I have an observation and a couple questions that have come up as I try to set up my fourth xONEx. I have purchased a one way ticket to NRT for March 5, so I'd better get with it.

1. It's harder to originate in Asia than Europe if you're a US resident repositioning for value and preservation of ability to have several separate vacations utilizing the 6 NA segments. I will be originating in Tokyo and I hadn't realized how few cities have oneworld non-stops to US from cities not in Japan (which you can't transit until end of trip), And since I want to ticket with the American RTW desk (good service, familiarity, and the airline with which I hold OW emerald status), I will need a trans-ocean flight on AA metal.

2. Have any of you constructed a trip with emphasis on racking up miles and points? I'm planning on a DONE4 and was going to fly to Australia, then home. Easy peasy. Unfortunately, crises at work have curtailed the time I have available at the beginning of my trip--I'll have only about 2 weeks, but they'd be eternally grateful if I didn't take even that long. I'm thinking NRT-CMB-PVG-DFW, and saving Australia and Asia stops for end of trip. If anyone has tackled this problem, I'd love to hear your thoughts.

3. Is cabin bonus paid on the operating or marketing (ticketing) airline? Flying Sri Lankan to and from CMB means no cabin bonus on D fare. From NRT there is a JAL codeshare on that flight. Would I earn the 150% cabin bonus if I ticket with JAL flight number? JAL codeshare is not available CMB-PVG. I could go on CX CMB-HKG-USA, but CX pays only 25% cabin bonus on D so shorter distance might minimize value. With the 150% bonus, and lack of time to really savor the trip, may be it would be best to just fly first flight straight back on JAL after a few days in Tokyo.

In Oneworld ff earning are based on the marketing carrier. Is more complicated with revenue based frequent flyer programs.

Operating, marketing(flight number) & ticketing airline can be 3 different airlines. Marketing and ticketing are not the same. In your case ticketing airline will be AA (001 ticket). Could have a JAL marketed(flight number) with UL Sri Lankan operated (codeshare)

I called the AA RTW desk the other day. I had a chat about booking out of TYO and havin a trans ocean on AA. She said this is not absolute but sometimes enforced.and as an EXP they may make an exception. I am also looking at DONEX out of TYO. The only thing about originating in TYO you miss out on a lot of the Asian +3K segments . Still you can get a DONE4 to yield 210K LPs fairly easy.

You are right about +3K segments ex-TYO. If JL would fly non-stop TYO-BOM, that would be over 4K.

It hope it is easy to attain 210K LP on AA. Care to share some insights? TIA.

If you are an AA EXP, stay on Jl and QR when possible and AS in the USA. This is a example 210K+ DONE4 from TYO using no code shares.

HND-JFK-ANC-LAX-LIR-LAX-SJO-LAX-DOH-CMN-DOH-DUB-DOH-AKL-HKG-BLR-NRT

Good to know. I did put in an AA segment, DFW-DUB instead of direct DFW-DOH, but might try it given my relative time constraints.

Great information here, thanks,

I'm saving the above itinerary!
I've set up my DONE4 and found the flights, just need to call and get it priced, or corrected:
HND-JFK-DFW-ICT-DCA-ICT-DFW-DUB-DOH-AGP-DOH-AKL-MEL-CNS-AYQ-SYD-HND
As mentioned in original post, I decided to fly directly home from Tokyo on March 10, and will be going to see the cherry blossoms in D.C. instead of Tokyo in April. Then I'll head out again in November to take advantage of better weather in New Zealand and Australia. I think it will be worth about 145000 LP/RDM if I've calculated correctly (and I've ignored any class of service bonus on flights other than JL and QR). I will likely have some other flying over the summer, and I expect 65K LP from Barclay CC, so should requalify for EXP one more year. Maybe I should consider purchasing another to get home from Tokyo; they've gone up considerably since I first started planning several months ago. Trying to time the market though, could be tricky
As usual, thank you, I am grateful for the advice.

You 100% sure the DOH-DUB is permitted? I feel like you have one DOH too many there after one is arriving (LAX-DOH) and the other one is departing (DOH-AKL)

I don't think there's a limit on how often you can transit a city but you can only fly one RT between two cities. For example if you fly AUS-DFW-ORD-DFW- AUS, you can't fly AUS-DFW or DFW-ORD either way again.

I had to change my above itinerary, and it's now out for pricing. Ayers Rock just wasn't going to work. Later found out it might have, but I like the new one just as well: hnd-jfk-dfw-ict-dca-ict-dfw-dub-doh-agp-hel-doh-akl-mel-cns-syd-hnd. 45396 actual flown miles according to GCM.
After taking out AYO I had a segment to add somewhere and picked Europe. There was only one segment available so I couldn't connect through DOH again. AGP-HEL-DOH is not on QR (too bad), but it is on AY, another 150% D fare bonus!
The reason they couldn't find availability from AYO-SYD came to light when the agent was told we were up against the 331 day out reservation limit. Although she saw it all as available when I was giving her my flights, when she tried to book it they finally, after about 20 minutes, realized the problem. So I have to call back Jan 20 to fix the dummy dates for my last two flights.

Thank you for the data point. Appreciate it.
