Struggling to see thai as an alternative to emirates. Sure no upgrade on emirates, but at least there are lounges and some level of status recognition. Seat selection is do-able. The other thing is that you can qantas on the long leg, with upgrade chance, and then emirates on the short leg to paris or madrid.
Would be interested to hear the reasons thai is considered an alternative. Does the OP have star status?
