Looks like DL increased the # of GCs per transaction to 5 now (5 + CC).
How many Delta Gift Cards can I redeem at one time?
Up to 5 Gift Cards can be redeemed per transaction on delta.com
However, I need to redeem more than 4. I know I can call, but I wonder if I cancel an itin booked with multiple GCs within 24hr, would it refund back to multiple GCs in original denomination OR one consolidated GC? If the latter, do that multiple times and voila. Any DPs on this?
