I've not flown ERJ-175 flights out of IAH. With an upcoming trip, I can fly various routings including one IAH mainline to ERJ-175 connection. Do the ERJ-175s fly exclusively from terminals C and E, or do they occasionally use terminal B? With a short connection, I prefer to avoid the Terminal Link as mechanical malfunction almost caused me to miss a recent connection. Thank you!

As an aside, IAH really needs an airside pedestrian connection between terminals B and C for when the Terminal Link malfunctions.
