Yes thanks for your advice PABLOCO. I didn’t have to push too hard as that flight had a half empty J cabin. In any case the fare difference one way between PE and J was not significant, about the same as the compensation offer so I was well armed with arguments but didn’t need them...
What I still don’t understand is how an A320
can lose a PE cabin?? Isn’t it just a curtain and blocked middle seats and meal? not that I’m complaining at the overall outcome of course..
