Last last note: (unless I think of something else). At 70000 miles on Air Canada you also get a free companion ticket to anywhere Air Canada flies for any purchased ticket, any fare class (this is in addition to your 10000 bonus miles). I will reach this level easily by the year's end and it is a welcome bonus compared with the usual companion ticket on only full fare paid tickets. When you reach 250000 miles you get a choice of home entertainment system and other items of extreme value (if you do qualify, you are probably never home to enjoy them).
