An MH or QF flight number earns barely more than the flight distance, while an AY or JL flight number earns a nice multiplier of flight distance. Different starting points may enable different codeshare flights.
Add QR to JL and AY. With codeshares and the help of my trusty TA we were able to book even most US domestic flights on these 3 to make a trip that would have yielded close to 100 K LPs. (The snag is being ready to transit DOH twice. I'm in Singapore, and just happy to get to Oslo at this point.)
It's amazing that the whole scenario changes depending on which airline you're crediting to. AA didn't get my money this time, but they make up for it by being one of the high value airlines in someone else's program.
