Well, that's easy: Fly more often, and pay to sit in the front of the bus!

The earning rates for Qatar economy fares (apart from full-fare Y and B) on all other OW programs are dismal - no more than 50%, the cheapest ones earn only 25% or even nothing.
When you fly economy on QR and want some decent earning rates, sticking with QR's own program is the only viable choice.
