<p>Only once I had a person refusing to trade his window seat in coach for my first class window seat. He sounded really strange and a bit jerk-ish, so I asked the dude on the isle side of MrB, and it took him a nanosecond to jump up from that seat and run to the first class cabin. Turns out, the window guy was simply very nervous, because he was waiting for his dog crate to be loaded into the plane, and it was his dog’s first flight! Lol. He should have just said that.</p>
