Now, I understand all of their aircraft are converted and they're selling 3 cabins. If you buy main cabin you may clear to Premium, and waitlist to their J. If you buy premium if available you can clear to J via Z class. It was a remaining sweet spot to use GUCs but now the rules are the same for them and AF and DL. Question is if you want to spend Premium fare to confirm or just chance it. DL and their partners have successfully figured out how to lace the loyalty carrot with more required spending to fully realize the full benefit!
