Make sure you keep a hard copy of your basis showing the "U" code. You receive this when they send you confirmation of your ticket being purchased. It probably doesn't matter with a U code, but it does if you have one of the 150% codes. If you get upgraded by EUA by CO, it will show as an R code which NW will only credit you 100% when CO reports to NW your mileage.
