Yes. He also said for short haul PE-J Silver RU (didnt say their own or whether gifted) trump Elite SHRU RU/EAPD from Y to J.
ie all the PE-J upgrades considered above the double class upgrades.
didnt say whether this was the case for long haul or not.
He seemed to have a list of the pecking order of upgrades tho wouldn't read it out unfortunately.
