Call for boycott.
Similar to the situation with General Mills, my take is that if Delta Airlines wants to promote policies that hurt White Americans, then White Americans should boycott Delta Airlines. Let them earn their profits off the "Latinos" they so obviously prefer.
This all should tell White Americans the contempt corporate America has for them. Usually, you'd think that businesses wouldn't take the chance of offending customers. But when it comes to hating Whitey, politics trump profits. Further, they believe - with justification - that Whites will take abuse unlimited and that there actually will not be any harm to profits.
A thought experiment: if a major corporation openly stated that they support the total extermination of Whites, would that cost that business any White customers? It's doubtful.
