I'm not totally following. It seems you wanted to change the outbound, which does trigger a repricing of the entire ticket. Meanwhile, changing the return from BDL to ABC would also result in a refaring on the return (from AKL-BDL to AKL-ABC) and might possibly affect the whole ticket as now you're in a roundtrip instead of two one ways. These are not "small" changes in the grand scheme of things. However, the price you were seeing on AA.com for the new itinerary was lower than what the agents were quoting you? Also, where were you seeing O available? On just the segment in question or on ABC-AKL?
