potentially booking SFO-IAH-CLT later this month. 45 minute connection in IAH. Today's version arrives at E5 and departs from B80 (I realize gates may not be the same in a few weeks, but E5-B80 looks like just about the worst case scenario).

Haven't flown through IAH much - is this doable without doing an OJ though the airport? (the running & jumping, not the stabbing).

Thanks.
