Same for me. I'll be flying Copa for the first time this Friday, and I just submitted a bid.

The little meter graphic's arrow pointed toward "good" for my bid amount ($250USD), but I'm willing to increase it if the general success experienced here has been higher amounts.

FWIW, the seat map on my flight is showing half availability (8 filled, 8 open) on a 738, five days out.... but I realize that those aren't always accurate depictions of loads.

These upgrades go toward Z inventory, as per the phone rep.
Anyone know a way to see how much is available on individual flights, with CM?
