Bud Light's typical customer is a very different demographic than Delta's. We fly relatively wealthy people from one major city to another. High-income earners in urban locations (yes, even in the south) are generally more accepting of left-leaning political beliefs. And they are far less likely to follow right-wing fear-mongering twitter feeds or watch Fox News, so odds are most won't see that tweet. And if they do, they might be like me and not care enough to find out if it's even accurate or made up.
