The IAH B gates are even more annoying than either the IAD or ORD commuter gates, as IAH places even more RJ flights out of them, and has the "Barn" as one gate, while the rest of the gates are normal gates with no seating for full flights. At least ORD and IAD don't have the barn, just some outside walking that is relatively short. Really, the barn is closer to DL's JFK or SLC commuter gates
