Bug when using trying to use Pay with Miles for someone else's ticket.

* have the amex reserve card
* also gold medallion
* browser - chrome or ie

I'm able to find the flight, get all the way to booking with, but when I try to purchase now, it says that delta can't verify my address. This happens whether I use the amex or another card to pay.

however, if I change the name of the passenger to my own name (and ff number) I am able to purchase.
