I, personally, like e-rewards. I get 500 to 1000 RR miles each month and they all apply to the companion pass. With two 50,000 welcome points and the e-rewards points one can get to a companion pass with minimal expense.
As I "work" on the internet slipping in the e-rewards surveys is easy to do. I wish there was a way for my wife to get e-rewards points. Does anyone know how to do that?
