I flew a roundtrip fare from YYZ-AUH via DUB with YYZ-DUB operated by Aer Lingus and DUB-AUH by Etihad. The ticket was sold by Aer Lingus and the boarding passes for the Etihad flights show sold as EI8042/EI8045. The YYZ-DUB and DUB-YYZ flights were credited to BA Avios and the Avios were credited at 250% (J). With respect to the DUB-AUH-DUB flights, would I credit those to Avios since they were sold by EI and have EI flight numbers or since they wereoperated by Etihad and their flights are able to be credited to AC, should I be requesting the missing miles from AC?

TIA
