No worries about the batteries, I think we're at the core of it. Your entire framework for assessing this incident devolves into an assessment whether the passenger had a contractual right to be there, despite policies stating he didn't, federal laws giving the airline personnel the authority to make that determination, and basic common sense that says that's the wrong way to contest a possible contract breach.Running out of battery so trying to be succinct. You don't get ruled to be being reasonable IF your actions are actively unlawfully breaching your contract.
I think we're done here.
