I am looking at flying

DUB-LHR-EWR-MCO

DUB-LHR UA flight number but operated by Aer Lingus
LHR-EWR-MCO all UA flight number operated by United.

Can I use my UA frequent flyer number for the DUB-LHR and then my Turkish one for the remaining flights?

DUB-LHR won't earn me any miles on my TK account but will on my United one.
