Airplane conflict resolution

Social media is full of stories about people seeking to change seats and bullying fellow travelers who refuse to move from preselected premium seats. A fellow traveler insisted I was in his seat on a flight from Chicago to New York last summer. I was not in the wrong seat. It was the window seat he would have purchased had I not bought it first. He warned me he needed to spread out his entire office on his tray table, and he’d block me from getting up to use the bathroom. The joke was on him. Chicago to New York is no challenge for my bladder.
