I have a UA flight from SFO-LAS in a few weeks that is a Air NZ codeshare on NZ 086 ticket stock. I'm familiar with the SDC rules on UA issued tickets and have changed these a few times in the past as *G, but I'm wondering if anybody has any recent experience of whether UA will change a ticket that's not on UA ticket stock?
I'm pretty sure a few years ago that I changed a NZ issued ticket at the airport and the Premier Access agent was happy to do this. Is anybody aware of whether this is something they will still do even though it's not in the rules?
