EK doesn't strike me as the alliance sort.
EK 2020's reminds me of SQ of the 90's - the airline that put it all in their hub location as connecting the world. Sure they had strategic partnerships (to their advantage.. remember SQ/DL?).. EK to me, overflowing with 77W/380's is all about DXB and having as many connections online EK through DXB to everywhere else. All that OTT shiny glitz everywhere
I mean it's not out of the possibility of course but I just can't see it.
EK seems to pick and choose its partners for its own benefit (eg: EK/AC, EK/UA, EK/QF) - all areas of countries that can provide some feed to/from EK but not going to be much direct competition on key routes where EK has capacity and product.
Certainly QR in OW has probably irritated EK somewhat but their operation at DXB is still pretty safe.
