We have recently moved to a ZL fare with UA and I was wondering if anyone could give me some advice while trying to get to MEL from the states. Looking through our agreement it doesn't indicate what fare class we purchase it, just the ZED fare class. That said, I am wondering what the likelihood of UA letting my partner and I go either F or C if Y is full? We are looking to go around the first few weeks in April but not sure if there is a DOW that is better than another? Is there a better chance to get out of SFO vs. LAX and vice versa?

A lot of questions, I know! We have gone through Europe fine on other airlines, I have just heard that UA can be tricky with other airline non revs. Thanks in advance for any guidance Let me know if I can be of any assistance with B6 questions
