Perhaps this thread would be best in the OW forum as there is a pool of info on this topic and they do not necessarily check QF forum.

Questions,

What FF program(/s) are you putting the points into?
What class are you buying?

There are a couple of threads recently in the OW forum where the economy booking class for the OWE explorer is changing from M to L. I do not know if that applies to this product as well, however you will have to plan carefully that the booking class pays points, or full points, into your chosen FF account. For QF see the T&C's for exclusions and limitations.
