Not to discredit your response (I agree that there is reason to question whether this is a publicity stunt or not, given his history of YouTube 'pranks' on planes), but Delta does have a history of being racist and Islamophobic towards their passengers. To name a few, when a Muslim couple were kicked off a flight for sweating and saying 'Allah', when a Sikh woman was forced to prove her breast pump wasn't a bomb, when they didn't believe a black woman was a doctor when another sick passenger needed help, and when a Muslim family was forced to move seats after being harassed by another passenger instead of forcing the harasser to move. I'm wary of people thinking that Delta airlines (or any other airline) is completely free of racism, just because this one person may have been pulling a prank this time.
