Have people had success bidding for upgrades? Any tips?

I booked a flight to Spain from PDX. I booked through Iberia but it’s being operated by British airways. I want to upgrade to premium economy but when I called British airways to do so, they told me to call Iberia. Iberia then told me they can’t do anything till 24 hours before or I can upgrade when I get to the airport. I really don’t want to do that, and just want to buy the upgrade now. Has anyone had this issue or have any advice?
