Other than there being a fuss between the GA and three pax, there wasn't a "show" by any means. I was still blown away how anything like that could happen.
Me and my seat mate were on paid F and had the seats for weeks. I also remember looking at the seat map and not seeing any open seats anywhere either prior to boarding so who knows what caused the glitch. I think if I had already had a couple cups of coffee I could have asked more questions. I just didn't want to get booted myself.
