Can I ask if anyone is having success with latitude fares ex-EU/UK to Canada being upgraded with eups? How long out are people getting them? I'm looking to fly in Oct and would like to fly AC but at the moment I'm booking BA largely because of this.

On a side note, I had a domestic flight recently (YYC-YUL-YHZ) eup come through, with the YUL-YHZ sector clearing a few weeks out, but the YYC-YUL sector only clearing at the gate. I appreciate this aren't long haul sectors but still a data point.
