There are some limited QF codeshares out of Asia, and priced the same as the EK code, particularly from SIN

eg. looking SIN-DXB-DUB return in November
Either QF codeshare or EK pricing as S$7566 as Business Saver


But from BKK no codeshare - although you can get codeshare at DXB to say FRA, LHR (albeit not to DUB

No codeshares offered at all from KUL, CMB etc.
which is a pain if after QF SCs
