I'm planning a day trip with the cheap JetBlue fares, and I want to rent a cheap car for the day. My father-in-law has 5 free days with Emerald Club, and he'll likely never use them on his own. Is it possible for him to reserve the car for me with this points, and I pick it up and rent it? I'm thinking a transfer of points would take too long, and I need the points in a little over a week. Ideas?
