Yesterday I used 5 RUCs each way from BUF-ATL (OL) roundtrip. I also used 1 GUC each way for domestic D1 ATL-OGG-ATL (OK). All flights are based on Z inventory. All tickets have been reissued and RUC/GUC closed. Here is the very odd thing, the Z class inventory on ALL flights concerned in EF is unchanged. So by deductive reasoning, Z impacts Upgrade inventory but Upgrade Inventory doesn't "necessarily" impact Z?
Was it Z9? I thought that 9 was as high as it displays but not necessarily the number of seats available (i.e. 14 seats avail for Z will still show as Z9).
