Apologies for asking an AA specific question, but since I’m stuck in Dallas overnight: AMS-DFW was fine, but then they’d forgotten to put the aircon on and the aircraft was too hot to board. Put back in fifteen and twenty minute increments until weather rolled in (over three hours later).

My read is there isn’t a delay claim - but does the EU origin mean there is a duty of care? AA currently stonewalling everyone based on it being “weather”.
