It was an American Airlines flight from Chicago to San Diego on a Thursday in June, seat 14C, 12:47 PM local time. I had boarded early. I was in an aisle seat on the right side of the plane. The woman across the aisle from me in seat 14D was a plus-size woman, mid-forties, kind-looking, already in her seat when I boarded. She was reading a paperback with a pink cover. The middle seat next to her — 14E — was empty. About halfway through boarding, a man in a charcoal suit, maybe fifty-five,

came up the aisle and stopped at our row. He looked at his boarding pass. He looked at the middle seat next to her. He looked at her. Then he looked at the boarding pass again. And he said, out loud, in a voice loud enough that at least six rows around us could hear: "Are you kidding me." He said it not as a question. He said it like a statement. The woman in 14D did not look up from her book. He said, again, louder: "I paid for a full seat. I am not sitting like that." The flight attendant was six rows away. He turned and walked to the flight attendant. I was already, in my head, dreading what was about to happen.
