BAs Comair is (albeit not IAG owned)
The LCCs Jetstar (QF), Jetstar Asia (QF), Jetstar Japan (QF/JL), Jetstar Pacific (QF), Vuelig (BA/IB) are not
Flights on MASwings used to earn miles but this is no longer the case when crediting to AA and BA. (And probably many other OW airlines)
From AA.com:
Flights operated by Firefly and MAS wings are excluded from all frequent flyer program terms.
MASwings is also no longer listed on oneworld.com
