So I just moved to Stockholm and I'm thinking if I should try and accrue more miles, specifically with credit cards, I am considering either sticking with MM, maybe get their credit card, as I have flown LH and LO a bit, or if it makes sense to invest in SAS eurobonus as their credit cards seem better.
