A woman boarded this flight and had this story:
"I boarded a flight to Minneapolis, MN at 8:30 a.m. This man was in my seat, and I thought he might be inebriated. Once everyone boarded the plane I got in my assigned seat an realized his seat was next to mine. I breathed in deeply, but told myself that I wouldn’t be that person to treat him differently. The doors closed and, to my relief, he noticed that no one was in the seat on the aisle and moved over. I put my headphones in and got ready for take off. Throughout the flight, I could hear him making loud outbursts. Roughly 40 minutes before we landed, he laid across the two seats with his butt towards me. He continued his loud outbursts and began aggressively flipping the tray open and closed, then he sat up. I saw him take the cigarettes and lighter out of his pocket. I pulled out my phone and started to record as he lit the cigarette. The man across from us became nervous and flagged the attendant down as I recorded. The attendant put the cigarette out on the tray and took his boarding pass. He didn't have any other issues, and when we landed, the airport police took him off the flight first."
