Unfortunately, UA refuses to change the codes when I tried to do this. They insist that I only "paid" for the business class (on the second segment), even though I used first class miles for the entire trip. They said that if OZ changes the equipment, I would still have to pay for the upgrade in service. Very disappointing/illogical.
