I don't see a thread on this subject just yet, for this new year. If there is one, please move this post.

My January 5 BKK-NRT SWU cleared one week before flying. My NRT-ORD segment cleared at booking.

All but one segment cleared at purchase for ORD-BKK-ORD in late April 2012. The segment that has not yet cleared is the return BKK-NRT. Hopefully it does clear before travel time.
