However, throwing the codeshare into it, I don't have any idea if that changes things. I've only ever inquired about it with it being a codeshare.
The codeshare thing is annoying. I'd rather not have to book it and just book straight OZ. OZ has some decent refundable D and Z fares that price out close to what UA prices out in full Y.
I'm not sure whether I could just have OZ upfare it, or whether I'd have to deal with US to deal with it.
