I booked a ticket with both IB code and operated flight as well as IB code but AA operated flight.

I had no problem assigning seats on the IB coded and operated flight in advance as an EXP. In fact, the website allowed me to assign any seat I wanted, including exit rows, free of charge.

I was unable to assign seats on the IB coded but AA operated flight on iberia.com. I called EXP desk and they were unable to assign it either even though it's AA operated. EXP agent and her help desk explained that the computer was pulling up the flight as if it's operated by IB

I decided to call IB and asked if they could help. They agent initially told me to call AA since it's operated by AA After telling her it's IB coded and AA was unable to assign seats, the agent put me on hold to check. She came back and told me she could access to only a limited section of seat map (it sounded like non-elite section only) and was able to assigned me whatever seat I wanted that was not in the elite section, despite me being an Oneworld Emerald EXP. I checked expertflyer and saw the seat I chose as confirmed.

So, at least it is possible to assign seats, albeit non-elite, on AA metal even if you book it as IB coded.
