i booked a ticket on AC using a 20 off discount code they sent me. I went to cancel the ticket within 24 hours and rebook it, only to find out the discount coupon cannot be reused. I have been in the same situation with other NA airlines and this has never been an issue.

I have also seen that E75 meal voucher coupons have to be used during booking. You cannot stack coupons if you have a discount coupon AND a meal voucher coupon. In times like this, you would think the AC helpdesk would be able to override the system, but I've been told the system won't allow them to do it.

All of this looks to be related to a poorly coded system, which then become a 'Policy' and the customer gets the hit.

I've been a E50/ E75 for over 10 years continuously now and have decided to take my business elsewhere just for these reasons alone. I hope someone from AC is reading this!
