Trying to get an answer if it possible to use an e certificate and skymiles in the same transaction.
I am trying to purchase 2 tickets for round trip flights RIC to DEN for myself and my wife. I have an e certificate that covers my fare and would like to use my skymiles to pay for her ticket, but can't seem to be able to do this combo on the Delta website.

Is anyone aware of a way to do this, by phone perhaps.

Appreciate the help!
