Maybe, but the big factor in the rapid availability of upgrade at UA was the really cr@ppy reserve rules to the point that nobody was taking NB upgrades, particularly the commuters and at LAX, SFO, and EWR. Provisions in the 2023 UPA that took effect in the summer of 2024 massively IMPROVED that, to the point that senior people are now bidding reserve and the reluctance of NB FO Commuters to upgrade has largely vanished.
