Right.
I get that. But most of us don't like paying an extra $708, which is the current difference between a T and a T+ fare on a YYC-HKG return fare on AC?
After all AC must make a profit.(which they infrequently do)

There is a balance, between charging more and frightening customers away, and currently AC is doing just that to many of the their FF who want T+ fares for full status miles and the chance to play aerolotto. AC is stretching their pricing "elasticity" to the limit.
It would be interesting to see the real numbers on the yields in Y( T vs T+) on those TPAC flights.
This is exactly why I worry that the days of the lowest economy fare giving full 100% status miles are truly numbered and soon we won't see this on ANY carrier.
