I would assume that CR1s will be treated like SWUs on the CO side, which is to say just like mileage upgrades in the priority.
I am still a little confused with ZE and R, so apologies here. I know ZE is for Y/B/M-Ups and R is for pretty much everything else. So, before releasing R, CO will run EUA for ZE first to upgrade those on instant uprade fares?
With that logic, naturally I would assume that we will never see R inventory when ZE is zeroed out [but there can be as many ZEs and Rs, i.e. F5 ZE4 R4 and any upgrades will eat into both ZE and R, but never F5 ZE0 R4].
AS upgrades everything into U, hence my ignorance, so be patient with me
After a few roundtrips I should have a good understanding of how everything works
