Sorry to ask so many questions....
I've found QF1 from Sydney - London which is just displayed as the Qantas metal A380 with one stop. Does this mean it will be the A380 all the way through? I know that one or two sectors displayed affects SC's, but does it affect points? My dad doesnt collect QFF points but he will family transfer to me so SC's don't really matter.
Yes it does effect points. Basically what happens is when you have the one flight number on a stopping service the points and status credits are calculated as if the stop didn't exist route rather than the actual route flown. So both status credits and 'miles' are slightly less booking say QF1 SYD-LHR via DXB rather than SYD-DXB and DXB-LHR as separate sectors.
