right...in those days you can fly CX and earn miles with AC Aeroplan - before Dec 20, 1998 (F, C, Y and even discount economy), CP Canadian Plus - on and after Dec 20, 1998, Passages (only F and C), and some other programs too (e.g. AA)...but mostly only for F and C travel...
but, the "bonus kms" that Celestar340 was talking about (1600 km for 6 sectors, and occasional bonus kms on certain flights)...only applied to the status miles you earn towards qualification with The Marco Polo Club, and did not apply to the actual miles you earn with partner frequent flyer programs...i.e. those bonuses gave you faster qualification towards higher status, but did not help in getting you faster towards free travel...
