
The gift receiver is led to believe that she's no longer in an upright position because she's been swept off her feet. A sympathetic female flight attendant emphasizes the romantic gesture and announces it for the whole plane to hear.
The gift giver is led to believe that she is no longer in an upright decision for a different reason. Why did she go down? Was she fully prone? She doesn't seem to be upset that they're in public, and that the attractive female flight attendant is watching.
So while the commercial is ridiculous, the message is clear - women, you have to wait for a man to give you expensive jewelry to be swept off your feet, and men, giving that jewelry will lead to sex. It's the same pitch that they've been using forever.
