I may even argue RDU in some extent. I was flying DFW-ATL-BOS, and the ATL-BOS cancelled. So the agent couldn't find anything via DTW/MSP/CVG/NYC, so he started getting creative and found seats with a routing of DFW-ATL-RDU-BOS. Didn't realize how big the operation was in RDU. Beautiful terminal as well.
