I'm less concerned about connecting on my outbounds to a RJ, for obvious reasons, but again, I've never connected through IAH, (only ended there), so I really appreciate everyone's input. Some of the connection times I have seen are 38 minutes, or 45 minutes. Sounds like I best err on the side of caution and take the 45 minutes.

Additional question - when flying in F, do you find that the FA will reserve overhead bin space for pax in F, or does Continental work it as a first come, first grab, kind of scene?
