*SDC = Same-Day Confirmed--it allows you to switch to another flight on the same day, earlier or later than your original flight. The change can be made within 3 hours of when the first flight you want to take departs.
How could this be happening with SDC? Once you SDC then your are on your new flight and your old one is gone. You can't just miss your flight and then call 1/2 a day later to SDC. Anyway, I have seen them take 'no rides' out of the system pretty quickly and I would not even think about trying this. If you think you might miss your flight ... always call and get the segment taken out.
