I have qualified for the 3X promotion by flying 10,000 miles in January. I have an L/N "discount" flight coming up in March, so I wouldn't get any bonus. If I upgrade my seats using my electronic upgrade points ("stickers" for AA veterans), will this change my booking class so I actually receive triple miles despite paying the low-ball fare?</font>
Nope. Unless the agent makes a mistake when checking you in. You should be booked in R for the e-upgrade but the mileage code should reamin L or N -- your originally purchased fare.
