You are thinking of traveling to Houston from LA just to see what its like to fly on a WET DREAMLINER? Here is my take on it. It all looks the same on the inside. I get the feeling the material in there is very very flimsy and light, to save weight like all airplanes try to be light. The lavaratory doors feel like you break them easily with a shove. The overhead binned latches look flimsy and I can see maintenance nightmares on those. The seating looks all the same to me, maybe a little more modern look, and cleaner since its new, like driving a new car. I don't see the enthusiasm on this particular airplane. I personally think its over engineered. Then again, its kind of early to really tell.
I haven't flown in the plane itself, but I wouldn't make a special flight on it just to see what its like.
