I'm planning my first AONE4, and I think it's ready for vetting by the experts here. My primary goal is to visit Australia, New Zealand, Rome, and Prague, but I also have some secondary goals:

- Find out what F is like. AA J is the limit of my meager experience.
- Sample some airlines other than AA (CX and BA in particular).
- Fly on a 747 for the first time.
- Accumulate AAdvantage miles.
- EXP (this trip combined with my normal business travel should do it).

I've been lurking here for a while now, and I've studied the FAQ and the various timetables. I think I have a pretty good grasp of the rules and have devised what I believe to be a valid itinerary (asterisks denote stopovers):

DFW-SFO*-HKG*-NRT*-HKG-SIN-HKG-SYD*-CHC*-BNE*-PER*-MEL*-LHR//MAD-FCO*-HEL-PRG*-LHR-YVR-JFK*-DFW

That surface segment between LHR and MAD is more of an intermission. I'm planning to return home from LHR on a separate ticket, and I'll be traveling to MAD for work soon after. Once my work is complete, I'll finish the remainder of my AONE4.

Now that I think about it, that trip from DFW to MAD will likely entail the return leg of my LHR-DFW ticket combined with an LHR-MAD-LHR round-trip. Might as well just resume the AONE4 from LHR.

A few questions:

- I added SIN as a mileage run; any compelling reason to stop there?

- QF or BA from MEL to LHR?

- Any suggestions for a twentieth segment? The only thing I've come up with is changing the first segment to DFW-ORD-SFO. Pretty much everything else I tried breaks a rule or would require me to buy a fifth segment in Asia, Europe, or SWP.

- What do I do once I'm ready to book this? Just call up AA and ask for the xONEx gurus?

Any other suggestions/improvements are certainly welcome.
