Totally shocked by this. UA are off my list of airlines to use, oh, and so is the one that West Coast works for. I bet there are a fair few who were on that flight that will think again before booking UA (or co-carriers) let alone those globally seeing this thuggery.
A fare paying passenger treated in that manner just because Ops screwed up and his name was selected in a manner more suited to dystopian world selecting who will survive or not.
