No VA, which on re checking did operate basically on time - 2015 departure ex Canberra (landed at 1930). About an hour after the QF flight scheduled departure time. On the surface it seems a bit odd as the fog seemed a lot worse around 2000 than at 1900, but as outlined upthread there are variables that may mean one aircraft can land while another can't.Ah. Into Canberra? Qantas did not offer any assistance to anyone.
