What this guy Gpohost posting right above this is proposing is not possible under Delta's points program so beware.
Delta's miles FAQ states:
Delta charges 1 cent per mile and a $30 transaction fee, plus tax, per transfer. ... You can transfer a maximum of 150,000 Delta miles from your account per year and a maximum of 30,000 miles per transaction
To transfer your 920,540 miles (even if you could do it, but you cannot) the fees would be $9235.00
You can buy tickets with your miles for someone else but only if they are flying with you.
