All 2400 Points Post
The retroactive registration worked for the 6 segment $19 RT between SAC and MTZ, as predicted by the_traveler.
Thus the 6 segments yielded 600 AGR points, plus the new 600 and 1200 points respectively from the 2 promotions, thus 2400 total plus the 40 from Mastercard and the AS miles mentioned earlier.
Thus, for $19, one gets enough points for a free RT (2000 points) from say SAC to LVS, which retails at over $100.
