I too am thinking of a trip where doing this would be perfect, but I cannot find a booking engine that allows me to. Hence my fond memories of the ITN.net. I am trying to book a trinagular trip routing AKL-MEL-SYD-AKL (or maybe CHC). I want to fly Emirates in F from AKL-MEL (to sample the A340-500), Qantas in coach MEL-SYD and Qantas in J to either AKL or CHC. I do not seem to be able to do this all on one booking.
