People were saying the same thing about Pepsi the last few days for their stupid commercial until United Airlines knocked them out of the news.
Trust me on this: something will come along and knock United Airlines out of the news and this will all blow over. The average American is too stupid and has too short of an attention span for this to really affect United.
Not for me, it won't blow over. United sucks, and I will boycott them. They're pretty bad on service and overbooking, and that's it for me. No more United flying.
