This guy will get a chunk of change from the airline because of the bad press, not because of what the airline did. If he deserves anything, it's from the airport who the security guys work for.
Psshhh..bitch please... the national populace will forget about this in a week. People only care because it went viral and the talking heads on TV got ahold of it for their weekly social justice rant. It's not because there is some national rage against airline quality. I like my $400 coast to coast flights and so does the rest of the nation. United will lawyer the fuck up and deflect damages on to security personnel.
People will cry about regulation changes and politicians will get ADHD and knee jerk react to the next overly melodramatic national outrage that has very little importance to our long term prosperity. United' stock will recover because it's a major airline powerhouse and has a huge market share and large revenue. Nobody really gives a shit and I hope this thread realizes that too.
