I'm obviously not saying that there isn't any space difference. But I am arguing that as J gets better, demand for F goes down. I think fewer and fewer corporate customers, for example, would pay for F nowadays when you can get a solid night's sleep in a business class flat bed and arrived refreshed. That leaves F for (a) the few still willing to pay a premium over J and (b) business class customers incentivized to fly AA by a upgrade to F.
Given the economics on the plane — every single F seat replaces 2.5 J seats — I would be surprised if the demand for first class fares plus the demand for J fares that would otherwise book away from AA if not for the ability to upgrade to F is sufficient to justify the cabin.
