Is -OAI painted in BA colours now and solely used by Comair?
Yes it is.
Will -OAH also go to Comair eventually, or still between the two, what configuration does it have at the moment, with business class seats in, same 116 seat capacity as the other -300s of Comair, or more for LCC operations?
At the moment OAH is used by Kulula (the only Kulula -300). Not 100% sure about config but would assume it is in the LCC config.
Is the Kulula -200 still flying, haven't seen it in GRJ for a long time?
Yes NNG still flying. Probably doesn't come to George because the pax loads are too good for a -200...
