Is there any way to upgrade one segment from Y to PY in a multi-segment AC only ticket?
Ie. AC102 YVR-YYZ is B788 this November/December, but I'm flying YVR-YYZ-YOW r/t. Fare difference between Flex (G) and Premium (N) for AC102 o/w is about $100, which I'm willing to pay. But I get no PY options for YVR-YOW on AC.com. Can I change the booking class for the one segment via an agent?
