Has anyone flown with SAS Ireland yet. If so, is it scandinavian flight crew and/or cabin crew or UK/Irish crew operating the flight?

Noticed EI-SIA and EI-SIB operated the majority of flights between CPH-LHR. One thing that surprises me is, that SK501 is operated by SAS Ireland. Why do they have overnight stops in CPH? I though the idea was to have base outside Scandinavia.

What is also interesting is, that SK2795/2796 on 29DEC CPH-NCE was operated by EI-SIB. That is the only segment an SAS Ireland has yet flown not being btw CPH-LHR. Wondering if that was then operated by SAS "normal" crew or also SAS Ireland crew... Having a reduced flight program between Christmas and New Year, it should not be impossible to find a OY/LN/SE aircraft to operate on that day...
