My predictions are QF int will operate out of 5 airports only,
SYD / MEL / (insert asian airport here, most likely SIN) / LHR / LAX.
Everything else will be codeshared, sent to JQ or dropped completely.
They will speed up getting rid of the B747's
, they will move the A330's to JQ \ QF dom (prob replace the SYD-PER B744 with an A330 with skybed to compete with DJ on that route).
Everything int will be via an A380.
JQ will do feeder flights PER-SIN for connection onto a SIN - LHR.
I do see them retaining a couple of first class aircraft which will be used on certain flights at certain times, just so they can say they are still a "first class airline".
I don't know if Jetconnect will continue doing TT runs, or if Jetconnect will become part of JQ (neither would surprise me).
I really hope I'm wrong, but knowing Joyces actions until now...
