My dislike for single aisle aircraft isn't about cabin pressure or the "impression of a wider open space". It's about the fact that it is ACTUALLY cramped, and the _one_ aisle will be blocked for most of the flight.

In a typical single aisle airplane, sitting in coach, you're expected to use the restroom "in your cabin" which is at the rear. If you're sitting anywhere _except_ the rear, your access to the restroom will be blocked for a significant portion of shorter flights by food/bev carts.

By contrast, on a widebody, there are restrooms front and rear. If your access to one is blocked, you can go the other way, and you can _also_ use the front or rear to access the _other_ aisle. It's the difference between feeling totally confined versus freedom to move about (other than having to hassle any passengers between yourself and the aisle).

I admit, with limited cabin service in economy, on a longer flight, the blocked aisle isn't such an issue -- but on the typical 1.5-3h narrowbody flight, the food/bev service does seem to be a significant obstruction.

I'm someone who would happily pay up for a lie-flat more frequently if it was priced at 2-3x a regular ticket rather than 5x+. Airlines are slowly expanding premium cabins, and I'd be hopeful that narrowbodies like this permit further growth, but the demand seems to be increasing faster than the supply, so the prices are still crazy.
