Yep my mistake OP. Missed the part where you said you were already in IAH, my bad. Good luck with the SBY, hopefully if not they'll give you a hotel voucher and won't pull the weather card.

By the way experflyer is showing this for that flight, the UC agent should be able to force you onto the flight since you misconnected you shouldn't have to standby on this one, there is an open economy seat still showing.
