Well, how about this one? If I fly CO in October, as a NW Silver, with few miles credited to my Onepass account, since I wanted to build my WP miles, should I take Onepass miles at double mileage or WP miles that earn me the usual extra 50% plus count towards gold (still a far distance away) and forego the double miles on CO? I hate losing miles.
