There will be more upgrades soon.
I think they are trying to stay slightly fat on F/Os in case we have to ramp up for something. Not implying anything, but we all know they are trying for some more flying. If we got something and got behind the curve with pilots it would not be good.
I don't know much about the current attrition, but I did just talk to PP and he said they are currently upgrading about a half dozen per month.
Getting closer.....
