Building itin SMF-IAD. Website only offered FC (P) outbound at $735 OneWay. Yet the seat map showed plenty E+. Re-booked going THRU IAD to alternate endpoints (chose GSO for the test), website offered E+ and the *RT* was under $700. Called, agent could only see the FC choice when the endpoint was set as IAD. Orbitz offered the same fare amount (>$700), but for an E+ seat. Crazy times.
