I think you need 60,000 miles for YVR-ARN RT in economy class unless you take direct flight (apperantly not possible with their partner(s)). The calculation of miles is not based on point-to-point like onewold award in AAdvantage (still so?). I have to say their definition is a little ambiguous, but they certainly calculated the total miles for all the flights when I requested the award ticket (it was AA & CX combination award).
