It actually will be pretty self explanatory.
Go to Membershiprewards.com
Then click "Use Points" and in that tab, "Airlines"
Click Delta, you will see a tab that says "Transfer Points" Click it, enter the amount, follow the steps and done.
Also, there is a 30% bonus going on now for transfers from Amex to DL, log in to your Delta account and check your eligible promotions, if it is listed, register for it before you initiate the transfer.
