Most of my missing miles have now correctly posted. I did have one minor discrepancy for a flight that was missing the final PDX-SEA segment. I guess it's been a while since I submitted a missing AS flight, cause WOW is it nice now! I just popped in my confirmation code and flight date and it automatically recognized the missing segment and posted it immediately! Color me impressed.
Would advise everyone to check that ALL your segments have posted. That little 129-mile hop was worth 1000 miles to me.
