Thanks all for the replies. Yes, I recently saw a post on one of the travel blogs about a United program where you donate miles to families to travel to see one another due to major illness or terminal diseases... which would have been NICE to know about before her death... but indeed maybe a worthy cause. That, or fly my dad somewhere who has been locked up taking care of her for so long. I do hope Delta does not have such a death database, they owe my Dad these miles at the absolute very least, he was such a saint, and Mom earned them. Out of any and all illegal things I'd ever do or consider doing, using Mom's miles for him after she died is EASILY the easiest and of which I'd feel absolutely guilt free. And yes, thankfully, we do have access to her accounts... her and my Dad were basically one and the same.
