just got off the phone w/ SE tix agent re YVR-SYD-YVR:

tells me the only fare that allows change to return while away is BLXAP12.

In order to get the system to quote this, you need to specifically request, otherwise it generates BLWAP3: 14 DAY ADVANCE for any changes to return portion! Plus, pay the $150 for the privilege...

What? I recall flying H last year and being able to change return while in Oz...

I'm booking Low Season;

H = $1962 (no changes permitted)
BLWAP3 = $2182
BLXAP12 = $2357

The issue for me is that I always need to be able to change returns when overseas. Last year I bought primarily H to accomplish this (B on some routings). It appears that fare class "adjustments" are the equivalent of gouging the consumer, but before I rush to judgement I'd appreciate hearing the wisdom of the FT'ers.

Any hints/help on clarifying my understanding of this Air Canada arcana?
