I was just replying to marcopizzaiuolo. Like all the other contributors on here neither they nor I know exactly what went on.
It will probably all come out eventually. Maybe Mr Banner was wronged but we do at least have an eye witness account of him throwing his BA card at an FA’s face. If true, and this came from the parents of an FTer on that flight, then he should have been offloaded.
I await the full facts.
