Analysing those numbers it looks like most of the 747 Captains took the package, and about half the FOs (assuming the remainder of package takers were FOs).
About half of 380 Captains too, and about a third of FOs. That would mean that if the fleet is going to return by anything more than half then training slots will happen, and maybe even some promotions.
A quarter of 330 Captains and about a sixth of 787 Captains. If these fleets come back to full strength in a year or two, and if the extra 3 787s arrive, then there'll be some command slots required to fill them.
There is some light at the end of the tunnel suggesting room for promotional opportunities and command opportunities with those numbers when international flying returns.
Still a lot of the other ranks remaining, especially 4 engined second officers. A lack of front seat time will affect their opportunities for advancement.
