thank you all for very interesting and informative discussions over my OTW, I definitely learned quite a bit for potentially maximizing the benefits from this trip and (hopefully) a lot more in the future.

I'm currently leaning towards QR program: as dvs7310 calculated, I'm going to have 82000 Avios and OWS. I should be to find 2 more segments marketed(or operated?) by QR within 12-month period. I will also call QF to see if it's possible to switch that AY marketed HEL-JFK trip to AA. Or there is some other way to do it?

I guess my follow up question would be why AA or IB program would be attractive for my case if they are both revenue based. IB will give me OWS but only less than 20000 Avios, AA will get me OWR and 20k miles unless I have some segments got distance award. Agreed that orphan program(I laughed when I saw this term) is no good and AA program has better redeem ratio, less surcharge and possibly better availability; but 4 times more points in Avios could offset the disadvantages?

This is actually fun, I almost cannot wait to book my next OTW ticket despite I haven't started this one!
