No, the benefits don't extend to others on your reservation like they do with DL, I just learned this myself. In practice though, you should be fine with everything except seat selection & luggage, which you need to pay for.
I say this because she will be able to check in with you, go through security with you, use the lounge with you, board with you, etc.
Regarding luggage: as a DM you are entitled to Sky Team Elite Plus benefits (the same for GM/PM/DM). This provides 1 additional free checked bag over the allowance. On TATL flights this means you get two bags (as a coach pax) so you could each have one and you'd check both under your name. However, on inter-europe flights, you will only get one free bag (because the standard allowance is zero), and you'd need to pay for a second.
