N621VA is re-entering service tomorrow (AS1960 SFO-SAN); I see no recent flights for this aircraft, and am unsure when it left GSO.
Meanwhile, N840VA appears to be scheduled to fly GSO-SFO today, and then re-enter service on Monday (AS1953 SAN-SFO? something appears to be missing from this schedule).
Could either of these be the first reconfigured A320s?
