The downside of Richmond is that you get to add an extra ~2 hours to most trips to the west coast. Either by the need to change planes in ATL/CLT/ORD/etc, or by having to drive to DCA/IAD to take a direct flight.
RIC is getting more direct flights as volume picks up. Breeze flies to SFO direct, but its not super regular and apparently they cancel them last minute (yikes!).
