I wonder if anyone anyone was ever successful at getting a detailed breakdown of taxes and fees of a xONEx originally booked, ticketed by AA and eventually re-priced and re-issued by AA. If so, I'd be curious to know about the process and the AA department that provided such detailed breakdown.

I am asking because after I made routing changes to an existing xONEx with RTW AA Desk, the re-priced/re-issued ticket does not provide a detailed breakdown of taxes/fees under my personal AA online account. I have asked the AA RTW Desk to provide the details, but they said they don't have a way to access them and suggested to contact AA Customer Support. I was expecting a larger refund of taxes/fees based on the changes I made, but not having a detailed breakdown makes it impossible to understand what happened to the recalculation of taxes/fees.
