Once you are 99% sure that Iberia SHOULD be able to access the award space (because other partners can) then you can keep calling Iberia Plus (Hang Up and Call Again we call it...) until you find that elusive agent willing and able to book partner rewards.
Any doubt and the response will usually be some version of "can't find the award space" or "you can't book Avianca using Avios" because the vast majority of callers will simply accept that excuse.
