The agent noticed it was a RTW trip when she saw the fare basis on the eticket paperwork and mentioned it had been some time since she had seen one. It appeared that she believed me when I said they were free changes, but had to go with what the rates desk told her.
I didn't pay since I knew the rules and it was changed back.

I'm changing one sector (the next one, PDX-LAX) to an earlier flight (AA6026 to AA6025) and the last US domestic (DTW-DFW) to a later flight (AA43 to AA301). Same dates, same carrier, same routes, just a time change.

It's with the travel agent back in AU now. They have it set up to change, but AA is making them wait until the last sector (DFW-PDX) is showing in the ticketing GDS as used.

The only flights on my trip that a simple time change would cause a "ticketed points" fee is changing the OSL-LHR-DFW to have 2 more hours in LHR then currently ticketed, causing a 22 hour connection to become a stop over.
