It’s probably the 2nd bank out of IAH. Not quite as reliable as the first but should be ok. It’s so far off that I suspect there might be a schedule change that would give you a free rebooking. The fare I saw for a random day in Feb was crazy cheap. I would just grab it now. There is a later Cape Air. Should be able to rebook you to that flight however if you have several people in your party seats could be an issue.
