It's 5,600 miles for a $50 (digital) gift card. A $500 gift card is 55,600 miles. This is slightly less than the 1CPM return you get with Pay with Miles if you have a DL Amex card. Although considerably better than using miles for the physical goods in the Marketplace where return looks to be roughly an atrocious .25CPM.
