I wonder if they would do PE on the 78J...and if the 789 has lie flat J (i.e. non-regional configuration), kind of strange why there is no PE, right? I think PE demand can be easily controlled by pricing.

Otherwise, they can't really put them on routes with the 77W, right? It almost seems to me they should have done 2 configurations of the 789 - one regional and one long haul.
