Now that it's been flying much of the year and they've had a chance to iron some things out, has anyone recently had premium-cabin experience in the "Legend is Back" 321T transcons between California and New York Kennedy? Specifically, is F class worth the extra miles or fare over J class on the new bird? I know that F is 1-1 seating an J is 2-2, but both are flat-bed. I know that F gets you "Flagship Check-in" and the "Flagship Lounge," whereas J gets you "Priority AAccess" and "Admirals Club." I know that F even has a spot to stow a small dog, which I don't have But beyond that, how about food, wines, stAAff attention and service, etc? Is the difference worth it? And, if anyone knows, how does their F and J compare to DL's "Business Elite," UA's "Business First," VX First, and B6 "Mint?"
