Delta sends consumers on guilt trips

What's more powerful than a guilt trip to influence someone to do something? A guilt trip from a Mom.

Delta used this force to raise awareness of its growing presence in Seattle, a city that is made up of 60% transplanted residents, with an outdoor campaign that features handwritten letters from Moms to their adult children living in the city, guilting encouraging them to come home for a visit, complete with pictures and all. While this ads a nice personal touch to the campaign, we assume Delta received approvals from all parties involved before launching the campaign, otherwise they could have some unhappy people for being Mom-shamed in public.
