AC.com says that I must rebook the entire flight, even if I'm only changing one leg. I see the discount is retained, but the price for the departing leg, which I do not intend to change, has doubled. I must click this before I am allowed to change the return leg. I'm ok paying the fare difference only for the return leg if the 30% discount is applied, ridiculous website is making me rebook the departing leg too.
Worried about calling in and whether they would make this worse for me.
Not sure why I need to rebook the departing leg.
To specify, the departing leg is in lowest business, YVR-LHR and the return is in PE (O) and fully refundable.
New total to effect this change is over 5 thousand as per ac website. I'm clearly missing something here.
