Rebooking with AC discount code
I used a nice AC discount code (thanks to this forum) to purchase a flight in a refundable fare class. AC website says no fee for rebooking, just the difference, but how would this be calculated when the original fare was purchased at 30% discount? Would they keep the discount code and apply it to any change, or am I essentially losing the use of the discount on one leg.
I'm hoping to delay the return by one day.
Thanks
