While the debate over immigration and a border wall between the United States and Mexico has helped grind the U.S. federal government to a halt, Mexico's national airline, AeroMexico, is trolling Americans with a new ad called "DNA Discounts."

The ad features purported residents of Wharton, Texas, a town about 60 miles southwest of Houston, professing a variety of opinions about Mexico and its citizens. The ad also drops some knowledge about the long history of immigration from Mexico to the U.S., and notes that many in southern and southwestern states have a touch of Mexican DNA.

Things get flipped when the airline reveals it's offering flight discounts to Americans, including those Wharton residents, based on the amount of Mexican DNA they have (i.e., 18 percent DNA equals an 18 percent discount). That certainly turns opinions around. As one recipient says, "I love discounts!"

Of course, it's such a brilliant ad, it's hard to tell if those Wharton residents are real or just actors and if this whole DNA discount thing is real or satirical. Aeromexico, which has gotten political before, isn't saying much, but we've reached out for comment and will update this post when we hear back.

Either way, it's a brilliant gambit that undermines the vitriol so many Americans have expressed at our neighbors to the south, and does so without ever directly mentioning the political turmoil, the wall, or even President Trump. Instead, it directs that energy at a sense of shared community, including the tagline, "There are no borders within us." Not a bad way to spread a powerful message.
