Hope I didn't miss this and this has already been answered but:

On credit for *A flights:

I have upcoming US flights tagged with "Continental" rather then UA and my old CO OP # (which is now also my new UA # so seems safe to assume it will all work ok for credit also)

Will the merged system pick the credit up for these since they're tagged in US system as CO? Should I call, or have GA's, manually remove the CO and reenter as UA with my same OP#?

Wish I could change it myself by managing my future reservations on US website but there doesn't seem to be any way to do that.

I did fly last night on US with CO tagged and it did pick it up as *G like always but I'm curious if the *A credits will come through the integrated system?
