Or maybe they'll just do what everybody else did when they got rid of F and turn it into more J seats. That's what DL, KL did with the 747s and what everybody has done with the single deck wide bodies when they dump F. They might also be thinking of converting the F cabin to a real PE as well. Just like UA has been doing and OZ is doing now with their 747s, I'm sure that they'll use the current F cabin, until they replace them, as a premium J or give it to the OZ elites with purchased J.
