Having to scratch the visit to Australia I had on my RTW. Getting mixed information after an almost two-hour call with the AA desk.

I've flown CAI-DOH(connection)-FRA-MAD-MEX-JFK-LAX-ANC-DFW and still have left (as part of the original ticket) DFW-HND-SIN-HKG-ICN-SYD-PER-LHR-DOH.

I'm looking to switch to DFW-JFK-HND-SIN-TYO(connection)-HKG-HEL(connection)-DOH-DXB...and the agent was pretty incredulous that it would be possible. I think I'm within the rules and in fact, I'm downgrading from a DONE4 to a DONE3.

He did raise a point I'm not sure about, though. Said DOH-DXB (flight 16) would exceed my four-segment limit in Europe/ME? Is that correct?

And if so, would ending the RTW with HEL-DOH or HEL-DXB take care of that issue?
