OSL > DXB = Business (R) = 60 Qpoints
DXB > DOH = First (A) = 100 points

I think that's how I see it, at least based on the fare classes as listed on my QR calculator and the Qpoints Calculator? Unsure if it's like BAEC where the DOH > DXB leg is so short that a First ticket gets treated as biz, especially given that it's a biz ticket marketed as First.

I've already found 2-3 different journeys to Asia I want to do this year and flying Ex-EU out of Oslo makes these all under $2000 RT in J. Definitely handy to get status, for example: OSL > DOH > BKK in Business Classic (R) is 120 Qpoints RT for under $2k. Seems like there are lots of sweet spots and MRs to be had.
