Upgrade might have touched the most senior of the recalls but its still a rarity at this point. And I think its a misnomer to say they "bid what they can hold" since that usually means something else. Even new hires "bid what they can hold" but its only relative to what's available. AFAIK the recalls can only bid on whats available. Unlike a new hire they don't get a freeze, although freezes are waived for first upgrade anyway I think. But just to be clear recalls can't just pick any seat on the list they can hold and say they want that.
