OK, i paid/flew B class on CO on 25NOV. Those miles posted by 30NOV. The return was paid B on CO on 29NOV. However, I stood by onto a NW flight that night. Those miles have not posted, although I have faxed a mileage request with boarding pass and receipt.

1. I assume I will get the NW miles instead of the CO miles, in other words, the flight I actually flew?

2. How long should I expect to wait for the return to post?

One complication is that the GA took my reissued NW ticket when I was upgraded at the gate. Being a newbie SE, I didn't know if that was standard or not... but now it means I have no ticket for the flight I actually flew (although of course I have the boarding pass and the original receipt for the CO return).
