Hello all. New UA Gold member (matched from AA) and trying to figure out both UA and *A. Forgive me if there's an obvious answer to this question, but I've been searching for a little while now and I can't find it:
If I book an award flight with 2 stops on a *A partner, but later availability for a 1-stop flight on UA pops up, is there a change fee and, if so, what is it? I'm trying to plan a trip to South America in December and while I'm finding Business Saver availability from TYS-EWR-YYZ-SCL on AC, I'd prefer to go TYS-IAH-SCL on UA. So I'd like to nab the AC flights while I can but still be able to change to UA if it becomes available.
