I thinks its indicative of AC's lack of a coherent brand strategy - they are just making it up as they go along. Another example is that Tango is supposedly a long haul destination carrier and yet flies YOW-YYZ.
AC's strategy is reactive in nature and driven by short term competitive issues - there is no long term plan apart from having lots of brands.
Discount fares on mainline AC earn status miles, but Tango (which may cost more for the same route) does not. Doesn't make much sense to me.
