How can I keep the RR points for myself if I am the one paying for the seats? I notice they split between myself and the other passenger, but they are paid for on my SW card. Why should they get any points if I pay?
Thre's no way to do what you want. Points go to the ticket holder - regardless of who paid for the ticket. If you use a Chase RR CC, at least you'd get points for the ourchase.
