Looks a perfectly valid xONE4 to me:
- 16 segments (the maximum allowed)
- valid number of flight segments within continents
- second entry to Europe/Middle East is OK (MLE-DOH-NBO)
- maximum of two stopovers in the continent of origin (DOH and LHR)
Fantastic!! Pandaperth- do you remember helping me out with my ex-MPM a few years ago? I was a disaster. I hope you are proud of your student's progress
AA will ticket, provided one of the "over water" flights is AA-marketed. So for you that means either HEL-LAX (AA codeshares on the AY flight) or LAX-HKG
OSL- xHEL-LAX-JFK-(DFW-LAX surface sector)-PVR-LAX-HKG-(DPS-SIN surface sector)-CMB-MLE-DOH-NBO-LHR-OSL
Okay- thank you! The only AA flight I saw for OSL-LAX is on BA and then AA, so I would incur more of those pesky fuel fines. But maybe not as much if it's short haul?
Do you particularly want to do a surface segment (DFW-LAX)If not, then it's OK to take two flights to get across the country, e.g. JFK-ORD-LAX.
I thought I could only land at LAX on my North America routing one time. And, the ORD stoppover would put me at 17 segments, right?

- I am a big fan of QR's long-haul business class- ME TOO
- I am not a fan of AY's business class (though I've only done short-haul)- Good to Know!
- I am not a fan of BA's business class (especially in its old 747s which it has on the NBO-LHR route)- Agreed
- I loathe BA's fuel fines (USD215 for NBO-LHR in business class)- TERRIBLE
- I am not a fan of Nairobi (I'm currently in Mombasa, been hanging out here since last November, loving it
and will likely head to ZNZ next where I lived for 5 months back in 2016)- Lucky! I wouldn't stay in NBO- I want to go to Tanzania and none of the One World carriers fly into DAR.
- I like to maximise mileage earning, and BIS miles in good business classes- Had to look up "BIS" Always learning

So, perhaps consider
(QR flies to
lots of places in Africa; JRO is close to a number of game parks and of course to Kilimanjaro itself)
We are planning on Africa for 2020, so that piece has to come last.
Happy travels.
Thank you! Keep the recommendations coming!
